Reference
Envelope. Use Envelope acquisition mode to capture the minimum and maximum
extremes of a signal over a specified number of acquisitions (N). The enveloped
wavefor
m data acquisition clears and then starts over after each N acquisitions. If
you push the Single Seq button, envelope acquisition stops after N acquisitions.
Use the general purpose knob to set the number of acquisitions.
Average. Use Average acquisition mode to reduce random or uncorrelated noise
in the signal you want to display. The averaged waveform is a running average
over a
specified number of acquisitions (N). If you push the Single Seq button,
average acquisition stops after N acquisitions. Use the general purpose knob to
set the number of acquisitions.
If you probe a noisy square wave signal that contains intermittent, narrow glitches,
the waveform displayed will vary depending on the acquisition mode you choose.
