I am a car antenna manufacturer, and the antennas we produce are equipped with FM and AM active band amplifiers and GPS amplifiers, and after production, we test the antennas with the signal generator device and spectrum analyzer. Now I want to make a simple tester for each of the amplifiers so that they can be tested before assembly and we don't have to test them in the last step and don't need the generator signal and the analyzer spectrum. Please show me how to make a simple tester.

 

Please show all your threshold specs and interface
