Because the instrument can only store a finite number of waveform data points, there is a trade-off
between the waveform details and the record length. You can acquire either a detailed picture of a
waveform for a shorter period of time or a less detailed picture for a longer period of time.
Acquisition Mode Control Window
Access this control window from the Horizontal/Acquisition menu Acquisition Mode command.
Overview
A single waveform data point can be made up of several sequentially
acquired data points. The waveform data points can also be created from
a composite of sampled data taken from multiple acquisitions. The
acquisition modes determine how the waveform data points are produced
from the sampled data.
To Use
Select the acquisition mode by clicking the appropriate button. If you use
Average or Envelope mode, select the number of waveforms for that
mode using the multipurpose knob. If you use Waveform Database mode,
select the number of samples using the multipurpose knob.
Behavior
In Sample mode, the instrument creates a record point by saving one or
more samples during each acquisition interval. Sample mode is the
default acquisition mode. The instrument does no post processing of the
acquired samples in this mode.
In Pk Detect
(Peak Detect) mode, the acquisition alternates between saving the highest sample in
one acquisition interval and the lowest sample in the next acquisition interval. Peak Detect mode
only works with real-time, noninterpolated sampling.
The Hi Res (High Resolution) mode averages all samples taken during an acquisition interval to
create a record point. This average results in a higher-resolution, lower-bandwidth waveform. This
mode only works with real-time, noninterpolated sampling.
