Overview To define a math waveform
Prerequisites 1. All channel and reference Waveforms and automatic
measurement scalars that you will use in your math
waveform must be available (channels and references
contain data, measurement scalars are defined, and so
on).

Use the procedure that follows when defining a math waveform. Remember, to
ensure that the sources you use exist. Acquisitions should be running or the
channels should already be on, and reference waveform sources should contain
saved waveforms, and so on. These sources do not have to be displayed to be
used.
