For gated measurements, this setting also selects the gating source.
For more information see "Trigger Source" on page 392.
Note: When triggering or gating is activated, the squelch function is automatically dis-
abled.
(See " Squelch " on page 354).
Remote command:
TRIGger[:SEQuence]:SOURce on page 911
[SENSe:]SWEep:EGATe:SOURce on page 916
Free Run ← Trigger Source
No trigger source is considered. Data acquisition is started manually or automatically
and continues until stopped explicitly.
In the Spectrum application, this is the default setting.
Remote command:
TRIG:SOUR IMM, see TRIGger[:SEQuence]:SOURce on page 911
External Trigger 1/2 ← Trigger Source
Data acquisition starts when the TTL signal fed into the specified input connector
meets or exceeds the specified trigger level.
(See " Trigger Level " on page 399).
Note: The "External Trigger 1" softkey automatically selects the trigger signal from the
Trigger 1 Input / Output connector on the front panel.
For details, see the "Instrument Tour" chapter in the R&S FSV/A Getting Started man-
ual.
"External Trigger 1"
Trigger signal from the Trigger 1 Input / Output connector.
"External Trigger 2"
Trigger signal from the Trigger 2 Input / Output connector.
Note: Connector must be configured for "Input" in the "Output" config-
uration
Remote command:
TRIG:SOUR EXT, TRIG:SOUR EXT2
See TRIGger[:SEQuence]:SOURce on page 911
SWE:EGAT:SOUR EXT for gated triggering, see [SENSe:]SWEep:EGATe:SOURce

Video ← Trigger Source
Defines triggering by the video signal, i.e. the filtered and detected version of the input
signal (the envelope of the IF signal), as displayed on the screen.
Define a trigger level from 0 % to 100 % of the diagram height. The absolute trigger
level is indicated by a horizontal trigger line in the diagram, which you can also move
graphically to change the trigger level.
A fixed hysteresis of 10 % of the specified trigger value (in V) is applied to the video
trigger level automatically and cannot be changed.
Video mode is only available in the time domain, and not for I/Q-based data.
