Cursor function Measurements
T2 = Time @ Cursor 2 with respect to the trigger
point
∆T = Time @ Cursor 2 - Time @ Cursor 1
Time is divisions of displacement of the cursor from its
source trigger point multiplied by the source in time/div.
Waveform cursors measure vertical parameters (typically
volts) and horizontal parameters (typically time or
frequency) simultaneously. Each cursor is, in effect, both a
vertical and horizontal cursor. These paired cursors cannot
be moved off of the waveform. The two cursors can have a
different source.
Use screen cursors to indicate an arbitrary X and Y position
in the waveform display area represented by the intersection
of a vertical and horizontal cursor line. Screen cursors
measure both vertical parameters (typically volts) and
horizontal parameters (typically time or frequency).
Histograms
The instrument 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 measurement data for a section of a waveform along one
axis.
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 below. 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.
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.
