Example:
SYST:DISP:FPAN ON
Activates the display.
SYSTem:DISPlay:UPDate <Boolean> | ONCE
Switches the display on or off while the analyzer is in the remote state. The command has no effect while
the analyzer is in the
Local
operating state.
Switching off the display speeds up the measurement. This command may have an impact on the
update of trace and channel settings; see
SYSTem:SETTings:UPDate
.
<Boolean>
ON | OFF – Switch the display on or off. If the display is switched on, the analyzer
shows the diagrams and traces like in manual control.
ONCE
Switch the display on and show the current trace. This parameter can be used for
occasional checks of the measurement results or settings. The measurement is
continued, however, the measurement results are not updated. Compared to the ON
setting, ONCE does not slow down the measurement speed.
