Calibration Security Code

Calibration Security Code

This feature allows you to enter a security code (electronic key) to prevent accidental or unauthorized calibrations of the function generator.

When you first receive your function generator, it is secured. Before you can adjust calibration constants you must unsecure the function generator by entering the correct security code. A procedure to unsecure the function generator is given on page 47.

œThe security code is set to “HP033120” when the function generator is shipped from the factory. The security code is stored in non-volatilememory, and does not change when power has been off or after a remote interface reset.

œTo secure the function generator from the remote interface, the security code may contain up to 12 alphanumeric characters as shown below. The first character must be a letter, but the remaining characters can be letters or numbers. You do not have to use all 12 characters but the first character must always be a letter.

A _ _ _ _ _ _ _ _ _ _ _ (12 characters)

œTo secure the function generator from the remote interface but allow it to be unsecured from the front panel, use the eight-character format shown below. The first two characters must be “HP” and the remaining characters must be numbers. Only the last six characters are recognized from the front panel, but all eight characters are required. (To unsecure the function generator from the front panel, omit the “HP” and enter the remaining numbers.)

H P _ _ _ _ _ _ (8 characters)

œIf you forget your security code, you can disable the security feature by adding a jumper inside the function generator, and then entering a new code. See the procedure on the following page.
