Color Meaning
Green Active correction settings valid and in use
Yellow For Spectrum mode only:
Correction settings active, but not all frequencies in measurement
span are covered by filter, or the combined filter does not cover any
frequencies.
Use the [SENSe:]CORRection:FRESponse<si>:USER:
SCOVered? command to determine the covered span.
Red Correction settings active, but not in use, e.g. due to invalid settings
(see
"Correction filters for I/Q data" on page 726)
Remote command:
[SENSe:]CORRection:FRESponse<si>:USER:VALid?
on page 1318
Since multiple correction settings can be active at the same time, the channel bar
merely indicates that frequency response correction is being applied, but not which
files are being used. To find out which correction files are being used for the active
application, open the "User-Defined Frequency Response Correction" dialog box (see
Chapter 10.6.2, "User-defined frequency response correction settings" , on page 728).
An LED-like symbol indicates whether each file is active and user correction or the
external preamplifier in general is switched on (symbol "lights up") or not (symbol is
dark). A purple symbol represents a Touchstone file. A green symbol represents a fre-
quency response (
.fres
) file.
Storing frequency response correction settings
You can store frequency response correction settings to a file (saveset) and load them
for future measurements. For details see
"Save Settings" on page 731.
Storing SaveSets with a loaded Touchstone file
If you store the settings for a measurement using a Touchstone file in a saveset, only
the link to the Touchstone file name is actually stored. That means that if you change
the settings in the file and recall the saveset for the measurement later, the results will
differ from the original measurement.
Imported I/Q data
Correction factors are not applied to input from I/Q data files during import. Data from
these files is imported as it was stored. However, if any correction factors were applied
to the stored data, for example from Touchstone files, the imported data contains those
corrections.
Restrictions
Currently, the R&S FSV/A has the following restrictions for Touchstone file support:
●
Trace data containing corrections from Touchstone files cannot be returned in I/Q
block format
