Selecting the Optimum Test Tones and Test Equipment for Successful High-Speed ADC Sinewave Testing

Abstract: An earlier application note, \"Coherent Sampling vs. Window Sampling,\" covered the basics of coherent sampling. It showed differences between tests performed with coherent sampling and windowed sampling conditions. The following technical discussion is a follow-up note, which deals with the proper selection of test tones and instruments to successfully test and evaluate a high-speed ADC's AC performance.
