a string variable with at least 50 characters).

DISPlay {OFF|ON}
DISPlay?
Disable or enable the function generator front-panel display. When it is disabled,
the front-panel display is blanked (however, the bulb used to backlight the display
remains enabled). The DISP? query returns “0” (OFF) or “1” (ON).
–
With the front-panel display disabled, there will be some improvement
in
command execution speed from the remote interface.
–
Sending a message to the front-panel display from the remote interface
(DISP:TEXT command) overrides the display state. This means that you can
display a message even if the display is disabled (remote interface errors are
always displayed even if the display is disabled).
– The display is automatically enabled when power is cycled, after an instrument
reset (*RST command), or when you return to local (front panel) operation.
Press the key or execute the IEEE-488 GTL (Go To Local) command
from the remote interface to return to the local state.
– The display state is saved when you store the instrument state using *SAV
command. When you recall the instrument state using *RCL command, the
front-panel display will return to the previous state.
f.ff = Firmware revision number
b.bb = Boot kernel revision number
