ABSTRACT:
A waveform digitizer includes a sampling bridge for producing a sequence of analog samples of an input waveform, the samples being calibrated by an amplifier having adjustable offset and gain and then converted to digital quantities for storage in an addressable memory. The digitizer also includes memory and time base control circuits permitting real and equivalent time sampling of repetitive waveforms and logic circuits providing hardware averaging of multiple data samples.
