DISPlay {OFF|ON}
Turn the front-panel display off or on. When the display is turned off,
output parameters are not sent to the display and all annunciators
except
ERROR and Shift are disabled. Front-panel operation is otherwise
unaffected by turning off the display. [ Stored in volatile memory ]
Sending a message to the display from the remote interface overrides
the display state; this means that you can display a message even if
the display is turned off.
The display state is automatically turned on when you return to the
local (front panel) state. Press the
Shift key or execute LOCAL 710
from the remote interface to return to the local state.
DISPlay?
Query the front-panel display setting. Returns “0” (
OFF) or “1” (ON).
DISPlay:TEXT <
quoted string>
Display a message containing up to 11 characters on the front panel;
any additional characters are truncated. Commas, periods, and
semicolons share a display space with the preceding character, and are
not considered individual characters. When a message is displayed,
information relating to the output waveform (such as frequency and
amplitude) is not sent to the display. [ Stored in volatile memory ]
The DISP:TEXT command is allowed only while the function generator
is in the remote mode. An error is generated if you attempt to execute the
command while in the local mode.
The following command string shows how to display a message on the
front panel.
"DISP:TEXT ’HELLO’"
