7.1.2.4 Switching the Screen Display On and Off
In the default setting, all remote control commands are carried out with the screen display
switched off in order to attain optimum measurement speed. During the development phase
of remote control programs, however, the screen display is required in order to visually check
both the programming of the settings and the measurement results.
The following examples show functions that switch the screen display on or off during remote
control.
REM ------------ Switching on the screen display --------------------------
Public SUB DisplayOn()
Dim status As ViStatus
Dim retCnt As Long
status = viWrite(analyzer, "SYST:DISP:UPD ON", 16, retCnt)
'Switch on screen display
END SUB
REM************************************************************************
REM ------------ Switching off the screen display -------------------------
Public SUB DisplayOff()
Dim status As ViStatus
Dim retCnt As Long
status = viWrite(analyzer, "SYST:DISP:UPD OFF", 17, retCnt)
'Switch off screen display
END SUB

7.1.2.5 Configuring the Power Save Function for the Display
During remote operation, it is often unnecessary to display the measurement results on
screen. Although the
SYSTem:DISPlay:UPDate OFF
command switches off the display of
the measurement results, thus significantly improving speed during remote control, the display
itself and the background lighting in particular remain switched on.
If you also want to switch off the display itself, you must use the Power Save function by setting
the response time in minutes prior to activation.
REM -------- Switching on Power Save function -------------------------------
Public SUB PowerSave()
Dim status As ViStatus
Dim retCnt As Long
status = viWrite(analyzer, "DISP:PSAV:HOLD 1", 16, retCnt)
'Set response time to 1 minute
status = viWrite(analyzer, "DISP:PSAV ON", 12, retCnt)
'Switch on Power Save function
END SUB

The display will be immediately reactivated if you press a key on the
instrument's front panel.
