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 equivalent time or interpolated 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 by equivalent-time sampling of multiple acquisitions, the waveform rate is faster than the
real time sample rate. For all three 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.
4 The maximum record length of 15,000 samples (50,000 samples with Option 1M) is selectable with all acquisition modes except
Hi Res. In Hi Res, the maximum record length is 5,000 samples (15,000 samples with Option 1M).
