Syntax
SELect{:MATH|
: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.
Examples
SELECT:MATH ON turns the math waveform display on, and selects it.
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.
