NOTE
Front panel control of this feature is not available on PSG E8257N instruments (unless
Option 340 is installed), or on E82x7C instruments with firmware revisions earlier than
C.03.76. The feature can be activated remotely, however, using SCPI commands. Refer
to the “System Commands” chapter of the instrument’s SCPI Command Reference for
more information.
This function prevents unauthorized personnel from reading the instrument display or tampering with the
current configuration via the front panel. When Secure Display is active, the display is blank, except for an
advisory message, as shown in Figure 8-1 below. All front panel keys are disabled.
To set Secure Display, press: Utility > Display > More > Activate Secure Display > Confirm Secure Display
Once Secure Display has been activated, the power must be cycled to re-enable the display and front panel
keys.
