9. Optionally, define a gate area to restrict the measurement to an extract of the wave-
form, as described in chapter 5.2.2.7, "Using Gate Areas", on page 150.
If you enabled the measurement with the toolbar icon and drew a rectangle on the
diagram, the gate area is automatically defined and enabled.

5.2.2.4 Creating a Histogram
Histograms can be used to evaluate the sample value occurances directly. They are a
prerequisite for histogram measurements.
See also: chapter 5.2.1.4, "Histograms", on page 138.
To create a histogram quickly with toolbar icons
1. Select the waveform for which you need a histogram.
2. Tap the either the "Vertical histogram" or the "Horizontal histogram" icon on the tool-
bar.
Note: The "Horizontal histogram" icon has to be activated in the toolbar configuration:
"Display" menu > "Toolbar"
3. Tap the diagram with the waveform to be measured, or draw a rectangle on the screen
to define the area on which the histogram is to be based.
The histogram range is indicated in the diagram and a histogram with the selected
waveform as a source is defined and displayed.
To create and configure a histogram in the dialog box
1. Select "Meas > Histogram", or touch and hold an existing histogram or histogram
area.
The "Histogram Setup" dialog box is displayed.
2. If no histogram was defined yet, tap the "Add" icon in the upper right corner of the
dialog box to create a new tab for histogram configuration.
To copy an existing histogram and configure a new one based on those settings, tap
the "Copy" icon.
