The power of short-wave transmitter has the problem of control precision, and the attenuation value table generated by calibration is the key. Aiming at this problem, a high-precision short-wave transmitter power calibration system is designed. Firstly, the composition of the transmitter system is introduced, and the non-linear relation between the accuracy of attenuation value table and AD value table generated by power calibration is analyzed. Secondly, the attenuation value adjustment algorithm is designed and tested and applied in practical engineering. Experimental results show that the accuracy of power control and performance of transmitter can be improved.
