Abstract：Aiming at the industrial problem that the power level of wideband radio communication tester is out of tolerance and time-consuming for calibration, this paper studies the test technology of output power and level measurement of wideband radio communication tester and the calibration method of the instrument parameters, on this basis, develops Automatic test and calibration system of the power level of the tester based on C# programming language. The experimental results show that this method can effectively correct and improve the power level quality of the tester, and shorten the correction time from 30 minutes to 5 minutes through the automation system, which provides a fast and low-cost power correction solution for the enterprise, and has good industrial application value.
