4.7.4.3 Generator Setup Files
For each signal generator type to be controlled by the R&S FSW a generator setup file
must be configured and stored on the R&S FSW. The setup file defines the frequency
and power ranges supported by the generator, as well as information required for com-
munication. For the signal generators listed in chapter 4.7.4.2, "Overview of Genera-
tors Supported by the R&S FSW-B10 Option", on page 38, default setup files are provi-
ded. If necessary, these files can be edited or duplicated for varying measurement set-
ups or other instruments.
The existing setup files can be displayed in an editor in read-only mode directly from
the "External Generator" configuration dialog box. From there, they can be edited and
stored under a different name, and are then available on the R&S FSW.
(For details see the R&S FSW User Manual).
4.7.4.4 Calibration Mechanism
A common measurement setup includes a signal generator, a device under test (DUT),
and a signal and spectrum analyzer. Therefore, it is useful to measure the attenuation
or gain caused by the cables and connectors from the signal generator and the signal
analyzer in advance. The known level offsets can then be removed from the measure-
ment results in order to obtain accurate information on the DUT.
Calculating the difference between the currently measured power and a reference
trace is referred to as calibration. Thus, the measurement results from the controlled
external generator - including the inherent distortions - can be used as a reference
trace to calibrate the measurement setup.
The inherent frequency and power level distortions can be determined by connecting
the R&S FSW to the signal generator. The R&S FSW sends a predefined list of fre-
quencies to the signal generator (see also chapter 4.7.4.7, "Coupling the Frequencies",
