In each embodiment of the present application, all channels of the radio frequency power amplifier of the electronic equipment in the related art adopt the parameters of the reference channel, and the adjacent channel leakage ratio of some channels does not meet the requirements, or the power supply voltage of the radio frequency power amplifier does not reach the minimum. , which leads to the problem of large energy consumption, and all electronic equipment of the same type adopt a set of working parameters of the prototype, and the ACLR of the channel of some electronic equipment does not meet the requirements or the power consumption is large, resulting in the electronic equipment of the same type To solve the problem of inconsistency in equipment performance, a calibration method for electronic equipment is proposed.

The method for calibrating electronic equipment proposed in the embodiment of the present application performs a calibration test on the reference channel according to the initial power supply voltage table of the reference channel corresponding to the electronic equipment to be calibrated, and performs a calibration test on each non- Reference channel for calibration testing. Therefore, according to the properties of the electronic device to be calibrated, all channels of each electronic device to be calibrated are calibrated to obtain the working parameters of each channel of the electronic device to be calibrated, thereby ensuring that when the electronic device works on any channel, the adjacent channel The leakage ratio can meet the requirements, and the power consumption of the radio frequency power amplifier is also better, and meanwhile, the consistency of the performance of the electronic equipment with the same property is improved.

FIG. 1 is a schematic flowchart of a method for calibrating an electronic device provided in an embodiment of the present application.

The electronic device calibration method provided in the embodiment of the present application can be executed by the electronic device calibration device provided in the present application. The above device is configured in the electronic device to calibrate the reference channel and non-reference channel of the electronic device to be calibrated.

Wherein, the electronic device in this embodiment may be any hardware device having a radio frequency power amplifier, such as a mobile phone, a palmtop computer, and the like.

As shown in Figure 1, the electronic equipment calibration method includes:

Step 101, according to the properties of the electronic device to be calibrated, obtain an initial supply voltage table of a reference channel corresponding to the electronic device to be calibrated, wherein the initial supply voltage table includes each initial supply voltage.

In actual use, wireless communication usually has multiple bandwidths, and each bandwidth has multiple channels. For example, mobile phones usually have multiple bandwidths such as 2G, 3G, and 4G, and each bandwidth has multiple channels such as high, medium, and low.

In this embodiment, multiple channels under the same bandwidth are taken as an example. For the same bandwidth, one channel can be selected from multiple channels as the reference channel of the electronic device, for example, a channel with a frequency in the middle is selected as the reference channel. The channel is called the non-reference channel.

In this embodiment, the attribute of the electronic device to be calibrated may be an electronic device model, a product serial number, or any other identifier that can uniquely identify the type or model of the electronic device to be calibrated. Also, the frequencies of the reference channels of the electronic devices of the same property are the same.

Since the radio frequency power amplifier can adjust the transmission power according to the communication environment, in order to save power consumption, the power supply voltage of the radio frequency power amplifier can be adjusted according to the transmission power to reduce power consumption. In this embodiment, the initial power supply voltage table includes each initial power supply voltage, that is, the initial power supply voltage table has multiple initial power supply voltages.

When obtaining the initial power supply voltage table of the reference channel corresponding to the electronic device to be calibrated, as a possible implementation, the power supply voltage table of the reference channel of the test prototype can be used as the initial power supply voltage table of the electronic device to be calibrated.

In actual use, in order to reduce the power consumption of the RF power amplifier, as another possible implementation, before obtaining the initial supply voltage table, voltage tracking calibration or Power tracking calibration to determine the initial supply voltage table. Specifically, when an electronic device with the same properties as the electronic device to be calibrated works under the reference channel, the power supply voltage and the radio frequency gain index are automatically adjusted according to the transmit power of the radio frequency power amplifier, so that the mapping relationship between the power supply voltage and the radio frequency gain index can be established, A power supply voltage table is obtained, and the power supply voltage table is used as an initial power supply voltage table of a reference channel corresponding to the electronic device to be calibrated.

Through the initial power supply voltmeter determined according to the voltage tracking calibration or power tracking calibration, when the electronic equipment works on the reference channel and transmits high power, it can use a large supply voltage for power supply; when transmitting low power, it can use a smaller supply voltage, RF power The supply voltage of the amplifier varies dynamically with the power output level. Compared with the fixed supply voltage method, the power consumption of the radio frequency power amplifier can be significantly reduced.

Step 102: Perform a calibration test on the reference channel of the electronic device according to the initial power supply voltage table, and determine a first power supply voltage table corresponding to the reference channel of the electronic device to be calibrated.

In practice, even electronic devices with the same attribute may have different performances of electronic components, so the same channel of different electronic devices with the same attribute adopts the same set of operating parameters, and some channels of electronic devices may not meet ACLR, or the power Can not achieve the best, resulting in inconsistent performance of electronic devices with the same properties.

In this embodiment, after the initial supply voltage table is obtained, a calibration test is performed on the channels of the electronic device to be calibrated to obtain a supply voltage table for each channel.

In this embodiment, a calibration test may be performed on the reference channel of the electronic device to be calibrated based on the initial power supply voltage table of the reference channel, to determine the first power supply voltage table corresponding to the reference channel of the electronic device to be calibrated. Wherein, the first supply voltage table includes each first supply voltage.

In practice, the first power supply voltage corresponding to the reference channel of the electronic device to be calibrated can be determined according to the ACLR or transmit power value obtained when the electronic device to be calibrated works under the reference channel with the working parameters in the initial supply voltage table, and then Get the first supply voltage table.

In this embodiment, by performing a calibration test on the reference channel of the electronic device to be calibrated according to the initial power supply voltage table, the first power supply voltage table of the reference channel is obtained, so that the reference channel of each electronic device to be calibrated with the same attribute can be obtained. Working parameters, so as to ensure the consistency of the performance of the electronic equipment to be calibrated with the same property working under the reference channel.

Step 103 , according to the first supply voltage table, perform calibration test on each non-reference channel of the electronic device to be calibrated respectively, and determine a second supply voltage table corresponding to each non-reference channel of the electronic device to be calibrated.

In practice, all channels of electronic equipment use the parameters of the reference channel, and the adjacent channel leakage ratio of some channels does not meet the requirements, or the power supply voltage of the RF power amplifier does not reach the minimum, resulting in large energy consumption.

In this embodiment, after the reference channel is calibrated, each non-reference channel may be calibrated respectively according to the first power supply voltage table of the reference channel to obtain the second power supply voltage table of each non-reference channel. Wherein, the second power supply voltage table includes each second power supply voltage.

When performing a calibration test on a non-reference channel, the electronic equipment to be calibrated can be controlled to work in a non-reference channel with the parameters in the first supply voltage table, so as to obtain the calibration electronic equipment to work in a non-reference channel with the parameters in the first supply voltage table ACLR or transmit power value when the channel is down, and determine the second power supply voltage of the non-reference channel according to the ACLR or transmit power value.

In this embodiment, each non-reference channel is calibrated according to the first power supply voltage table of the reference channel, and the second power supply voltage table of each non-reference channel is obtained, thereby ensuring that when the electronic device works on a non-reference channel, the ACLR satisfies Requirements, and make the RF power amplifier power consumption to achieve better.

It should be noted that, in the embodiment of the present application, the process of performing a calibration test on the electronic device to be calibrated can be implemented at any stage of the complete machine test of the electronic device, for example, during the complete machine calibration test, by using the calibration test provided by this application method, calibrate the working parameters corresponding to each channel of the electronic equipment, or use the calibration test method provided by this application to calibrate the working parameters corresponding to each channel of the electronic equipment in the non-signalling comprehensive test stage, etc., this implementation Examples are not limited to this.

In the electronic device calibration method of the embodiment of the present application, the reference channel is calibrated and tested according to the initial power supply voltage table of the reference channel corresponding to the electronic device to be calibrated, and each non-reference channel is calibrated according to the first power supply voltage table of the calibrated reference channel. channel for calibration testing. Therefore, according to the properties of the electronic device to be calibrated, all channels of each electronic device to be calibrated are calibrated to obtain the working parameters of each channel of the electronic device to be calibrated, thereby ensuring that when the electronic device works on any channel, the adjacent channel The leakage ratio can meet the requirements, and the power consumption of the radio frequency power amplifier is also better, and meanwhile, the consistency of the performance of the electronic equipment with the same property is improved.

On the basis of the foregoing embodiments, the initial power supply voltage table further includes an initial radio frequency gain index corresponding to the initial power supply voltage mapping. For the calibration test of the reference channel of the electronic device in step 102 above, as a possible implementation, it can be based on the electronic device to be calibrated when it works on the reference channel with the initial power supply voltage and the initial radio frequency gain index, and transmits the preset power. The adjacent channel leakage ratio determines the first supply voltage of the reference channel.

FIG. 2 is a schematic flowchart of a method for performing a calibration test on a reference channel of an electronic device provided in an embodiment of the present application.

As shown in Figure 2, the method for calibrating the reference channel of the electronic device includes:

Step 201, obtain the adjacent channel leakage ratio when the electronic device to be calibrated works on the reference channel with the initial power supply voltage and the initial radio frequency gain index, and transmits preset power.

ACLR is the ratio of the transmit power to the power falling on the adjacent channel, and it is an index used to measure the energy of the radio frequency power amplifier outside the specified channel. It can be understood that the larger the ACLR, the smaller the impact on adjacent channels.

In this embodiment, the ACLR when the calibration electronic device works on the reference channel with the initial power supply voltage and the initial radio frequency gain index and transmits preset power is acquired to perform power supply voltage compensation. Wherein, the preset power can be set as required.

Specifically, a set of mutually mapped initial power supply voltage and initial radio frequency gain index can be selected from the initial power supply voltage table, and the power supply voltage and radio frequency gain index of the electronic device to be calibrated can be adjusted to the initial power supply voltage and initial radio frequency gain index, And control the electronic equipment to be calibrated to work in the reference channel, and transmit the preset power, so as to obtain the ACLR when the electronic equipment to be calibrated works in the reference channel with the initial power supply voltage and the initial radio frequency gain index, and transmits the preset power.

For example, the selected initial power supply voltage and initial RF gain index mapped to each other are 2.3V and 52dB respectively, and the preset power is 20dBm, then the electronic equipment to be calibrated is obtained when it works in the reference channel at 2.3V and 52dB and transmits 20dBm power ACLR.

Step 202: Determine a first voltage compensation value corresponding to the reference channel according to the adjacent channel leakage ratio and the target adjacent channel leakage ratio.

In order to prevent the radio frequency power amplifier from working on the current channel, the adjacent channel will be greatly affected, and the target ACLR can be set.

After acquiring the ACLR when the electronic device to be calibrated works under the reference channel with the initial power supply voltage and the initial radio frequency gain index and transmits preset power, determine the first voltage compensation value corresponding to the reference channel according to the acquired ACLR and the target ACLR. Specifically, a difference may be made between the acquired ACLR and the target ACLR, and then the difference is multiplied by the first adjustment coefficient to obtain the first voltage compensation value of the reference channel. As shown in formulas (1) and (2).

ΔACLR=ACLR-ACLRtarget (1)

ΔVCC _A =x*ΔACLR (2)

Among them, ACLR is the ACLR when the electronic device to be calibrated is working under the reference channel with the initial power supply voltage and the initial RF gain index, and transmits the preset power; ACLRtarget is the target ACLR; x is the first adjustment coefficient; ΔVCC _A is the reference channel The corresponding first voltage compensation value.

It should be noted that the adjustment coefficients x corresponding to the reference channels of different electronic devices to be calibrated may be the same or different. This embodiment does not limit it.

In addition, since the ΔACLR calculated by the above formula (1) may be a positive number or a negative number, correspondingly, the first voltage compensation value calculated according to the above formula (2) may also be a positive number or a negative number.

In this embodiment, the first voltage compensation value of the reference channel is obtained according to the obtained ACLR and the target ACLR, which can ensure that the ACLR of the reference channel of the electronic device to be calibrated can meet the requirements.

Step 203: Determine the first power supply voltage of the reference channel of the electronic device to be calibrated according to the initial power supply voltage and the first voltage compensation value.

In this embodiment, after obtaining the first voltage compensation value corresponding to the reference channel, the initial power supply voltage and the first voltage compensation value may be added to obtain the first power supply voltage of the reference channel.

Assuming that the initial power supply voltage is VCC, and the first voltage compensation value corresponding to the reference channel is ΔVCC _A , then the power supply voltage VCC _A of the reference channel may be as shown in formula (3).

VCC _A ＝VCC+ΔVCC _A (3)

After the power supply voltage of the reference channel is obtained, the first power supply voltage table corresponding to the reference channel of the electronic device to be calibrated can be obtained according to the mutual mapping relationship between multiple sets of first power supply voltages of the reference channel and the initial radio frequency gain index.

In this embodiment, the first voltage compensation is determined according to the ACLR and the target ACLR when the electronic device to be calibrated is working on the reference channel with the initial power supply voltage and the initial radio frequency gain index and transmits the preset power, and according to the first voltage The compensation value compensates the initial power supply voltage, and the power supply voltage of the reference channel after compensation is compared with directly using the initial power supply voltage as the power supply voltage of the reference channel, which can not only ensure that the ACLR of the reference channel meets the requirements, but also ensure the operation of the RF power amplifier The power consumption is better when the reference channel is used.

In the foregoing embodiment, the initial supply voltage table may further include a reference power range corresponding to the initial supply voltage mapping. In practice, when obtaining the initial power supply voltage table, any electronic device with the same properties as the electronic device to be calibrated can be controlled to work in the reference channel, and when transmitting different power values, the corresponding power supply voltage and RF gain index can be obtained. A reference power range is formed according to the maximum transmit power value and the minimum transmit power value corresponding to the same power supply voltage and radio frequency gain index.

For example, when the transmit power is 20dBm, the corresponding power supply voltage is 2.3V and the RF gain index is 52dB; the transmit power is 21.8dBm, the corresponding power supply voltage is 2.3V and the RF gain index is 52dB, and the power supply voltage is 2.3V and the RF gain index is 52dB, the corresponding maximum transmit power is 21.8dBm, and the minimum value is 20dBm, then [20dBm, 21.8dBm] can be used as a reference power range corresponding to a power supply voltage of 2.3V and an RF gain index of 52dB.

Thus, the mapping relationship between the reference power range, the initial power supply voltage and the initial radio frequency gain index can be obtained. It can be understood that by adjusting the power of the radio frequency power amplifier, multiple sets of reference power ranges, initial power supply voltage and initial radio frequency gain index mapped to each other can be obtained, that is, an initial power supply voltage table can be obtained.

It can be understood that a set of initial power supply voltage and initial radio frequency gain index corresponds to a reference power range, which means that when the power value transmitted by the electronic device is within the reference power range, the initial power supply voltage corresponding to the reference power range can be used as the radio frequency power The amplifier is powered.

Before step 201, the preset power may be determined according to the reference power range. In specific implementation, a value can be arbitrarily selected from the reference power range as the preset power. For example, a power value close to the lower limit of the reference power range is selected as the preset power.

In practice, usually when the communication environment is poor or the electronic equipment is far away from the base station, the electronic equipment may need to transmit the maximum power within the reference power range to ensure the communication quality when the electronic equipment works under a certain power supply voltage and RF gain index.

In this embodiment, the maximum power within the reference power range can be used as the preset power to obtain the ACLR when the electronic device to be calibrated works under the reference channel with the initial power supply voltage and the initial RF gain index, so that according to the obtained ACLR and target ACLR, determining the first power supply voltage when the electronic equipment to be calibrated works under the reference channel with the initial power supply voltage and the initial radio frequency gain index, and transmits the maximum power. Furthermore, the first supply voltage table corresponding to the reference channel of the electronic device to be calibrated can be obtained according to multiple sets of initial supply voltages, initial radio frequency gain indices, and the mutual mapping relationship between the first supply voltages.

It can be understood that since the ACLR when the reference channel transmits the maximum power meets the requirements, when the corresponding reference channel transmits a signal with a power lower than the maximum power, the corresponding ACLR value also meets the requirements.

In the above embodiment, the initial supply voltage table includes the initial supply voltage, the initial radio frequency gain index and the reference power range mapped to each other. As another possible implementation, the initial power supply voltage table may include the initial radio frequency gain index and the initial power value corresponding to the initial power supply voltage mapping, that is, the initial power supply voltage table includes mutually mapped initial power supply voltage, initial RF gain exponent and initial power value.

When obtaining the initial power supply voltage table, any electronic device with the same properties as the electronic device to be calibrated can be controlled to work under the reference channel to obtain the corresponding power supply voltage and RF gain index, thereby obtaining the initial power supply voltage and initial RF gain Index, and the mapping relationship between the corresponding transmit power values.

For example, when the transmission power is 20.5dBm, the corresponding power supply voltage is 2.3V and the RF gain index is 52dB, then the RF gain index is 52dB, the power supply voltage is 2.3V and the transmitted power value is 20.5dBm.

It can be understood that by adjusting the power of the radio frequency power amplifier, multiple sets of initial power values, initial power supply voltage and initial radio frequency gain index mapped to each other can be obtained, that is, an initial power supply voltage table can be obtained.

Based on the above content, for the calibration test of the reference channel of the electronic device in the above step 102, as another possible implementation, the first power transmitted when the electronic device to be calibrated works on the reference channel with an initial radio frequency gain index can be value to determine the first supply voltage for the reference channel.

FIG. 3 is a schematic flowchart of another method for performing a calibration test on a reference channel of an electronic device provided in an embodiment of the present application.

As shown in Figure 3, the method for performing calibration test on the reference channel of the electronic equipment includes:

Step 301, acquire a first power value transmitted by the electronic device to be calibrated when it works on a reference channel with an initial radio frequency gain index.

Specifically, a set of mutually mapped initial radio frequency gain index, initial power supply voltage and initial power value can be selected from the initial power supply voltage table corresponding to the reference channel of the electronic device to be calibrated, and the radio frequency gain index of the electronic device to be calibrated can be adjusted to to obtain the initial radio frequency gain index, and control the electronic device to be calibrated to work on the reference channel, so as to obtain the first power value transmitted when the electronic device to be calibrated works on the reference channel with the initial radio frequency gain index.

For example, if the selected initial power supply voltage, initial RF gain index and initial power value mapped to each other are 2.3V, 52dB, and 20.5dBm respectively, then obtain the transmitted power value of the electronic device to be calibrated when it works on the reference channel with an initial RF gain index of 52dB .

Step 302: Determine a second voltage compensation value corresponding to the reference channel according to the first power value and the initial power value.

After obtaining the first power value transmitted when the electronic device to be calibrated works on the reference channel with the initial radio frequency gain index, determine the second voltage compensation value corresponding to the reference channel according to the obtained first power value and the initial power value. Specifically, a difference may be made between the acquired first power value and the initial power value, and then the difference is multiplied by a second adjustment coefficient to obtain the second voltage compensation value of the reference channel. As shown in formulas (4) and (5).

ΔP=PP _r (4)

ΔVCC _p =y*ΔP (5)

Among them, P is the first power value transmitted by the electronic device to be calibrated when it works on the reference channel with the initial RF gain index; P _r represents the initial power value; ΔP is the difference between the first power value and the initial power value; y is the second adjustment coefficient; ΔVCC _p represents the second voltage compensation value corresponding to the reference channel of the electronic device to be calibrated.

It should be noted that the adjustment coefficients y corresponding to the reference channels of different electronic devices to be calibrated may be the same or different. This embodiment does not limit it.

In addition, since the ΔP calculated by the above formula (4) may be a positive number or a negative number, correspondingly, the second voltage compensation value ΔVCC _p calculated according to the above formula (5) may also be a positive number or a negative number .

In this embodiment, according to the obtained first power value and initial power value, the second voltage compensation value of the reference channel of the electronic device to be calibrated is obtained, which can ensure that the ACLR of the reference channel can meet the requirements, and the power consumption of the radio frequency power amplifier can be achieve better.

Step 303: Determine the first supply voltage of the reference channel according to the initial supply voltage and the second voltage compensation value.

In this embodiment, after obtaining the second voltage compensation value corresponding to the reference channel of the electronic device to be calibrated, the second voltage compensation value can be compared with the initial power supply voltage corresponding to the initial radio frequency gain index used when obtaining the first power value. Add to get the first supply voltage of the reference channel. As shown in formula (6).

VCC _p ＝VCC+ΔVCC _p (6)

Wherein, VCC _p is the first power supply voltage of the reference channel of the electronic device to be calibrated, VCC is the initial power supply voltage, and ΔVCC _p is the second voltage compensation value corresponding to the reference channel of the electronic device to be calibrated.

After the first power supply voltage of the reference channel is obtained, the mutual mapping relationship between the first power value, the first power supply voltage of the reference channel and the initial radio frequency gain index can be obtained, according to multiple groups of mutually mapped first power values, reference channel The first supply voltage and the initial RF gain index are used to obtain the first supply voltage table.

In this embodiment, the second voltage compensation value is determined according to the first power value transmitted when the electronic device to be calibrated works on the reference channel with the initial radio frequency gain index, and the initial power supply voltage of the reference channel is determined according to the second voltage compensation value. Compensation, using the compensated initial power supply voltage as the first power supply voltage of the reference channel of the electronic device to be calibrated, compared with directly using the initial power supply voltage as the power supply voltage of the reference channel of the electronic device to be calibrated, can ensure that the ACLR of the reference channel satisfies Requirements, and can ensure that the power consumption of the RF power amplifier is optimal when it works on the reference channel.

On the basis of the foregoing embodiments, it is assumed that the electronic device to be calibrated includes N non-reference channels. After determining the first power supply voltage table corresponding to the reference channel of the electronic device to be calibrated, the calibration test can be carried out one by one for the N non-reference channels of the electronic device to be calibrated according to the first power supply voltage table, and the N non-reference channels corresponding to each Second supply voltmeter.

In order to improve the testing efficiency of the electronic device to be calibrated, as another possible implementation, M non-reference channels may be selected from N non-reference channels for calibration testing, where M is smaller than N. Then, according to the second supply voltage tables of the M non-reference channels, the second supply voltage tables of the remaining N-M non-reference channels are obtained.

FIG. 4 is a schematic flowchart of a method for performing calibration tests on non-reference channels of an electronic device to be calibrated according to an embodiment of the present application. As shown in Figure 4, the method for respectively performing calibration tests on each non-reference channel of the electronic device to be calibrated includes:

Step 401 , perform a calibration test on M non-reference channels of the electronic device to be calibrated, and determine second supply voltages respectively corresponding to the M non-reference channels of the electronic device to be calibrated.

In this embodiment, the electronic device to be calibrated includes N non-reference channels, and M non-reference channels are selected from the N non-reference channels. According to the first power supply voltage table, the M non-reference channels are tested, and the second power supply voltages respectively corresponding to the M non-reference channels of the electronic device to be calibrated are determined.

Calibration testing on a non-reference channel is similar to testing on a reference channel.

As a possible implementation manner, the first supply voltage table includes an initial radio frequency gain index and a reference power range corresponding to the first supply voltage mapping. Specifically, the ACLR when the electronic device to be calibrated is working on a non-reference channel with a first power supply voltage and an initial radio frequency gain index and transmits preset power is acquired. Wherein, the preset power may be determined according to the reference power range included in the first supply voltage table.

Afterwards, according to the acquired ACLR and target ACLR, determine a third voltage compensation value corresponding to the non-reference channel, and determine a second power supply voltage of the non-reference channel of the electronic device to be calibrated according to the first power supply voltage and the third voltage compensation value. Thus, the second power supply voltages respectively corresponding to the M non-reference channels can be acquired.

According to the above method, for each of the M non-reference channels, according to the multiple sets of mutually mapped first supply voltages and initial gain radio frequency indices in the first supply voltage table, multiple sets of mutually mapped second Supply voltage, initial gain RF index, reference power range. Thus, multiple groups of the second power supply voltage, the initial gain radio frequency index, and the reference power range mapped to each other form a second power supply voltage table corresponding to the non-reference channel.

It should be noted that the target ACLR of the non-reference channel may be the same as or different from the ACLR of the channel.

As another possible implementation manner, the first power supply voltage table includes an initial radio frequency gain index and a first power value corresponding to the first power supply voltage mapping. Specifically, the second power value transmitted by the electronic device to be calibrated when it works on a non-reference channel with the initial radio frequency gain index in the first power supply voltage table is obtained. A fourth voltage compensation value corresponding to the non-reference channel is determined according to the second power value and the first power value. Afterwards, according to the first power supply voltage and the fourth voltage compensation value, the second power supply voltage of the non-reference channel is determined.

According to the method above, for each of the M non-reference channels, multiple sets of first power supply voltages, initial gain radio frequency indices, and first power values that map to each other in the first supply voltage table can be used to obtain multiple sets of The second power supply voltage, the initial gain radio frequency index, and the second power value are mutually mapped. Thus, multiple groups of the second power supply voltage, the initial gain radio frequency index, and the second power value mapped to each other form a second power supply voltage table corresponding to the non-reference channel.

Step 402, according to the second power supply voltages respectively corresponding to the M non-reference channels, determine the second power supply voltages respectively corresponding to the N-M non-reference channels.

In this embodiment, the second power supply voltages respectively corresponding to the N-M non-reference channels may be determined according to frequency differences between adjacent non-reference channels.

Specifically, the frequency differences between the jth non-reference channel and the j-1th non-reference channel and the j+1th non-reference channel are calculated respectively. Wherein, the jth non-reference channel is a non-reference channel for which the second supply voltage needs to be determined. The j-1th non-reference channel and the j+1th non-reference channel are non-reference channels for which the second power supply voltage is known.

Then, according to the frequency difference, the second power supply voltage corresponding to the j-1th non-reference channel, and the second power supply voltage corresponding to the j+1th non-reference channel, determine the second power supply corresponding to the j-th non-reference channel Voltage.

Assume that the frequencies of the j-1th, jth and j+1th non-reference channels are f _j-1 , f _j and f _j+1 respectively, and the corresponding second supply voltages are V _j-1 , V _j and V _j+1 . According to formula (7), V _j can be obtained.

In this embodiment, according to the second power supply voltages corresponding to the M non-reference channels respectively, the linear difference is used to determine the second power supply voltages of the remaining N-M non-reference channels among the N non-reference channels, which can save the calibration time of electronic equipment . That is, when the non-reference channels of the electronic equipment to be calibrated are calibrated, the calibration test can be performed on some of the non-reference channels first, and the remaining non-reference channels are determined by the second power supply voltage corresponding to the calibrated non-reference channels, which can greatly save the cost of Calibration test time for non-reference channels, thereby saving calibration time for electronic equipment to be calibrated.
