After having properly set up the acquisition, triggering, and display of your waveform, you can then analyze the results.
Select from features such as displaying automatic measurements, using cursors to measure specific parts of a waveform,
using math to perform an operation on two waveforms, and using F FT to display the frequency components of a signal. You
canalsouseGating to analyze only a specified part of a waveform when you take measurements. (See page 55, Ta ki ng a
measurement on just a part of the waveform (Gating).)
Taking automatic measurements
Automatic measurements are a way to quickly take common measurements on a waveform, such as signal frequency,
period, ris
e and fall times, and so on. You can take up to a total of six measurements at once, on any combination of input
channels and a m ath waveform. The measurements are shown o n the main screen in the order they were selected.
To take an automatic measurement:
1. Acquire and display a triggered waveform.
2. Push Meas
ure.
3. Push the s
ide-menu button to select the
channel on which to take measurements.
4. Use the M ultipurpose knob to select and click a measurement. (See page 52, Automatic measurement descriptions.)
The Measurement Selection bar at the top of the screen updates to show that a measurement was selected for that
channel (indicated by color), up to a maxim um of six measurements total to display.
5. Measurements with a down triangle contain a list of the input channels to use for that measurement when selected. Select
and click the input channels. Then push the Menu On/Off button to close the list.
6. To unselect a measurement, highlight that measurement and click the Multipurpose knob. To deselect a measurement for
a different channel than the current channel, push the side-menu button for the channel of the measurement, then use the
knob to select and click the measurement to remove it.
7. To unselect all measurements, push the Remove All Measurements side-menu button.
8. To close the measurement menu and show
the selected m easurements on the screen,
push the Menu On/Off button.
Measurements are shown on the screen.
Pushing the Menu On/Off button also turns
