To View 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.

1. In the menu bar, touch Measure, then one of the Measure Mode buttons: Std Vertical, Std

Horizontal, or My Measure.

2. 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.

To Set Up Persistence Histograms

1. In the menu bar, touch Math, then Math Setup.
2. Touch one of function tabs F1 through Fx. (The number of math traces available depends

on the software options loaded on your scope. See specifications.)

3. Touch

inside

the

Source1 field and select a source from the pop-up menu.

4. Touch

inside

the

Operator1 field and select Phistogram

from the Select Math

Operator menu.

5. Touch the "Phistogram" tab, then touch inside the Slice Direction field and select

Horizontal or Vertical slice from the pop-up menu.

6. Touch

inside

the

Slice Center field and enter a value, using the pop-up keypad.

7. Touch

inside

the

Slice Width field and enter a value, using the pop-up keypad.

Note: You can use the front panel Adjust knobs to move the Slice Center line and the Slice Width boundary lines.
