SELect:CONTRO
l:SELect:CONTROl:SELect:D<0-15>
SELect:D<x>
Arguments
This command takes a Boolean argument, which means it can be used to either
turn all digital channels on or all digital channels off.
Examples
SELect:DAll 1 turns on all digital channels.
SELect:D<x>
Turns on the display of the digital channel <x> and resets the acquisition. <x > is
the channel number, which can be 0–15. The query returns whether the channelis
on or off but does not indicate whether it is the selected waveform.

Syntax
SELect:D<x> {<NR1>|OFF| ON}
SELect:D<x>?
Arguments
ON turns on the display of the specified waveform. This waveform also becomes
the selected waveform.
OFF turns off the display of the specified waveform.
<NR1> = 0 turns off the display of the specified waveform; any other value turns
on the display of the specified waveform.
Examples
SELECT:D2 ON turns the digital channel 2 waveform display on, and selects
digital channel 2.
SELECT:D2? might return : SELECT:D2 1 indicating that digital channel 2 is
being displayed.
SELect{:MATH|:MATH1}
Turns on and off the display of the math waveform. The query returns whether
the math waveform is on or off but does not indicate whether it is the selected
waveform.

:MATH1} { ON|OFF|<NR1>}
SELect{:MATH|:MATH1}?
Arguments
ON turns on the display of the specified waveform. This waveform also becomes
the selected waveform.
OFF turns off the display of the specified waveform.
<NR1> = 0 turns off the display of the specified waveform; any other value turns
on the display of the specified waveform.

SELECT:MATH? might return :SELECT:MATH 1 indicating that the math
waveform is being displayed.
SELect:REF<x>
Turns on and off the display of the reference waveform <x>. The <x > variable
represents the reference channel number, which can be 1–4. The query returns
whether the channel is on or off.

<NR1> = 0 turns off the display of the specified waveform; any other value turns
on the display of the specified waveform.
Examples
SELECT:REF2 ON turns the channel 2 waveform display on, and selects reference
waveform 2.
SELECT:REF2? might return :SELECT:REF 2 1 indicating that reference
waveform 2 is being displayed.
