Math waveform elements
You can create Math waveforms from the following:
â–
Channel waveforms
â–
Reference waveforms
â–
Measurement scalars (automated measurements) that measure channel, reference, or math waveforms, or histograms.
â–
Other math waveforms
â–
Variables
â–
Filters
Dependencies
In general, math waveforms that include sources as operands are affected by updates to those sources:
â–
Shifts in amplitude or DC level of input sources that cause the source to clip also clip the waveform data supplied to the
math waveform.
â–
Changes to the vertical offset setting for a channel source that clips its data also clips the waveform data supplied to the
math waveform.
â–
Changes to the acquisition mode globally affects all input channel sources, modifying any math waveforms using them. For
example, with the acquisition mode set to Envelope, a Ch1 + Ch2 math waveform will receive enveloped channel 1 and
channel 2 data, and will also be an envelope waveform.
â–
Clearing the data in a waveform source causes a baseline (ground) to be delivered to any math waveform that includes that
source until the source receives new data.
