Viewing Thumbnail Histograms
Histicons are miniature histograms of parameter measurements that appear below the grid. These thumbnail
histograms let you see at a glance the statistical distribution of each parameter.
In the menu bar, touch
Measure
, then one of the Measure Mode buttons:
Std Vertical
,
Std Horizontal
, or
My
Measure
.
Touch the
Histicons
checkbox to display thumbnail histograms below the selected parameters.
Note:
For measurements set up in My Measure, you can quickly display an enlarged histogram of a thumbnail
histogram by touching the Histicon you want to enlarge. The enlarged histogram will appear superimposed on
the trace it describes. This does not apply to "Std Vertical" or "Std Horizontal" measurements.
Persistence Histogram
You can create a histogram of a persistence display also by cutting a horizontal or vertical slice through the
waveform. You also decide the width of the slice and its horizontal or vertical placement on the waveform.
This math operation is different than the "Histogram" math operation and is not affected by
Center
and
Width
settings made there.
