ABSTRACT:
A predictive time base control circuit for a waveform sampling system of the type which converts a sequence of analog waveform samples into a sequence of digital quantities for storage in an addressable acquisition memory. The time base circuit generates a sampling control signal which initiates sampling at the end of a time interval of programmable duration following detection of a triggering event in the waveform, and which maintains sampling thereafter at regular intervals. The time base circuit permits the sampling system to operate in an equivalent time mode in which repetitive waveform sections are sampled at progressively skewed sampling intervals with respect to a repetitive triggering event. The sampling control signal is also frequency divided, delayed, and then applied as a write control signal to the sampling system acquisition memory. The time base control circuit includes a memory addressing circuit responsive to the write control signal for incrementing the address of the acquisition memory by an adjustable step size each time data is stored in the memory, thereby facilitating proper ordering of sample data in the memory.
