2. Description of the Related Art In a mobile phone inspection system, a variety of measuring instruments (frequency counter, power meter, FFT, etc.) and a measuring instrument which also serves as a dedicated signal generator incorporating a signal generator are used. (Frequency range, sofarence level, etc.) and set the mobile phone for multiple measurement items (power level measurement, beat error rate measurement, time axis change power level measurement, phase / frequency measurement, etc.). measure.

[0003] The measurement of a portable telephone comprises the following operations.

[0004] A set value is given to a parameter corresponding to a measurement item.

[0005] Control the measuring instrument according to the set value.

[0006] Obtain measurement results.

[0007] In a conventional measuring instrument control apparatus, for example, as described in "Method of generalizing a control program in an automatic test system" described in Japanese Patent Application Laid-Open No. 04-119436, a control program is provided with a given parameter. The operation of controlling the measuring device based on the set value and obtaining the measurement result is sequentially and repeatedly executed. With reference to FIG. 6, an operation of a conventional measuring instrument control apparatus for sequentially executing measurement items in accordance with the number of input parameter setting values will be described. The operation of the conventional measuring instrument control device includes processes 200 to 203 shown in FIG.

Process 200: Parameter setting, that is, a set value of one type of parameter is set in the measuring device 5.

Process 201: Measurement device control, that is, the measurement device 5 is controlled to perform measurement.

Process 202: result input, ie, measuring device 5
Import measurement results from

Process 203: End of all measurement items, that is, end determination is performed. If the required number of parameter setting values has not been measured, "No" and the process 200 and the subsequent steps are repeated. If the required number has been measured, the operation ends with “Yes”.

In the result input of the process 202, even when a measuring instrument capable of simultaneously obtaining a plurality of measurement results is used, only the measurement result of the target measurement item is fetched into the internal variables of the program out of the fetched measurement results. Other measurement results have been discarded.

Therefore, even if the set values of the parameters are the same, when the measurement result of another measurement item is intended, the processes 200 to 201 are always executed repeatedly.

In the following description, it is assumed that a measuring instrument capable of simultaneously obtaining a plurality of measurement results by setting a set value of one type of parameter is used.

[0015]

In order to obtain measurement results of different measurement items even if the set values of the parameters are the same, the parameters are reset and the measurement results are taken in. And the measurement time of the measuring instrument becomes long.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a measuring instrument control apparatus according to an embodiment of the present invention. FIG. 2 is a diagram showing tables stored in the storage device in FIG. 1, and these tables show the relationship between parameters and measurement results. FIG. 3 is a flowchart showing the operation of the measuring instrument control device shown in FIG.

In FIG. 1, an input device 1 is used for inputting an instruction of a set parameter and a set value of the parameter itself. The display device 2 displays the set value of the designated parameter, and is used to input the set value of the parameter while checking the contents. When the measurement item is being executed, the set value of the parameter and the measurement result are displayed.
The storage device 3 stores the input set values of the parameters, and provides the set values of the parameters to the computer 4 when performing the measurement. The measurement result read from the measuring device 5 is also temporarily stored. The computer 4 reads out the input set values of the parameters from the storage device 3. Measuring instrument 5
In order to control
Give to. It instructs the measuring device 5 to start measurement and reads the measurement result.

Next, with reference to FIGS. 2 and 3, the association between the parameter set value and the measurement result and the processing procedure will be described.

In the inspection of the mobile phone, a combination of set values (including non-set values) given in advance for each parameter is provided. In the parameter table 10 of FIG. 2, a plurality of pairs of measurement numbers and data numbers are registered. The measurement number is a number for designating a measurement function composed of a combination of one or a plurality of measurement items of the measuring device 5 and set values of parameters. The computer 4 sends the measurement number to the measuring device 5
, The measuring instrument 5 executes the corresponding measuring function.
Usually, a plurality of measurement results are obtained by executing the measurement function.
The data number is a number for designating one required measurement result among the measurement results of a plurality of measurement items obtained by executing the measurement function by sending the measurement number to the measuring device 5.

In the table shown in FIG. 2, it is assumed that the measurement numbers take values from 1 to N and the data numbers take values from 1 to M. There is no inconvenience even if the measurement number and data number are entered in a character string that is easy for humans to understand,
In any case, since the processing is replaced with a numerical value inside the measuring instrument control apparatus, the numerical value is described here.

In a certain area of the storage device 3, addresses 1 to N are allocated to the flag table, and N + 1 to (M +
1) Address N is assigned to the measurement result table.
At address n (1 ≦ n ≦ N) of the flag table, a flag indicating execution or non-execution of the measurement function with the measurement number n is written. N + n, 2N + n,... M in the measurement result table 12
At the address N + n, the measurement result of each measurement item by executing the measurement function with the measurement number n is written in a predetermined order. Before performing the processing shown in FIG.
Enter the data number and measurement number in the field.

In FIG. 3, the process 100 writes a flag (0) in the flag table 11 at addresses 1 to N as initialization work.

In the process 101, a flag (1) is set at the address n (value of 1 to N) indicated by the measurement number sequentially read from the parameter table 10 in the flag table 11.

When this process is performed on the L measurement numbers, the flag (1) or the flag (0) is written in addresses 1 to N of the flag table 11.

Here, a description will be given using an example shown in FIG.
In the process 101, since the measurement numbers in the parameter table 10 of FIG. 4 are 1, 2, 4, 4, and 2, the flag (1) is written into the addresses 1, 2, and 4 of the flag table 11. .

In the process 102, the flag, 1 of the table 11,
The contents are read out sequentially from the address. In the example of FIG. 5, (1)
The flags are read in the order of (1), (0), and (1).

The process 103 determines the flag read in the process. If the flag is (0), control is transferred to step 104, and if the flag is (1), control is transferred to step 200.

The process 104 determines whether all the contents of the flag table 11 have been read. If it has not been read, control is transferred to step 102, and if it has been read, control is transferred to step 110.

The processing 200 is performed so that the measuring function is executed by the measuring device 5 with the measurement number whose flag is (1).
Set the value of the parameter of.

The process 201 controls the measuring device 5 to perform measurement.

The processing 202 is executed by m (1 ≦ m)
≤ M), and the control is transferred to the process 105.

In a process 105, the measurement results of the obtained m measurement items are stored in N + n, 2N +
n,... MN + n is written to an address predetermined by the measurement item (the result is the result of executing the measurement function with the measurement number n).

Here, a description will be given using an example shown in FIG.
Since the process 105 is always executed when the flag is (1), three processes are performed in the case of FIG. In the first process 105, the measurement result is input to the row at address 1, that is, addresses 5, 9, 13, 17, and 21. 2
In the second process 105, the row of address 2, that is, addresses 6-1
Measurement results are input to 0, 14, 18, and 22. In the last process 105, the row of address 4, that is, addresses 8, 12, 1
The measurement results are input to 6, 20, and 24.

The processing 110 is performed in the parameter table 10
Are sequentially read, and a measurement result corresponding to the measurement number n and the data number m is read from the address m × N + n of the measurement result table 12 and stored as a result of the measurement item.

This will be described with reference to the example shown in FIG. Process 110
Is the result of address 9 in the first result, the result of address 6 in the second result, and 3 based on the parameter table 10.
The result of address 12 is the fourth result, and the result of address 1 is the fourth result.
The result of No. 6 is read out as the measurement result, and the result of the address 14 is read out as the fifth result, and is stored as the result of each measurement item.

Assuming that the number of measurement numbers input to the parameter table 10 is L, it is necessary to set the parameter L times in order to perform the same measurement with the conventional measuring instrument control device.

In the measuring instrument control device of the present embodiment, when the maximum value N of the measurement number is L or less, the parameter setting needs to be performed at most N times, and (L−N) times compared with the conventional measuring instrument control device. The time for parameter setting, measurement, and measurement result input is reduced.

When the maximum value N of the measurement number is L or more,
Parameter setting up to L times is completed. The number of times of parameter setting, measurement, and measurement result input is reduced by the duplication of the measurement numbers input to the parameter table.

Generally, the control time of the measuring instrument, for example, the parameter setting time, the measuring time, and the acquisition of the measurement result are much longer than the execution time of the program.

Accordingly, although the overall processing speed is higher than that of the conventional measuring instrument control device, the measuring instrument control device of the present invention performs a plurality of program processes.
I understand that it is early.

Although the processing contents of the program are relatively complicated, the processing itself can be realized by simple address calculation, so that the program execution time hardly changes.

[0045]

The measuring instrument control apparatus and method according to the present invention include:
Of the measurement results measured by giving a set value of a certain parameter, the measurement results of all the obtained measurement items are stored in a storage device as well as the measurement result of the obtained measurement item, and the set values of the parameters are the same. On the other hand, when the measurement result of another measurement item is required, the necessary measurement result is read directly from the corresponding storage device without performing data operations such as searching and sorting.

Therefore, when a parameter set value is given to obtain a measurement result of a certain measurement item and measurement is performed, when a measurement result of another measurement item becomes necessary even if the parameter setting value is the same, the parameter is again set. It is not necessary to take the measurement result by giving the set value of, and save the time for parameter setting and the measurement time of the measuring instrument, shorten the execution time of the measurement item, and improve the production throughput.
