Math waveform elements
You can create Math waveforms from the following:
■
Channel waveforms
■
Reference waveforms
■
Measurement scalars (automated measurements) that measure channel, reference, or math waveforms, or histograms.
■
Other math waveforms
■
Variables
■
Filters
Dependencies
In general, math waveforms that include sources as operands are affected by updates to those sources:
■
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.
■
Changes to the vertical offset setting for a channel source that clips its data also clips the waveform data supplied to the
math waveform.
■
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.
■
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.
