Defeating Calibration Security
If the calibration security code is unknown, the security feature can be
defeated by disassembling the AFG and moving the jumper on connector
J104 (see Figure 3-1) to the unsecured position (left-most pins). To prevent
accidental or unauthorized calibration, move the jumper back to the secured
position (right-most pins) as soon as the security code has been set to the
desired value (use the CALibration:SECure:CODE <code> command).
Disassembly instructions can be found in Chapter 5.
