Calibration Security

This section describes the instrument's calibration security system. If you forget the security code, you can override calibration security.

Security Overview

A security code (calibration password) prevents accidental or unauthorized instrument calibration.

• When shipped from the factory, the instrument is secured, with the security code (calibration password) set to AT3446XA.
• The same security code must be used for front panel and remote operation. If you secure the instrument from the front panel, use that same code to unsecure it from the remote interface.
• This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
• Security code rules:
  Unquoted string up to 12 characters
  Must start with letter (A-Z)
  May contain letters, numbers (0-9) and underscores
• Front Panel: [Utility] > Test / Admin > Security
  
• SCPI: CALibration:SECure:STATe
