:TRIGger[:SEQuence]:SOURce?
Description
Sets the source of sweep/measurement triggering where the following options are available:
• AUTO = The triggering source is automatic.

• EXTernal = The triggering source is from the rear panel external trigger port.
• REMote = The triggering source is provided remotely.
Returns the source of the sweep/measurement triggering.

:TRIGger[:SEQuence][:IMMediate][:REMote]
Description
Triggers a continuous sweep from the remote interface.
During the sweep, command execution continues and does not pause. The operation of this command is modified by the instrument state set by the :SENse:HOLD:FUNCtion and/or the :SENSE{1-16}:HOLD:FUNCtion commands. See the following subsystems for additional information:
• :SENSe:HOLD Subsystem
• :SENSe{1-16}:HOLD Subsystem
No query.
:TRIG and :TRIG:SING have different dynamic effects on the system, depending on the measurement mode. When in continuous standard mode the measurement process will continue, so there may be some ambiguity when data is transferred (was it from one sweep, partially two different sweeps, etc.). A single-sweep and hold or :TRIG:SING can avoid that ambiguity. Also certain measurements (such as TMS-True Mode Stimulus and IMS) require multiple sweeps behind the scenes and :TRIG will not access these extra sweeps, but :TRIG:SING will.
The operation of this command depends on the settings of the :SENSe:HOLD:FUNCtion, :TRIGger[:SEQuence][:REMote]:SINGle, and :TRIGger[:SEQuence][:IMMediate][:REMote] commands. Each setting combination is described in the sections below.

// Sweep State = The sweep is sweeping continuously
// Command Execution = The parser is ready for a command right away.

:SENSe:HOLD:FUNC SING and :TRIG
:SENSe:HOLD:FUNCtion SINGle
// Sweep State = The sweep does one complete sweep, goes into hold and stops.
// Command Execution = The parser is ready for a command.

:TRIG
:TRIGger[:SEQuence][:REMote]:SINGle
Description
Triggers a single sweep with synchronization from the remote interface.
No query.
During the sweep, command execution pauses until the sweep is complete. The operation of this command is modified by the instrument state set by the :SENse:HOLD:FUNCtion and/or the :SENSE{1-16}:HOLD:FUNCtion commands. See the following subsystems for additional information:
• :SENSe:HOLD Subsystem
• :SENSe{1-16}:HOLD Subsystem
