SSPARM?
Sub-Sampling Parameters Query. Returns the parameters necessary to
reconstruct a sub-sampled waveform (SSAC or SSDC command) when the
samples are sent directly to the GPIB output buffer. (Reconstruction is automatic
when the samples are sent directly to reading memory.)
The first parameter returned by SSPARM? is the number of bursts that contained
N samples. The second parameter is the number of bursts that contained N-1
samples. The third parameter returned is the value of N. For example, assume you
are sub-sampling a 10kHz signal and specify 22 samples with an effective_interval
of 5µs. In this example, the multimeter must use a total of 4 bursts: 2 bursts contain
6 samples each and 2 bursts contain 5 samples each. The values returned by
SSPARM? are then 2, 2, and 6.
