Sampling oscilloscope concepts
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 waveform. 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 rapid 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-speci
fi
ed number of acquisitions. Use
Average mode to reduce random noise.
