acquisitions, and since the
oscilloscope takes time to
calculate measurement values
and to display data before the
trigger is re-armed, data can be
missed.
In general, Track is the tool to use if you want to capture a continuous
stream of data spaced closely together.
To understand the change in a parameter with time, Trend can be used if
your data is spaced widely apart and longer than the dead-time of the
oscilloscope between acquisitions. Think of Trend as a strip chart recorder
for your oscilloscope.
Creating and Viewing a Histogram
Histograms are graphical representations of data which divides it into
intervals or bins. These intervals/bins are plotted on a bar chart such that
the bar height relates to the number of data points inside each interval/bin.
Various histograms can be setup using Measure or Math dialogs.
Thumbnail versions of Histograms are called Histicons. Also, Persistence
can be applied to Histograms.
PLEASE NOTE THE FOLLOWING:
1. The number of sweeps comprising the histogram is shown on the
trace descriptor label.
2. The range of a histogram is limited to the portion of the trace that is
visible on screen. That is, if you zoom in on a trace, the histogram
does not contain data for that part of the original (no longer visible)
trace.
