:DISPlay Subsystem
This subsystem controls the selection and presentation of textual
information on the Counter’s display. This information includes
measurement results. :DISPlay is independent of, and does not modify,
how data is returned to the controller.
See the section titled “Programming the Counter to Display Results” on
Page 3-46 of this guide.
COMMAND :DISPlay[:WINDow]:BACKground[:STATe] . . . <Boolean>
Turns the display backlight ON or OFF.
QUERY RESPONSE • Single ASCII-encoded byte, 0 or 1.
• A value of 0 indicates OFF; a value of 1 indicates ON.
COMMENTS • *RST: ON
• Turning the display backlight OFF conserves battery power (if the
Counter has the Battery option).
• If the Counter is operating from battery power (Battery option required),
the display backlight is automatically turned off after a period of
inactivity. When activity is subsequently detected (a measurable signal
is applied, a front-panel key is pressed, or a setting is changed by a
command sent over the GPIB or the RS-232 interface), the display
backlight is restored to its previous state (i.e., if the backlight was set
to OFF, it remains off; if the backlight was set to ON, it is turned on).
