APPLICATION NOTE 3190
Coherent Sampling Calculator (CSC)

Abstract: This calculator provides a quick and easy way to select sinusoidal input test tones for the test of
analog-to-digital (ADC) converters. Based on the theory of coherent sampling, the calculator allows a user to
chose input and sampling frequencies as well as number of integer cycles within the sampling window and the
resolution (number of data point) of the FFT.
