If the waveform is not displayed, click Display.
Set scale and position
4. Click Position and Scale, and use the multipurpose knobs or
pop-up keypad to size and position the waveform on the
screen.
Keep in mind the following:
ƒ
The position is in divisions, so changing the scale can
make the math waveform disappear until position is
also changed (the same effect happens with channel
waveforms).
ƒ
You can click and drag a waveform handle to change
the waveform vertical position.
ƒ
You can change the waveform vertical position and
scale by clicking on the waveform handle and using the
multipurpose knobs to adjust.
ƒ
You cannot adjust the offset of a math waveform.
ƒ
You cannot adjust horizontal scale, position, and
sample density (resolution) of math waveforms;
different length source waveforms result in a math
waveform of the shortest source record length. If you
adjust these settings for sources of a math waveform,
the adjustments are reflected in the math waveform.
