Switching the Screen Display On and Off
In the default setting, all remote control commands are carried out with the screen dis-
play switched off in order to attain optimum measurement speed. During the develop-

The following examples show functions with which the screen display can be switched
on or off during remote control operation.
REM ------------ Switching on the screen display ---------------------------
Public SUB DisplayOn()
CALL InstrWrite(analyzer, "SYST:DISP:UPD ON")
'Switch on screen display
