Operations on Math Waveforms
This instrument supports many of the same operations that it provides for
channel (live) and reference waveforms. For example, you can measure math
waveforms with cursors. This section introduces these operations:
H Vertical display scaling and positioning
H Taking automatic measurements
H Taking cursor measurements
Use math waveform operation, such as those listed above, to enhance the
displaying, processing, and analyzing of math waveforms. For example, in
addition to the operations listed, you can save math waveforms as references and
make them the source of either of two onboard waveform data bases.
Some operations allowed on channel waveforms are not allowed on math
waveforms:
H Independent horizontal scaling. Each math waveform that you create derives
its horizontal scale and position from the sources you include in its math
expression. Horizontal controls will not operate with math waveforms.
