6.10 HTRIGGER SCPI COMMAND SUBSYSTEM
This section applies only to units with the External User Interface
(Currently only available on Ethernet versions).
The HTRIGGER function allows the user to apply an External User
Interface input signal to initiate a sequence or a voltage or current ramp.
Once a hardware trigger is run, Arm goes to 0 (not armed); however, the
last loaded sequence remains in memory.

6.10.2 HTRIGGER SCPI Command Reference
Command Description SCPI
HTRIGger
Hardware trigger subsystem.
N
:ABORt
Stops the execution of a currently running hardware trigger
function. In addition:
For Ramp: Clears all settings of voltage and current.
For Sequence: Sets the Arm function to 0 (not armed).
N
:RAMP
Executes voltage or current ramping function previously
programmed by the SOURce command, i.e.,
SOURce:VOLTage:RAMP
SOURce:CURRent:RAMP
N
:SEQuence
<string> (SGI only)
Loads a Sequence to be initialized by the external Hardware
Trigger. This command must be followed by the HTRIG:ARM
command before the Hardware Trigger becomes operational.
N
:SEQuence? (SGI
only)
Returns the currently loaded sequence name
N
:ARM <boolean>
(SGI only)
Readies the last loaded sequence to run when the external
Hardware Trigger signal is issued.
1 = Ready to run sequence when Hardware trigger is engaged.
0 = Not Armed, Hardware trigger is ignored
NOTE: To arm a different sequence, issue the HTRIG:SEQ
command first.
N
:ARM? (SGI only) Returns the ready status of the last loaded sequence.
1 = Ready to run sequence when Hardware trigger is engaged.
0 = Not Armed, Hardware trigger is ignored
NOTE: To load a new sequence to be armed you must issue
the HTRIG:SEQ command first.
