TRIGger:CONTinuous <Trigger Continuous trigger initiation State>
Selects whether the R&S LCX starts and continues a measurement, or starts on initi-
ated trigger events.
To delay the measurement start to a certain extent, use command TRIGger:DELay.
Parameters:
<Trigger Continuous
trigger initiation
State>
ON
Restarts the measurement automatically after a measurement
cycle has been completed.
OFF
Starts a measurement cycle initiated by a trigger signal.
*RST: ON
Example: See Example "Triggering measurements" on page 242.
Manual operation: See "Measurement Mode" on page 81
TRIGger:DELay <Trigger Delay Time>
Sets a delay time that elapses after a trigger event before the measurement starts.
Parameters:
<Trigger Delay Time> Range: 0 s to 60 s
Increment: 0.001 s
*RST: 0 s
Default unit: s
Example: See Example "Triggering measurements" on page 242.

TRIGger[:IMMediate]
Starts a new measurement.
In manual trigger mode, the command triggers a single measurement cycle. When
completed, the R&S LCX waits for the next trigger event.
Example: See Example "Triggering measurements" on page 242.
Usage: Event
Manual operation: See "[Trig.]" on page 76
See "Measurement Mode" on page 81
