13. Optionally, to define a constant level offset for the external generator, define a
"Source Offset".
14. The default frequency list for the calibration sweep contains 1001 values, divided in
equi-distant frequencies between the R&S
FSV/A's start and stop frequency. For
most cases, this automatic coupling should be correct. Check the "Result Fre-
quency Start" and "Result Frequency Stop" values to make sure the required mea-
surement span is covered. If necessary, change the frequency settings on the
R&S
FSV/A ([FREQ] key > "Frequency Config" softkey), or use a different genera-
tor type.
15. Switch to the "Source Calibration" subtab.
16. Select the "Source Calibration Type": "Transmission" to perform a calibration
sweep and store a reference trace for the measurement setup.
17. Select "Source Calibration Normalize": "On".
18. Optionally, shift the reference line further down in the result display by descreasing
the "Reference": "Position".
The measurement setup is now calibrated. Subsequent measurement results are
normalized, so that any unwanted effects from the cables and connectors are
removed.
To define a new generator setup file
1. Press the [INPUT/OUTPUT] key and select "External Generator Config".
2. In the "Interface Configuration" subtab, select a generator type that has similar
characteristics (frequency and power ranges).
3. Select "Edit Generator Setup File".
The configuration file for the selected generator type is displayed (read-only) in an
editor.
4. Edit the configuration values according to your generator. Be sure not to change
the syntax of the file - only change the
values
of the parameters.
Errors will only be detected and displayed when you try to use the new generator
(see also
"Displayed Information and Errors"
5. Save the file under a different name with the extension
.gen
:
a) In the editor, select "File > SaveAs".
b) Select "Save as type: All Files (*.*)".
c) Specify a name with the extension
.gen
.
6. In the R&S
FSV/A firmware, close the "External Generator Config" dialog and re-
open it.
Now you can select the new generator type from the selection list on the "Interface
Configuration" tab.
