Agilent Technologies Agilent 33500 Series

CALibration Subsystem
Parameter Typical Return
Return the calibration count:
CAL:COUN?
l Because the value increments for each calibration point (each CALibration:ALL?), a complete calibration adds
many counts.
l Can display count regardless of whether instrument is secured.
l This setting is non-volatile; it will not be changed by power cycling or *RST.
CALibration:SECure:CODE <new_code>
Sets the security code to prevent unauthorized calibrations.
Parameter Typical Return
Unquotedstringupto12characters
Must start with letter (A-Z)
May contain letters, numbers (0-9) and underscores
(none)
Set new security code:
CAL:SEC:CODE MY_CODE_272
l When shipped from the factory, the instrument is secured, with the security code set to AT33520A for the
33521A and 33522A, or AT33500 for other 33500 Series instruments.
l To change code: unsecure calibration memory with old code, then set new code.
l If you forget the security code, see Unsecure Instrument Without Security Code.
l This setting is non-volatile; it will not be changed by power cycling or *RST.
CALibration:SECure:STATe {ON|1|OFF|0} [,<code>]
CALibration:SECure:STATe?
Unsecures or secures the instrument for calibration. To calibrate, you must unsecure the instrument with the code
(CALibration:SECure:CODE).
Parameter Typical Return
{ON|1|OFF|0}, default ON

Secure calibration:

l <code> is optional to secure the instrument, but must be correct if provided.
l Front panel and remote interface calibration use same code. If you secure the instrument from one interface, use
