CAL CORR
(ON OFF) The CAL CORR (ON OFF) softkey switches the calibration data on/off.
• 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
YIG CORR
(ON OFF) The YIG CORR (ON OFF) softkey switches on or off the automatic, cyclic correction
of the temperature-dependent frequency drift of the YIG filter.
When switched to ON (default setting), it is checked once per minute whether a fre-
quency 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 correc-
tion.
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:
The YIG CORR (ON OFF) softkey is available only on models with a frequency
range
≥
3 GHz and
≤
40 GHz.
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.
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 possi-
ble. The found correction data are not valid.
