Agilent Technologies E1441A user service SECure:CODE, SECure:STATe, Parameters

Comments • *RST does not change the calibration count stored in non-volatile memory.

Example Querying the number of occurrences of point calibrations:

CAL:COUN? Query the calibration count

:SECure:CODE

CALibration:SECure:CODE <new code> enters a new calibration security code. To change the security code, first unsecure the function generator using the old security code with CAL:SEC:STAT OFF, <old code>. Then, enter the new code with CAL:SEC:CODE <new code>. The calibration security code may contain up to 12 characters. The security code is stored in non-volatile memory.

Comments • The security code is set to "HP_E1441" when the function generator is shipped from the factory. The security code is stored in non-volatile memory, and does not change when power has been off or after a remote interface reset.

•The security code <new code> can contain up to 12 alphanumeric characters. The first character must be a letter. The remaining characters can be letters or numbers or an underscore. You do not have to use all 12 characters but the first character must be a letter.

•If you forget or lose the active security code, you can disable the security feature by adding a jumper inside the function generator . You then enter a new code and remove the jumper. See “Unsecuring the Function Generator (Lost Security Code)” on page 175.

Example Enter a new calibration security code:

CAL:SEC:STAT OFF, HP_E1441	Unsecure with the old code.
CAL:SEC:CODE the_new_code	Enter a new calibration code
	(a maximum of 12 characters).

:SECure:STATe

CALibration:SECure:STATe OFF ON, <code> unsecures or secures the function generator for calibration. The calibration code must be the code set by the CAL:SEC:CODE command. The state is stored in non-volatile memory.
