6. In the "Trigger and Gate" dialog box, select "Signal Source" = "PSE".
The R&S FSW is configured to trigger when the defined conditions for the power
sensor occur. Power measurement results are provided as usual.
6.2.4 External Generator Control (Option R&S
FSW-B10)
If the R&S FSW External Generator Control (R&S FSW-B10) is installed, you can oper-
ate various commercially available generators as an external generator with the
R&S
FSW. Thus, scalar network analysis with the R&S FSW is possible.

6.2.4.1 About External Generator Control
A common measurement setup includes a signal generator, a device under test (DUT),
and a signal and spectrum analyzer, for example the R&S
FSW. In this setup, the sig-
nal analyzer can control which signal the generator is to send, which is in turn mea-
sured by the analyzer. This process is referred to as
external generator control . The
generator in this setup is referred to as a tracking generator .
A measurement with a tracking generator is useful to measure any effects on the
power level caused by the cables and connectors from the signal generator and the
signal analyzer in advance. The known effects can then be removed from the mea-
surement results in order to obtain accurate information on the DUT.
6.2.4.2 Basics on External Generator Control
Some background knowledge on basic terms and principles used for external genera-
tor control is provided here for a better understanding of the required configuration set-
tings.
External generator control is only available in the Spectrum, I/Q Analyzer, Analog
Demodulation and Noise Figure applications.
