you do, the Math1 definition is rejected with an error because a circular definition is not
allowed.
 Fast Acquisitions: Math is not allowed in Fast Acquisitions mode.
 Roll Mode: Math is not allowed in roll mode until you push STOP.
 Different Length Sources: If you use two waveforms (channel and reference waveforms) of
different lengths, the length of the math waveform will be the shorter of the two lengths.
Creating Math Waveforms
You create math waveforms when you create a math expression. You do so by applying numerical
constants, math operators and functions to operands (see Sources on page 264). You can display
and manipulate these derived math waveforms much like you can the channel and reference
waveforms (see Using Math Waveforms on page 330).
Some examples of typical math waveforms follow:
To normalize this
waveform:
Enter this math
expression:
(Ch1 - Meas1)/ Meas2,
where
Ch1 is the waveform shown at left
Meas1 = Low of Ch1
Meas2 = amplitude of Ch1
And get this math
waveform:
To simulate AC
coupling on this
waveform:
Enter this expression:
Intg(Ch1-Avg(Ch1)),
where
Ch1 is the waveform shown at left
Avg is the average function
And get this math
waveform:
