7 Summary

This article has dispelled the confusion on coherent sampling versus noncoherent sampling test methods and proper FFT data capture for various high-speed/RF ADCs. The next time you are in the lab collecting data on your signal-chain ADC design, you need to have confidence in presenting accurate FFT data collection measurements and rectify any FFT burping, picket fence and binning follies.
