Commands Listed in Alphabetical Order
SELect:CH<x>
Turns the display of the channel <x> waveform on or off, where <x > is the
channel number. This command also resets the acquisition. The query returns
whether the channel is on or off but does not indicate whether it is the selected
waveform.

Syntax
SELect:CH<x> {ON|OFF|<NR1>}
SELect:CH<x>?
Arguments
ON
turns on the display of the speci fi ed waveform. This waveform also becomes
the selected waveform.
OFF
turns off the display of the speci fi ed waveform.
<NR1>
= 0 turns off the display of the speci fi ed waveform; any other value turns
on the display of the speci fi ed waveform.
Examples
SELECT:CH2 ON
turns the channel 2 waveform display on, and selects channel 2.
SELECT:CH1?
might return
:SELECT:CH1 1
indicating that channel 1 is being
displayed.
SELect:CONTROl
Sets or returns the waveform that is the recipient of future channel-related
commands, for example, the cursor commands. The command form also performs
the equivalent of a
SELect:CH<x> ON command, as well as the Math, Reference,
and Bus variations of that command.
