To Change the Security Code To change the security code, you must
first unsecure the function generator, and then enter a new code.
Be sure to read the security code rules on page 118 before changing the
security code.
Front-Panel Operation: To change the security code, first make sure
that the function generator is unsecured. Select the “
PARAMETER”
level of the
UNSECURED command, enter the new security code, and
then press Enter. Changing the code from the front panel also
changes the code required from the remote interface.
Remote Interface Operation:
CALibration:SECure:CODE <
new code>
To change the security code, first unsecure the function generator
using the old security code. Then, enter the new code. For example,
"CAL:SEC:STAT OFF, HP033120"
Unsecure with old code
"CAL:SEC:CODE ZZ002133" Enter new code
Calibration Count
You can determine the number of times that your function generator
has been calibrated. Your function generator was calibrated before it left
the factory. When you receive your function generator, 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 32,767 after
which it wraps-around to 0. Since the value increments by one for
each calibration point, a complete calibration will increase the value
by many counts.
