Use the procedure that follows when defining a math waveform. Remember, you
should first ensure that the sources you use exist. C hannel sources will be
acquired when used in a math expression, reference waveform sources should
contain saved waveforms, and so on. These sources do not have to be displayed
to be used.
Overview To define a math waveform Related control elements & resources
Prerequisites 1. All channel and reference waveforms and automatic
measurement scalars that you wil l use i n your math
waveform must be available (channels and references
contain data, measurement scalars are defined, and so
on.)
Note. I f y ou use a channel that is not acquiring,
including it in a math wavef orm t hat you turn on will
implicitly cause it to be acquired.

module installat ion. See page 3--24 for acquisi tion
setup and page 3--48 for trigger setup in this
