Especially, the transmission power should meet the requirement of high precision (for example, the transmission power is controlled at 0.1dB precision), and since the transmission power parameter of the device itself is limited, the specified transmission power can only be approximately achieved, the generated error is relatively large, and the precision requirement cannot be ensured. Thus, accurate control of transmit power can be accomplished by adding a digital variable attenuator(s) to the transmit path of the device, in combination. The transmission power Pt and the attenuation value Pa of the digital variable attenuator are changed by adjusting the transmission power parameter and the gear of the digital variable attenuator, and the requirement of the final transmission power of high-precision control equipment is met.

Therefore, the parameters need to be matched in groups one by one at different frequency points, but when the transmission power parameters of the equipment are more and the gears of the digital variable attenuator are also more, the combinable data volume is very large, if more than two variable attenuators exist, the data volume generated by combination cannot be sequentially matched and searched for each group of parameters by adopting a conventional scheme.

In particular, the digital variable attenuator comprises a plurality of attenuation steps, each corresponding to a different attenuation value. The number of the digital variable attenuators is S, the attenuation values of all gears of each digital variable attenuator are obtained one by one at a specified frequency point F, the gear number of each digital variable attenuator is gs, and the gears of the digital variable attenuators can be the same or different.

For example, the system comprises 3 digital variable attenuators Pa1, Pa2, Pa3, the numbers of gears of which are 2, 4, and 4 respectively, and under the designated frequency point F, the attenuation data of each gear are measured as follows:
Pa1＝{0.1124,1.1323}
Pa2＝{0.1312,0.7169,1.4562,1.9115}

The transmit power parameter also typically includes a number of levels, each level corresponding to a particular transmit power. Acquiring the transmitting power of each level one by one under a specified frequency point F, wherein the level number of the transmitting power is M, and then the transmitting parameters are set Pt of all the transmitting powers under the specified frequency point F:

And respectively obtaining a transmitting power parameter set Pt corresponding to the transmitting power parameter at the appointed frequency point F and an attenuation value set Pas of the S attenuators. Assuming that the influence of the transmission parameter power and the digital attenuator on signals meets an additive principle, each element in a transmission power set Pt is selected one by one and added with each element in an attenuation value set Pas to obtain a plurality of theoretical transmission power values, and a set formed by all the theoretical transmission power values is a theoretical transmission power set. Therefore, an element Pt1 in Pt and an element in Pas of each attenuator are taken and added with Pt1+ Pa1-1+ + Pa2-1+ … + Pas-1 to obtain a theoretically calculated transmitting power Pt1+ Pa1-1+ + Pa2-1+ … + Pas-1, and a set Pc of all theoretical transmitting powers is calculated:
Pc＝{Pt1+Pa1-1++Pa2-1+…+Pas-1,
Pt1+Pa1-2++Pa2-1+…+Pas-1,
…
Ptm+Pa1-g1++Pa2-g2+…+Pas-gn}
it should be noted that each element in the transmission power set Pt is added to any one element in each of the S attenuation value sets Pa1 and Pa2 … Pas, respectively, and for example, Pt1+ Pa1-2+ + Pa2-1+ … + Pas-1 represents a theoretical transmission power obtained by adding the attenuation values of the attenuator No. 2 and No. 1 to the attenuation values of the attenuator No. 1 and No. 2, respectively, of the first-level transmission power parameter. Therefore, the number of elements included in the theoretical transmit power set Pc is: each element of M × (G1 × G2 × … × Gs), Pc corresponds to one transmission parameter Pt and the attenuation values Pa of the S attenuators.
For example, the transmission power adjustment parameters include 4 steps, including the 3 digital variable attenuators Pa1, Pa2, Pa3, and the corresponding theoretical transmission power set Pc is obtained through calculation.
The number of elements in Pc is: 4 × (2 × 4 × 4) ═ 128
The elements included in the Pc set are:
Pc1＝Pt1+Pa1-1+Pa2-1+Pa3-1＝1.1212+0.1124+0.1312+0.1211＝1.4859。

And (3) appointing the transmitting power Ps, and acquiring configuration parameters meeting the maximum transmitting power error Pe (for example, less than 0.1) by gradually iterating by adopting a negative feedback system of closed-loop control in order to search the transmitting power parameters corresponding to the appointed transmitting power Ps and the configuration of the attenuator gear.
Further, the searching for the configuration corresponding to the specified transmission power includes the following steps, as shown in fig. 2:
