A histogram source can be any waveform (channel or math), including a
reference waveform.
In addition to using limit controls to set histogram box boundaries, you can also
use standard Windows drag-and-drop to resize and reposition the histogram box.
Histograms are not available in FastFrame, Record View XY, or Zoom modes.
Histogram Size. The maximum vertical histogram size is 200. The maximum
horizontal size is 500.
Histogram Counting Stays On. Turning on histograms starts histogram counting
and data accumulation. A sample histogram display is shown in Figure 3--39.
Histogram data is continuously accumulated until you explicitly turn off
histograms. This allows you to continue collecting histogram data even when
you turn off the histogram display.
Use the procedure that follows to quickly take a measurement based on the
default settings for histograms.
