Measuring Waveforms
3- 130
TDS5000 Series User Manual
Using Histograms (Optional)
The oscilloscope can display histograms constructed from the selected waveform
data. You can display both vertical (voltage) and horizontal (time) histograms,
but only one at a time. Use histogram measurements to get statistical measure-
ment data for a section of a waveform along one axis.
NOTE. Histograms are available only when you purchase the Advanced Analysis
option. To upgrade your oscilloscope, purchase TDS5UP Option 2A.
The histogram source can be any channel, math, or reference waveform.
Turning on histograms starts histogram counting and data accumulation. A
sample histogram display is shown in Figure 3--36. Histogram data is continu-
ously accumulated until you explicitly turn off histograms. This allows you to
continue collecting histogram data even when you turn off the histogram display.
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 or Zoom modes.
