used as a source for mask counting
Math Command Group
You u se the commands in the Math Command Group to create and deļ¬ne
math waveforms. You can deļ¬ne and display up to eight math waveforms
simultaneously. You use the available math functions, such as integration,
differentiation, square root, and natural logs, to deļ¬ne your math waveform.
Math expressions can be simple, such as C1, which speciļ¬es that a waveform
should show the signal source of channel 1 with no mathematical computation.
Math expressions can a lso be complex, consisting of 100 plus characters and
comprising many sources, functions, and operators.
Math expressions require at least one source waveform. When the acquisition of a
live waveform stops, so does the acquisition of any math waveforms using that
waveform as a source. When a live waveform update or reference waveform is
altered, math waveforms containing those waveforms as sources are also updated
