Keysight M8195A Revision 2 – Arbitrary Waveform Generator User's Guide
The following controls are available:

Pre-cursor Taps #-1/#-5: Pre-cursor taps can be edited from tap #-1 (the
closest to the transition) up to tap #-5.
 Post-cursor Taps #1/#5: Post-cursor taps can be edited from tap #1 (the
closest to the transition) up to tap #5.
Additional Waveform Parameters Section

Waveform Length
It is an indicator only. The length is in samples of the resulting segment.
 Max. Length
Maximum waveform length must be used to force the resulting waveform to
be shorter or equal to a limit set by the user.
 Keep Sample Rate
This check box preserves the sampling rate to a user-defined value
irrespective of any other defined signal parameter. Keeping the sampling rate
to a fixed value may be necessary when multiple waveforms are created for
usage in a sequence or scenario. The "Set WL to Max" check box gets
activated when this check box is checked
 Set WL to Max
This checkbox is only available when "Keep Sample Rate" is selected. When
this option is selected, the waveform calculation algorithm always takes the
maximum waveform length as defined in the "Max. Wfm. Length" field. As the
waveform length must always be identical for all four channels, it is
recommended to check the "Set WL to Max" box in case different waveforms
from different SGFP tabs shall be downloaded to different channels. Record
length are calculated to contain an integer number of complete PRBS
sequences except when the "Set WL to Max" is checked. In this case the
number of symbols in the resulting waveform will be the closest integer for the
