| In military fields and so on astronautics observation, radar, electronic countermeasure, as well as each civil communication domain, to the launch day the line transportation signal's power amplifier is the influence entire launching system performance key equipment frequently. Therefore, the research power amplifier equipment's test method and the establishment corresponding power amplifier automated test system is not only the development daily surveying work need, is also the model project power amplifier equipment development production and the application important safeguard.This article introduced has selected the method which the high efficiency directional coupler and the measuring instrument combine, realizes carries on the completely automatic test to the power amplifier performance index the function. Has analyzed various plans measuring condition, according to work actual and my unit existing hardware condition designation concrete test method, has set up the hardware platform, has realized the software design and the automatic control with the VB software. Finally has also analyzed this system's survey uncertainty, and had designated has been carried on the experimental verification by the measurement of power rate amplifier. |
