Research and Implementation on Microwave Power Online Measurement and Compensation of Automatic Test System

摘要

Aiming at the problem of microwave cable power attenuation of automatic test system, this paper puts forward to a microwave power online measurement and compensation method and designs power measuring equipment. Before the test process, it is controlled by automatic test program, the measurement cable outputs signal power, returns the analog voltage, and then adjusts microwave signal source power, compensate the cable power attenuation. Finally, this method has been proved and implemented by combining the examples.
