Acquisition mode concepts
The acquisition mode sets how the oscilloscope uses the sampled data points in each acquisition interval to create and
display a waveform. You can set the acquisition mode to one of the following modes.
Sample mode retains and uses the fi rst
sampled point from each acquisition interval
to create the displayed w aveform. This is the
default mode.
Peak Detect mode uses the highest and
lowest of all the samples contained in two
consecutive acquisition intervals. Use this
mode to help detect short r apid transitions in
a waveform.Peak Detect is not available at
faster time per division settings.
Hi Res mode oversamples lower-frequency
signals and calculates the average of all the
samples for each acquisition interval. Use
Hi Res mode to provide higher-resolution
(16-bit) sample points for lower-frequency
waveforms.
Average mode calculates and displays the
average value for each sample point over a
user-specified number of acquisitions. Use
Average mode to reduce random noise.
