Measurement setups Select a time measurement
Behavior
From this control window, you can do the following:
Define time mea surements for the selected waveforms.
Select a waveform source using the Channels Selector (see page 258). You can measure live
waveforms, math waveforms, or reference waveforms.
Create a list of measurements to appear in the main graticule or in a separate measurement window.
Define the u nique reference l
evels for each measurement.
Use gating to limit the measurements to a specific area of the waveform.
Set up m easurement statistics.
Set up histograms to evaluate specific regions of the waveform.
NOTE. Automatic measurements are not available on digital channels.
TIP. Turn on Fast Acquisitions to enhance your measurements. In Fast Acquisitions mode, measurements
are calculated on an array of acquired waveforms. As the waveforms accumulate (with persistence on),
your measurement accuracy may increase. However, only one or two channels can be displayed when you
take automatic measurements using Fast Acquisitions mode.
If three or more channels are displayed, Fast Acquisitions mode is turned off, and then the requested
measurements are made. Fast Acquisitions mode is not automatically turned back on when you select
fewer than three channels.
What do you want to do next?
Go to a step-by-step procedure to set up the instrument for taking measurements. (see page 604)
Select a time measurement
Type From the Measure menu, select Measurement Setup; then open the Time tab.
To use
Use the Time tab to select automatic time measurements.
1. Select a source with the Channels
Selector
(see page 258).
2. Click a Measurements button to add a Time measurement to the Measure list:
274 DSA/DPO70000D, MSO/DPO/DSA70000C, DPO7000C, and MSO/DPO5000 Series
