ABSTRACT:
A waveform acquisition apparatus and method permits a plurality of samples of an input signal to be taken for each trigger recognition event, and stored at predetermined memory addresses to provide a complete equivalent-time waveform in which all accumulated samples are in correct time relation to each other. The mathematical determination of each address is obtained by measuring the time difference between a trigger recognition event on each cycle of a repetitive signal and a next occurring sample clock following each trigger recognition event, and then using a microprocessor to compute the relative addresses.
