To adjust the math waveform scale and offset
1 Make sure the multiplexed scale and position knobs above and below
the
[Math] key are selected for the math waveform.
If the arrow to the left of the
[Math]
key is not illuminated, press the
key.
2 Use the multiplexed scale and position knobs above and below the
[Math] key to re- size and re- position the math waveform.

Units for Math Waveforms
Units for each input channel can be set to Volts or Amps using the Units
softkey in the channel's Probe Menu. Units for math function waveforms
are:

Math Operating Hints
If the analog channel or math function is clipped (not fully displayed on screen) the
resulting displayed math function will also be clipped.
Once the function is displayed, the analog channel(s) may be turned off for better viewing
of the math waveform.
The vertical scaling and offset of each math function can be adjusted for ease of viewing
and measurement considerations.
The math function waveform can be measured using [Cursors] and/or [Meas].

Math Scale and Offset are Set Automatically
Any time the currently displayed math function definition is changed, the function is
automatically scaled for optimum vertical scale and offset. If you manually set scale and
offset for a function, select a new function, then select the original function, the original
function will be automatically rescaled.
