Trigger Source
The trigger settings define the beginning of a measurement.
Trigger Source ← Trigger Source
Selects the trigger source. If a trigger source other than "Free Run" is set, "TRG" is dis-
played in the channel bar and the trigger source is indicated.
Remote command:
TRIGger[:SEQuence]:SOURce
on page 187
Free Run ← Trigger Source ← Trigger Source
No trigger source is considered. Data acquisition is started manually or automatically
and continues until stopped explicitly.
Remote command:
TRIG:SOUR IMM
, see
TRIGger[:SEQuence]:SOURce
on page 187
External Trigger 1/2 ← Trigger Source ← 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 74).
Note: The "External Trigger 1" softkey automatically selects the trigger signal from the
Trigger 1 Input / Output connector on the front panel.
In the I/Q Analyzer application, only "External Trigger 1" is supported.
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
(See the R&S
FSV/A User Manual).
Remote command:
TRIG:SOUR EXT
,
TRIG:SOUR EXT2

TRIGger[:SEQuence]:SOURce
on page 187
IF Power ← Trigger Source ← Trigger Source
The R&S FSV/A starts capturing data as soon as the trigger level is exceeded around
the third intermediate frequency.
For frequency sweeps, the third IF represents the start frequency. The trigger band-
width at the third IF depends on the RBW and sweep type.
