24 System
If a configuration back-up file is not available, obtain the License Key information saved in
the “Preliminary Procedure (Non-secure Area)" on page 506. The option numbers listed in
the License Key information allow you to determine which options were previously loaded
in the instrument and allow you to check the appropriate boxes in the update program. The
actual License Keys are needed to enable the options once the firmware is re-installed.
Service
These functions are used only for servicing the N8201A. A password is required to access
them. Refer to the Service Guide for more information.
Key Path: System
Keyboard Lock (Remote Command Only)
Disables the instrument keyboard to prevent local input when the instrument is controlled
remotely. An annunciator reading “Klock” alerts the local user that the keyboard is locked.
Or you can display a system message using SYSTem:MESSage.
Remote Command:
:SYSTem:KLOCK?
Example:
SYST:KLOCK?
Remote Message
Enables a remote user to send a message that will appear in the Status Bar at bottom of the
instrument display. The new message will overwrite any previous message. The message
will remain until removed by use of :SYSTem:MESSage:OFF.
Example: :SYSTem:MESSage "Instrument currently in use
remotely by Ted in R+D"
Remarks: The message appears as green text against a black background, to
differentiate it from internally generated messages, which appear as white text against a
black background.
The SYSTem:KLOCk command locks out the front-panel keys.
Remote Command:
:SYSTem:MESSage <string>
