Keysight 53230A - Calibration:count

CALibration:COUNt?
Syntax
CALibration:COUNt?
Description
This query queries the instrument to determine how many calibrations have been performed. Note that
your instrument was calibrated before it left the factory. When you receive your instrument, be sure to
read the count to determine the initial values.
For a more detailed discussion of the calibration procedures, see the Keysight
53210A/53220A/53230A 350 MHz Counter Service Guide. Please refer to the Ser-
vice Guide before attempting to calibrate the instrument. Improper use of the
CALibration commands can adversely affect the accuracy and reliability of the instru-
ment.
Remarks
l The calibration counts increment up to a maximum of over four billion (2
32
- 1) after which they roll
over to "0". Since the value increments by one for each calibration point, a complete calibration may
increase the value by many counts. However, it is unlikely that the count will ever roll over due to the
high maximum.
l The calibration count is incremented by the CALibration:ALL? and CALibration:LEVel3? commands. The
calibration count is also incremented when a calibration override is performed (see the Keysight
53210A/53220A/53230A 350 MHz Counter Service Guide for more information). You can read the cal-
ibration count whether the instrument is secured or unsecured.
l The calibration count is stored in non-volatile memory, and does not change when power has been off,
after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
Return Format
The query returns the calibration count indicating how many calibrations have been performed in the
form +134.
Examples
The following example returns the calibration count.
