R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
CAL CORR
(ON OFF)
YIG CORR
(ON OFF)
The CAL CORR (ON OFF) softkey switches the calibration data on/off.
Analyzer Mode
• ON: The status message depends upon the results of the total calibration.
• OFF: The message UNCAL appears in the status line.
Remote command: CAL:STAT ON
The YIG CORR (ON OFF) softkey switches on or off the automatic, cyclic correction
of the temperature-dependent frequency drift of the YIG filter.
The YIG CORR (ON OFF) softkey is available only on models with a frequency
range ≥ 3 GHz and ≤ 40 GHz.
When switched to ON (default setting), it is checked once per minute whether a frequency
correction for the YIG filter is required. Frequency correction is performed if
the temperature has changed by more than 3K relative to the last instance of correction.
If the instrument is operated in a temperature-controlled environment, the cyclic
frequency drift correction can – for time-critical applications – be switched off after
an operating period of ≥ 30 minutes.
Remote command: CORR:YIG:TEMP:AUTO ON | OFF
CAL RESULTS The CAL RESULTS softkey calls the CALIBRATION RESULTS table, which shows
the correction data found during calibration.
The CALIBRATION RESULTS table contains the following information:
– date and time of last record of correction values
– overall results of correction value record
– list of found correction values according to function/module
The results have the following meaning:
PASSED calibration successful without any restrictions
CHECK deviation of correction value larger than expected, correction
could however be performed
FAILED deviations of correction value too large, no correction was possible.
The found correction data are not valid.
ABORTED calibration aborted
