A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Aimed at test and other laboratory applications where instantaneous bandwidth, high gain, and moderate power output are required, the 350AH1 solid-state amplifier from AR RF/Microwave Instrumentation ...

Because test setups often are experimental in nature, the amplifier providing the test signal may accidentally drive into an open or short. Of course, if the DUT does not present a good 50-? load, the ...

Traditional analog test techniques and specifications, which are based on sine-wave testing, don't reflect the true performance of devices that process the discrete-multitone waveform. A unique ...

As many of you are aware, I am not champion of the classic 1kHz instantaneous distortion vs power all channels driven test popularized by most of the major audio magazines as an accurate way of ...
