To Change the Security Code To change the security code, you must
first unsecure the waveform generator, and then enter a new code.
Make sure you have read the security code rules described on page 190
before attempting to change the security code.
• Front-Panel Operation : To change the security code, unsecure the
waveform generator using the old security code. Then press ,
Calibrate
and
Secure 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, you must
first unsecure the waveform generator using the old security code.
Then enter the new code as shown below.
CAL:SECURE:STATE OFF, AT33520A
Unsecure with old code
CAL:SECURE:CODE NEWCALCODE
Enter new code
Calibration Count
You can query the waveform generator to determine how many
calibrations have been performed. Your waveform generator was
calibrated before it left the factory. When you receive your waveform
generator, be sure to read the count to determine its initial value.
• The calibration count is stored in non-volatile memory and does not
change when power has been off or after a remote interface reset.
• The calibration count increments up to a maximum of more than
4 billion (2
32
-1). Since the value increments by one for each
calibration point that stores a value, a complete calibration may
increase the value by many counts.
• Front-Panel Operation : Press and
