Calibration Overview
This section gives a brief introduction to the calibration features of the
function generator. For a more detailed discussion of the calibration
procedures, see chapter 4 in the Keysight 33210A Service Guide.
Calibration Security
This feature allows you to enter a security code to prevent accidental or
unauthorized calibrations of the function generator. When you first
receive your function generator, it is secured. Before you can perform a
calibration, you must unsecure the function generator by entering the
correct security code.
• The security code is set to “AT33210A” 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 may contain up to 12 alphanumeric characters.
The first character must be a letter, but the remaining characters can
be letters, numbers, or an underscore (“ _ ”). You do not have to use
all 12 characters but the first character must always be a letter.
If you forget your security code, you can disable the security feature by
means of two “CAL ENABLE” pads on the main PC board inside the
instrument. See the Keysight 33210A Service Guide for more information.
