Keysight M8195A Revision 2 – Arbitrary Waveform Generator User's Guide
Use the :TRACe subsystem to control the arbitrary waveforms and their respective
parameters:

Create waveform segments of arbitrary size with optional initialization.

Download waveform data with or without marker data into the segments.
 Delete one or all waveform segments from the waveform memory.
In the data formats shown below the fields have the following meanings:
DB7...DB0 - Sample as signed 8-bit value, valid range is -128 to +127.
M1, M2 – Marker bits for Marker 1 and 2 to be output on channel 3 and 4,
respectively.
