:DATA? Query the points in the arbitrary waveform.
:APP <NRf>
[,<NRf>, ...<NRf>]
Append arbitrary data points: -1 to +1 (100 points max. per
instance of command).
:POIN? Query number of points in the waveform.
:COPY <NRf> Copy arbitrary points to NVRAM: 1 to 4

:EXTR Waveform external trigger commands: *
[:ENAB] <b> Enables/disables mode to externally trigger the
waveform generator: <b> = ON or OFF.
OFF
:ILIN <NRf> Specify trigger link input trigger line:
<NRf> = 0 (none) or 1 to 6.
0
:IGN <b> Sets whether or not to restart waveform upon
retriggering: <b> = ON or OFF.
OFF
:IVAL <NRf> Sets inactive value to output before/after
waveform: <NRf> = -1 to +1.
