"External Trigger 2"
Trigger signal from the TRIGGER 2 INPUT/OUTPUT connector on
the front panel.
Note: Connector must be configured for "Input" in the "Outputs" con-
figuration (see
"Trigger 2/3" on page 100).
"External Trigger 3"
Trigger signal from the TRIGGER 3 INPUT/ OUTPUT connector on
the rear panel.
Note: Connector must be configured for "Input" in the "Outputs" con-
figuration (see
"Trigger 2/3" on page 100).

I/Q Power ← Trigger Source
This trigger source is not available if the optional Digital Baseband Interface
(R&S
FSW-B17) or Analog Baseband Interface (R&S FSW-B71) is used for input. It is
also not available for analysis bandwidths
≥
160 MHz.
Triggers the measurement when the magnitude of the sampled I/Q data exceeds the
trigger threshold.
The trigger bandwidth corresponds to the resolution bandwidth setting for data acquisi-
tion (see
chapter 5.6, "Data Acquisition" , on page 101).

IF Power ← Trigger Source
The R&S FSW starts capturing data as soon as the trigger level is exceeded around
the third intermediate frequency.
This trigger source is only available for RF input.
It is not available for input from the Digital Baseband Interface (R&S FSW-B17) or the
Analog Baseband Interface (R&S FSW-B71).
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.
The available trigger levels depend on the RF attenuation and preamplification. A refer-
ence level offset, if defined, is also considered.
For details on available trigger levels and trigger bandwidths see the data sheet.

Baseband Power ← Trigger Source
Defines triggering on the baseband power (for baseband input via the Digital Baseband
Interface R&S
FSW-B17 or the Analog Baseband interface R&S FSW-B71)).
