1
The range of real-time rates, expressed in samples/second, at which a digitizer samples signals at its inputs and stores
the samples in memory to produce a record of time-sequential samples.
2
The range of waveform rates for interpolated (or equivalent-time on the TDS 700D) waveform records.
3
The Waveform Rate (WR) is the equivalent sample rate of a waveform record. For a waveform record acquired by
real-time sampling of a single acquisition, the waveform rate is the same as the real-time sample rate; for a waveform
created by interpolation of real-time samples from a single acquisition or, on applicable products, the equivalent-time
sampling of multiple acquisitions, the waveform rate created is faster than the real time sample rate. For all these cases,
the waveform rate is 1/(Waveform Interval) for the waveform record, where the waveform interval (WI) is the time between
the samples in the waveform record.
