ABSTRACT:
A method and apparatus for digitally sampling electrical waveforms. A sampling circuit for sampling an electrical signal, a digitizing circuit for digitizing the samples produced by the sampling circuit and an acquisition memory for storing the samples are employed, the acquisition memory being partitioned into a plurality of frames. Each frame is triggered to store samples associated with a respective triggering event. After substantially all of the frames have been triggered, the contents of the acquisition memory are retrieved from the acquisition memory, filtered in an equalization filter and stored in a waveform memory for ultimate display as an ET record under software control. A plurality of digitizing circuits associated with respective inputs of a multi-channel digital sampling oscilloscope are interleaved to increase the sampling rate.
