Generally, the exact computation of the output record length leads to values, that
don’t fulfill the granularity requirements of the M8195A waveform memory. Different
resampling modes, which slightly modify the resampling algorithm, are offered to
address this problem. The first term in brackets after the resampling mode is the
enumerator to be used in the corresponding SCPI command. The second one is the
name used in the Import Waveform Panel of the SFP.
Timing (TIMing, Timing)
Calculate the resampling factor from the input and output sample rates.
(1)
Calculate the output record length from the input record length and the resampling
factor. Round it to an integer value.
(2)
Adjust the output record length to the nearest integer fulfilling the granularity.
(3)
Adjust the resampling factor.
(4)
Adjust the output sample rate.
(5)
Keep-Sample-Rate (KSRate, Output_SR)
The first four steps are identical to the “Timing” mode. In the last step the input
sample rate is adjusted.
Keep-Waveform-Length (KWLength, Output_RL)
Adjust the output record length to the nearest integer fulfilling the granularity.
Adjust the resampling factor.
Adjust the output sample rate.
