TRIGger[:SEQuence]:TYPE NORMal | GATE | POINT
TRIGger[:SEQuence]:TYPE?
This command sets the trigger type that controls the waveform’s playback.
The following list describes the trigger type command choices:
NORMal
Upon triggering, the waveform sequence plays according to settlings defined
by :INITiate:CONTinuous (only once or repeatedly)
GATE
An external trigger signal repeatedly starts and stops the waveform’s
playback. The time duration for playback depends on the duty period of the
trigger signal and the gate polarity selection. The waveform plays during the
inactive state and stops during the active polarity selection state. The active
state can be set high or low. The gate mode works only with an external
trigger source.
POINt
Upon triggering, only a single point of the sweep (list) is played.
*RST NORM
:TRIGger[:SEQuence]:SOURce
TRIGger[:SEQuence]:SOURce IMMediate|KEY|EXTernal|BUS
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
TRIGger[:SEQuence]:DELay
TRIGger[:SEQuence]:DELay?
This command sets the amount of time to delay the BENCHTOP MICROWAVE SOURCE response to
an external trigger.
The delay is a path (time) delay between when the BENCHTOP MICROWAVE SOURCE 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
TRIGger[:SEQuence]:SLOPe POSitive|NEGative|NP|PN
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
