R&S FSMR Calibration

Recording the Correction Data of R&S FSMR – CAL Key
The R&S FSMR obtains its high measurement accuracy through its inbuitl self-alignment method.
The correction data and characteristics required for the alignment are determined
by comparison of the
results at different settings with the known characteristics of the high-precision calibration signal source
of R&S FSMR at 128 MHz. The correction data are then available in the instrument as a file and can be
displayed by means of the
CAL RESULTS softkey.
For service purposes the use of
correction data can be deactivated by means of the CAL CORR
ON/OFF softkey. If the correction data recording is aborted, the last complete correction data set is
restored.
The term "Calibration" formerly used for the integrated self alignment was often
mistaken for the "true" calibration of the instrument at the test set in production and in
service. It is therefore no longer used although it appears in the abbreviated form in
the name of keys ("CAL...").

The CAL TOTAL softkey starts the recording of correction data of the
instrument.
If the correction data recording has failed or if the correction values are
deactivated (
