Peak Detect m ode uses the highest
and lowest of all the samples con-
tained in two consecutive acquisition
intervals. This mode only works with
real-time, noninterpolated sampling
and is useful for catching high
frequency glitches.
Peak Detect
Hi Res mode calculates the average of
all the samples for each acquisition
interval. Hi-Res provides a higher-res-
olution, lower-bandwidth waveform.
Hi Res
Envelope mode finds the highest and
lowest record points over many
acquisitions. Envelope uses Peak
Detect for each individual acquisition.

Average mode calculates the average
value for each record point over many
acquisitions. Average uses Sample
mode for each individual acquisition.
Use average mode to reduce random
