6. Set the Marker Output Source
[SOURce:]MARKer:FEED “[SOURce:]LIST[1]”
This command selects the
LIST[1] source as the source that outputs a
marker pulse at the “Marker Out” front panel terminals (see Chapter 6
for information on other sources).
7. Setup the Waveform Segment
[SOURce:]LIST[1][:SEGMent]:SELect <name>
[SOURce:]LIST[1][:SEGMent]:DEFine <
length>
8. Store the Waveform Segment as Combined Signed DAC Data
[SOURce:]LIST[1][:SEGMent]:COMBined <combined_list>
This command stores the waveform segment into segment memory in
the Signed format set by the
[SOURce:]ARBitrary:DAC:FORMat
SIGNed
command. The data is sent as a combined list with the
marker bit selected.
9. Setup the Sequence and Generate Output
[SOURce:]LIST[1]:SSEQuence:SELect <name>
[SOURce:]LIST[1]:SSEQuence:DEFine <
length>
[SOURce:]LIST[1]:SSEQuence:SEQuence <
segment_list>
[SOURce:]FUNCtion:USER <
name>

BASIC Program Example (COMBSIGN)
1 !RE-STORE"COMBSIGN"
2 !This program downloads an arbitrary waveform as a combined
3 !(voltage and marker) list of signed (2’s complement) DAC codes.
4 !The data is sent in an IEEE-488.2 definite length block in 16-bit
5 !integer format. The waveform is a 200 point, -5V to +5V ramp wave.
