Analyzing Waveforms
4. To remove all measurements, click Clear
All .
5. To remove multiple measurements, click
and drag to select the measurements,
and then click
Clear Selected .
You can also choose a measurement
for the selected waveform directly in
the Measure menu. (See page 115,
Automated Measurement Selections
.)
Quick Tips
Automatic measurements are not available for digital channel waveforms. On MSO70000/C instruments you can take a
measurement of a digital channel waveform by first send the digital channel to an analog channel using iCapture. (See
page 57,
Viewing Analog Characteristics of Digital Waveforms .)
In roll mode, measurements are not available until after you stop the acquisition.
WARNING. If there is vertical clipping, there may be a dangerous voltage on the probe tip, but the readout will indicate a low
voltage. A symbol appears in the measurement readout if a vertical clipping condition exists. Automatic amplitude-related
measurements where the signal is vertically clipped produce inaccurate results. Clipping also causes inaccurate amplitude
values in waveforms that are stored or exported for use in other programs. If a math waveform is clipped, it will not affect
amplitude measurements on that math waveform.
