Math Command Group
Use the commands in the Math Command Group to create and define math
waveforms. You can define and display up to four math waveforms simultaneously
on four channel models and up to two on two channel models. Use the available
math functions to define your math waveform.
The math waveform you create depe nds on sources listed in the math expression.
If you change these sources, the math waveforms you previously defined will be
affected.
Math expressions can be simple, containing no mathematical computation, such
as CH1, which specifies that a w aveform shows the signal source of channel 1.
Math expressions can also be complex, consisting of 100 plus cha racters 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), o r 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 update or reference waveform is altered, math waveforms
containing those w aveforms as sources are also updated to reflect the changes.
Also, sources must exist but do not need to be displayed to be used in and to
update math waveforms.
