6 List Sequence Measurements
Source
Sequencer
Allows you to set the state of the list sequencer. When the list sequencer is on, the source is outputting the
sequence defined by the sequencer. When the list sequencer is off, the source outputs a single waveform
segment or sequence (independent mode) at a single frequency and amplitude.
Key Path
Source, List Sequencer
Remote Command
:SOURce:LIST[:STATe] ON|OFF|1|0
:SOURce:LIST[:STATe]?
Example
:SOUR:LIST OFF
Notes
When the sequencer is set to ON, the list sequencer controls the output of the source.
Couplings
When in Sequence Analyzer mode and the list sequencer state is Off, Include Source is forced to No,
and the Include Source key is grayed out.
When in Sequence Analyzer mode and the list sequencer state is On, Include Source is available to
set. And, an ARB memory related operation, like load or delete will be rejected.

Initiate Sequence
Pressing this key arms the sequence for single execution. Once the sequence is armed the source begins
the sequence as soon as the trigger is received. If the trigger is set to Free Run, the sequence starts
immediately.
Key Path
Source, List Sequencer
Remote Command
:SOURce:LIST:TRIGger[:IMMediate]
Example
:SOUR:LIST:TRIG
Notes
When in Sequence Analyzer mode and Include Source is Yes, the Initiate list sequencer operation is
rejected, and the key is grayed out, since source list sequence request is sent to physics via Parallel
batch by sequence analyzer.
If the file needed by the sequencer is not already in ARB memory, the sequence cannot be initiated
and an error will be generated.
There is a blocking SCPI query which can be used to query if source list sequence being initiated
successfully or not. (see
"Query List Sequence Initiation Armed Status (Remote Command Only)" on
Query Source List Sequence Armed Status)
Dependencies
Under the Sequence Analyzer Mode, if Meas Setup->Include Source is set to YES, Source->List
Sequencer->Initiate Sequence is disabled.
