b) Select an
.s2p
file that contains the frequency response for the used IF cable.
Make sure that the file covers the frequency range you want to measure with
the frontend.
Frequency response files are usually provided with the IF cable. The calibration
data for the IF cable provided with the R&S
FSV/A is installed on the instru-
ment at the factory.
The
.s2p
files are stored on the instrument under
C:\R_S\INSTR\USER\external_frontends\<frontend_type>\
touchstonefiles\
. For example, the files for the IF cable are stored under
C:\R_S\Instr\user\external_frontends\FE44S\
touchstonefiles\if_default_cable_1347_7552_00.s2p
.
c) Set the "Correction State" to "On" to enable the use of the correction file.
The R&S FSV/A automatically adapts the measured values from the external fron-
tend to the known cable loss.
11. Configure the measurement as usual. The amplitude and frequency settings are
adapted to the supported values of the external frontend. The reference value and
attenuation refer to the RF input of the external frontend.

Error messages
If errors occur, status messages in the external frontend configuration dialog box and in
the status bar of the display inform you about them.
Query the error message queue using the remote command
SYST:ERR?
to determine
if any or which errors occurred during operation. For details, see Chapter 13.2, "Error
