Trg/Gate Source
Opens the "Trigger/Gate Source" dialog box to select the trigger/gate mode.
As gate modes, all modes except "Power Sensor" are available. For details see also
Chapter 6.2.8.3, "Using Gated Sweep Operation", on page 381.
The default setting is "Free Run". If a trigger mode other than "Free Run" has been set,
the enhancement label "TRG" is displayed and the trigger source is indicated.
Note: When triggering or gating is activated, the squelch funciton is automatically dis-
abled (see "Squelch" on page 421).
Remote command:
TRIGger<n>[:SEQuence]:SOURce on page 839
[SENSe:]SWEep:EGATe:SOURce on page 842

The start of a sweep is not triggered. Once a measurement is completed, another is
started immediately.
