: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 :SEL ECT:MATH 1 indicating that the math
