The period of the external trigger signal should be adjusted to the triggered measurement sequence.
If the analyzer receives a trigger event while the last sequence is still running, the trigger event is skipped
and a message Trigger event missed is displayed.
Remote control:
TRIGger[:SEQuence]:SOURce EXTernal
TRIGger[:SEQuence]:SLOPe
Pulse Gen
In Pulse Gen trigger mode the measurement is triggered by the internal pulse generator signals. The
pulse generator trigger must be enabled explicitly when the pulse generator is used for pulsed
measurements. The trigger is unavailable while the pulse generator is turned off.
Selecting Pulse Gen opens a dialog to select whether the rising or the falling edge of the Sync signal (Gen
2) or of the Pulse generator signal (Gen 1) provides the trigger event.
The propagation time of the Pulse Gen Trigger signal delays the start of the measurement. For an
R&S ZVA24 which is connected to an R&S ZVAX24 extension unit, data acquisition starts approx. 150 ns
after the rising edge of the RF signal.
Remote control:
TRIGger[:SEQuence]:SOURce PGENerator
TRIGger[:SEQuence]:PULSe
Periodic
In Periodic trigger mode the measurement is triggered by the periodic signal of an internal clock generator.
Selecting Periodic opens the numeric entry bar to select the trigger period.
The minimum trigger period that can be set corresponds to the estimated duration of the triggered
measurement sequence.
