Oscilloscope Reference Math waveform sources
Math waveform sources
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

Dependencies
In general, math waveforms that include sources as operands are affected by updates to those sources:
Shifts i
n amplitude or DC level of input sources that cause the source to clip also clip the waveform
data supplied to the math waveform.
Change
s to the vertical offset setting for a channel source that clip its data also clip the waveform
data supplied to the math waveform.
Chang
es 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.
