ABSTRACT:
An equivalent time sampler uses an oscillator for sampling an input waveform having a repetitive component. A periodic signal is derived from the input waveform, and an offset frequency is derived from the periodic signal. The periodic signal and offset frequency are input to an offset locked oscillator to generate a sampling frequency that is the combination of the periodic signal and the offset frequency. The sampling frequency is used to obtain a sample of the input waveform for each acquisition cycle of the waveform.
