CALibration:SECurity:STATe
Syntax
CALibration:SECurity:STATe {OFF | ON}, <code>
CALibration:SECurity:STATe?
Description
This command unsecures or secures the instrument for calibration. To unsecure the instrument, you must
provide a security code to prevent accidental or unauthorized calibrations of the instrument. Before you
can calibrate the instrument, you must unsecure it by entering the correct security code.
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.
Parameters
Name Type Range of Values Default Value
<code> Unquoted ASCII
String
A string of up to 12 characters. You do not have
to use all 12 characters but the first character
must always be a letter (A-Z). The remaining 11
characters can be letters, numbers (0-9), or the
underscore character ("_"). Blank spaces are not
allowed.
This parameter is required to dis-
able security, but is optional to
enable security (but must be cor-
rect if provided).
Remarks
l Once you enter a security code, that code must be used for both front-panel and remote-interface cal-
ibration. For example, if you secure the instrument from the front panel, you must use that same code
to unsecure it from the remote interface.
l Unsecuring the instrument using this command enables the instrument to be calibrated.
l
Changing the instrument's calibration secure state using this command does not increment the cal-
ibration count (CALibration:COUNt? command).
l To calibrate the Keysight 53220A/230A, use the CALibration:VALue and CALibration? commands.
l The calibration security setting 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 com-
mand).
Return Format
The query returns the current calibration security setting: 0 (OFF) or 1 (ON).
