74 Agilent E1441A SCPI Command Reference
Chapter 3
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.
