Using the Oscilloscope

82

To make a measurement on a waveform

• Click and hold the mouse button or touch screen stylus on a measurement

icon, then drag the icon to the waveform event you want to measure then
release.
or

• Click a measurement icon, then specify which source you want to measure in

the dialog box that is displayed.
For measurements on waveform features, such as those that involve waveform
edges, if you click the measurement icon and specify a source, the
measurement defaults to using the feature closest to the horizontal reference
point. When you make the measurement using drag-and-drop, the
measurement uses the waveform feature closest to the point where you drop
the icon.

Only the most commonly used measurements are available on the toolbar.
Others are available by selecting them from the Measure menu. A few
specialized measurements are available only through the remote programming
command set. See the

Programmer’s Reference

.

When you drag and drop a measurement icon on a waveform, notice that the
icon outline changes color to match the color of each waveform it touches.
This lets you easily see which waveform will be measured when you release.
Also, the measurement results are also displayed in color to make it easy to
see which waveform source is being measured.

For edge-sensitive measurements, when you drop the measurement icon on a
waveform, a geometric icon appears in the waveform marker color. This icon
shows exactly where the measurement is being made. The icon is also
displayed next to the measurement results readout to associate the readout
with the waveform and feature being measured. See figure 3-25. This feature
helps you distinguish measurement results from each other when you make
multiple measurements on the same waveform, but at different waveform
features. For example, a series of rise time measurements on several different
edges of the same waveform all have unique geometric icons to show each
measurement’s location.
