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).
