Command groups
Math command group
Use the commands in the Math Command Group to create and de
fi
ne math
waveforms. Use the available math functions to de
fi
ne your math waveform.
The math waveform you create depends on sources listed in the math expression.
If you change these sources, the math waveforms you previously de
fi
ned will be
affected.
Math expressions can be simple, containing no mathematical computation, such
as CH1, which speci
fi
es that a waveform shows the signal source of channel 1.
Math expressions can also be complex, consisting of 100 plus characters and
comprising many sources, functions, and operands.
The acquisition of a live waveform can stop for several reasons: You can turn off
the channel, stop the waveform (via Run/Stop from the Horiz/Acq menu), or stop
the trigger (via Run/Stop from the Trig menu). When you turn off the channel,
math continues and data is acquired but is not displayed. When you stop either the
waveform or the trigger, the math calculation stops, and the last math calculation
performed is displayed.
When a live waveform updates or a reference waveform is altered, math
waveforms containing those waveforms as sources are also updated to re
fl
ect the
changes. Also, sources must exist but do not need to be displayed to be used in
and to update math waveforms.
NOTE.
Math commands are present once a math has been added.
