processing speed for example). You can also write a message of up to 13
characters to the front-panel display.
Note The display cannot be turned off from the front-panel.

When the display is turned off, the entire front-panel display goes
blank except for the ADRS and RMT annunciators (the ERROR
annunciator will also be on if there are errors), and all keys except
Local are locked.

If the display is turned off, pressing Local causes the instrument to
return to local operation, the display will be turned back on.

The display is automatically turned on when power is cycled, or after
a *RST command.

to display on the front-panel from the remote interface. If you attempt
to send more than 13 characters, only the first 13 characters can be
displayed. The characters can be letters (A-Z), numbers (0-9), and
some special characters (“ ‘ space ( ) * + - , . : ; / \).
