2 Using the Oscilloscope
For measurements on waveform features, such as those that involve waveform
edges, if you click a 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.
The most commonly used measurements are available in the drag and drop area.
Others are available from the Add Measurement dialog box.
When you drag and drop a measurement icon on a waveform, the icon outline
changes color to match the color of each waveform it touches so you can easily
see which waveform will be measured when you release.
For edge-sensitive measurements, when you drop the measurement icon on a
waveform, a circled number appears in the waveform marker color. This number
shows exactly where the measurement is being made. It is displayed next to the
measurement readout in the Results area.
This feature helps you distinguish measurement results from each other when you
make multiple measurements on the same waveform, but at different waveform
features.
Using quick measurements
• You can define the [Multi Purpose] key to perform one of these quick actions:
• QuickMeas—performs automatic measurements
• QuickPrint—prints the screen image to the default printer
• QuickScreen—saves the screen image to a file
• QuickSetup—loads a setup file
• QuickWaveform—saves waveform data to a file
• QuickSave—saves a customized set of screen images or waveforms to a file
• QuickEmail—sends an email of the current screen image
• QuickExecute—runs an executable file
• QuickControl—cycles through the possible front panel control sources
• QuickComposite—saves composite data to a file
The action taken when the [Multi Purpose] key is pressed (or Utilities > Multipurpose
is chosen) depends on the feature selected in the Customize Multipurpose dialog
box (Utilities > Customize Multipurpose...). The default feature is QuickMeas.
• To turn on the quick measurement display, press the [Multi Purpose] key.
The 10 preset measurements defined in the Quick Measurement configuration
are enabled and results appear on the screen for the first waveform source.
• To measure parameters for another waveform, press the [Multi Purpose] key until
that waveform is the one shown in the measurement readout. Continuing to
press the [Multi Purpose] key cycles through each of the waveforms available.
