ABSTRACT:
A digitizer circuit for converting analog waveforms displayed upon a CRT screen into digital signals suitable for storage in memory employs a microprocessor to determine, from user-specified parameters, the times at which the output of the CRT vertical amplifier is to be sampled. The user has great flexibility in defining sample resolution and the location of the sample window on the displayed waveform in which the samples are to be taken and is permitted to intensify the sample window on the CRT display before any samples are taken in order to view the sample window in relation to the remainder of a displayed waveform.
