Features and Functions
To Secure the Instrument for Calibration
You can secure the instrument either from the front panel or over the
remote interface. The instrument is secured when 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
secure it from the remote interface.
Front Panel Operation: Utility > CALIBRATE > SECURE
Remote Interface Operation:
To secure the instrument, send the following
command (the factory security code is shown).
CAL:SECURE:STATE ON,AT34980
To Change the Security Code
To change the security code, you must first unsecure the instrument,
and then enter a new code. Make sure you have read the security code
rules described on
page 95 before attempting to change the security code.
Front Panel Operation: Utility > CALIBRATE > SET CAL CODE
To change the security code, unsecure the instrument using the old
security code. Then go back into the menu and change the code.
Changing the code from the front panel also changes the security code
as seen from the remote interface.
Remote Interface Operation:
To change the security code, unsecure the
instrument using the old security code. Then enter the new code as
shown below.
CAL:SECURE:STATE OFF,AT34980
CAL:SECURE:CODE SN123456789
Unsecure with old code
