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

7.1.3 Sending Simple Instrument Setting Commands
This example shows how the center frequency, span and reference level of the instrument are
set.
REM -------- Instrument setting commands ----------------------------------
PUBLIC SUB SimpleSettings()
Dim status As ViStatus
Dim retCnt As Long
status = viWrite(analyzer, "FREQENCY:CENTER 128MHz", 22, retCnt)
'Center frequency 128 MHz
status = viWrite(analyzer, "FREQENCY:SPAN 10MHZ", 19, retCnt)
'Set span to 10 MHz
status = viWrite(analyzer, "DISPLAY:TRACE:Y:RLEVEL -10dBm", 29, retCnt)
'Set reference level to -10dBm
END SUB

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