IF (Wide) Out Frequency
Defines or indicates the frequency at which the IF signal level is provided at the IF/
VIDEO/DEMOD connector if IF/VIDEO/DEMOD Output is set to "IF".
Note: The IF output frequency of the IF WIDE OUTPUT connector cannot be defined
manually, but is determined automatically depending on the center frequency. It is indi-
cated in this field when the IF WIDE OUTPUT connector is used. For details on the
used frequencies see the data sheet.
The IF WIDE OUTPUT connector is used automatically instead of the IF/VIDEO/
DEMOD connector if the bandwidth extension (hardware option R&S FSW-B160 / -
U160) is activated (i.e. for bandwidths > 80 MHz).
If the IF 2 GHZ OUT output is activated, the measured IF value is provided at a fixed
frequency of 2 GHz.
For more information see chapter 6.2.1.6, "IF and Video Signal Output", on page 317.

Noise Source
Switches the supply voltage for an external noise source on or off.
External noise sources are useful when you are measuring power levels that fall below
the noise floor of the R&S FSW itself, for example when measuring the noise level of a
DUT.
For details see chapter 6.2.1.4, "Input from Noise Sources", on page 316

Trigger 2/3
Defines the usage of the variable TRIGGER INPUT/OUTPUT connectors, where:
"Trigger 2": TRIGGER INPUT/OUTPUT connector on the front panel
"Trigger 3": TRIGGER 3 INPUT/ OUTPUT connector on the rear panel
(Trigger 1 is INPUT only.)
Note: Providing trigger signals as output is described in detail in the R&S FSW User
Manual.
"Input"
The signal at the connector is used as an external trigger source by
the R&S FSW. No further trigger parameters are available for the
connector.
"Output"
The R&S FSW sends a trigger signal to the output connector to be
used by connected devices.
Further trigger parameters are available for the connector.
