3.14 TRIGGER SCPI COMMANDS
The SCPI commands associated with establishing external trigger signals are
listed in this section.

3.14.2 T RIGGER SCPI C OMMAND R EFERENCE
Command Description
TRIGger Trigger subsystem. = module number.
:DISPlay?
Displays the module’s usage of the GPIO Buss signals,
that are used in the currently loaded List. See LIST below.
: INP
Establish that on module n, trigger t is an input. t = a-d, fa
(front panel only, in the DC module). (Non-pass through
mode.)
: OUTP
Establish that on module n, trigger t is an output. t = a-d,
fa. (Non-pass through mode.)
: INP , OUTP
: OUTP , INP
The RFP’s GPIO Buss signals (t = a, b, c, or d) connected
to ‘fa’, the Modules Front Panel trigger, specifying
direction. The trigger signal is passed through the Module.
: INPut:SLOPe [POSitive |
NEGative | BOTH | NONE
1
]
Sets module n’s fa trigger input edge as positive, negative,
or both.
: OUTPut:SLOPe [POSitive |
NEGative | BOTH]
Sets module n’s fa trigger output edge as positive,
negative, or both.
: TRIG
2
Generate a trigger from module n, t = a-d, fa.
: WIDTh<+NRf>
n = Module number, sets Front Panel trigger output pulse
width in SLOPE POS / NEG mode. The WIDTh timing
range is 2.0e-6 to 2.097 seconds.
Note: At this time the ReFlex Power™ system only implements direct trigger mapping
‘a’ to ‘fa’, ‘b’ to ‘fb’, ‘c’ to ‘fc’ and ‘d’ to ‘fd.’
1 The TRIG:SLOPe NONE parameter disables the trigger and disconnects the ‘fx’ to ‘x’
connection.
2 The POSitive and NEGative trigger pulse’s on the Front Panel trigger output are not
retriggerable, if a trigger pulse is being produced, and another trigger out is
executed, it will be ignored, and no errors will be posted.
