Creating and Using Math Waveforms
3- 188
CSA7000 Series, TDS7000 Series, & TDS6000 S eries Instruments User Manual
H Measurements—Meas1 -- Meas8 are allowed in a math definition, but not
measurement functions, such as rise (Ch1).
CSA7000 Series & TDS 7000 Series:
H Fast Acquisition—Math is not allowed in Fast Acquisition mode.
H Roll Mode—Math is updated when acquisition is stopped.
The following topics provide details that can help you create the math waveform
that best supports your data-analysis tasks.
How to Create. You create math waveforms when you create a math expression.
You do so by applying numerical constants, math operators and functions to
operands, which can be channel waveforms, reference waveforms, math
waveforms, or measurements (scalars). You can display and manipulate these
derived math waveforms much like you can the channel and reference wave-
forms (see Operations on Math Waveforms on page 3--197).
Some examples of typical math waveforms follow:
