HIGH The waveform playback starts when the trigger signal goes high (active
state) and stops when the trigger signal goes low (inactive state).

:TRIGger[SEQuence]SOURce
[SOURce]:TRIGger[SEQuence]:SOURce IMMediate|KEY|EXTernal|BUS
[SOURce]:TRIGger[SEQuence]:SOURce?
This command sets the trigger source.
IMMediate
No waiting for a trigger event occurrs
KEY This choice enables manual triggering by pressing the front-panel
RFon/off.
EXTernal This choice enables the triggering of a sweep event by an externally
applied signal at the MOD IN connector.
BUS This choice enables triggering over the LAN using the *TRG or GET
commands.
*RST IMM
:TRIGger[SEQuence]:DELay
[SOURce]:TRIGger[SEQuence]:DELay
[SOURce]:TRIGger[SEQuence]:DELay?
This command sets the amount of time to delay the BNC MODEL 835-3 response to an
external trigger.
The delay is a path (time) delay between when the 835-3 receives the trigger and when
it responds to the trigger. The delay does not occur until you turn it on. You can set the
delay value either before or after turning it on.
:TRIGger[SEQuence]:SLOPe
[SOURce]:TRIGger[SEQuence]:SLOPe POSitive|NEGative
[SOURce]:TRIGger[SEQuence]:EXTernal:SLOPe?
This command sets the polarity for an external trigger signal while using the continuous,
single triggering mode. The POSitive and NEGative selections correspond to the high
(positive) and low (negative) states of the external trigger signal. For example, when you
select POSitive, the waveform responds (plays) during the high state of the trigger
signal. When the BNC MODEL 835-3 receives multiple trigger occurrences when only one
is required, the signal generator uses the first trigger and ignores the rest.
*RST POS
:TRIGGer:RETRigger
[SOURce]:RETRigger ON|OFF|IMMediate
[SOURce]:RETRigger?
This command enables or disables the ARB retriggering mode; the retrigger mode
controls how the retriggering function performs while a waveform is playing.
ON (1)
This choice specifies that if a trigger occurs while a waveform is playing,
the waveform will retrigger at the end of the current waveform sequence
and play once more.
OFF (0) This choice specifies that if a trigger occurs while a waveform is playing,
the trigger will be ignored.
IMMediate This choice specifies that if a trigger occurs while a waveform is playing,
the waveform will reset and replay from the start immediately upon
receiving a trigger.
*RST ON
