CALibration:SECure:STATe
Syntax
CALibration:SECure:STATe <mode>, <code>
CALibration:SECure:STATe?
Description
This command unsecures or secures the instrument for calibration. This feature allows you to enter 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 Agilent 34980A Service Guide. Please refer to that guide before attempting to calibrate the instrument as improper use of the CALibration commands can adversely affect the accuracy and reliability of the instrument. |
Used With:
34951A Isolated DAC Module
34952A Multifunction Module (DAC channels only)
Internal DMM

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 is a required parameter |
Remarks
When you first receive your instrument, it is secured. The security code is set to "AT34980" when the instrument is shipped from the factory.
Once you enter a security code, that code must be used for both front-panel and remote operation. For example, if you secure the instrument from the front panel, you must use that same code to unsecure it from the remote interface.
Unsecuring the instrument using this command enables all installed modules and the internal DMM to be calibrated.
To calibrate the internal DMM, use the CALibration? command.
To calibrate the 34951A Isolated DAC Module, use the CALibration:MODule? command.
To calibrate the DAC channels on the 34952A Multifunction Module, use the CALibration:BEGin[:VOLTage] and CALibration:POINt? commands.
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 command).
Return Format
The query command returns "0" (OFF) or "1" (ON) indicating the current calibration security setting.
Examples
The following command unsecures the instrument.
CAL:SEC:STAT OFF,AT34980
The following query returns the current calibration security setting.
CAL:SEC:STAT?
