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 123
Free Run ← Trigger Source
No trigger source is considered. Data acquisition is started manually or automatically
and continues until stopped explicitly.
In its default state, the R&S FSWP performs free run measurements.
Remote command:
TRIG:SOUR IMM, see TRIGger[:SEQuence]:SOURce on page 123
Ext. 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.
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 FSWP Getting Started man-
ual.
"External Trigger 1"
Trigger signal from the TRIGGER 1 INPUT / OUTPUT connector.
(front panel)
"External Trigger 2"
Trigger signal from the TRIGGER 2 INPUT / OUTPUT connector.
(rear panel)
Note: Connector must be configured for "Input" in the "Output" config-
uration
(See the R&S FSWP User Manual).
Remote command:
TRIG:SOUR EXT, TRIG:SOUR EXT2
See TRIGger[:SEQuence]:SOURce on page 123
IF Power ← Trigger Source
The R&S FSWP 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.
For measurements on a fixed frequency (e.g. zero span or I/Q measurements), the
third IF represents the center frequency.
This trigger source is only available for RF input.
