Display a Spectrum plot
Use this procedure to display a spectrum plot.
To display a time spectrum plot you must be taking a measurement.
1. Double-tap a measurement badge.
The Measurement configuration menu is displayed.
2. Tap the Spectrum plot button.
The Spectrum plot is displayed in a separate Plot view.
3. Double-tap in the plot view to open a configuration menu for that plot.
Display an XY or XYZ plot
Use this procedure to display an XY or XYZ plot.
1. Tap Add New... Plot.
The Plot configuration menu is displayed.
2. If creating an XY plot, tap XY.
3. If creating an XYZ plot, tap XYZ.
4. Tap the X Source drop down and select the X Source from the list.
5. Tap the Y Source drop down and select the Y Source from the list.
6. If creating an XYZ plot, tap the Z Source drop down and select the Z Source from the list.
7. Tap Add.
The plot is displayed in a separate Plot view.
8. Double-tap in the Plot view to open a configuration menu for that plot.
Display an FFT math waveform
Use this procedure to display an FFT math waveform.
The FFT process mathematically converts the standard time-domain signal (repetitive or single-shot acquisition) into its
frequency components. The FFT function processes the waveform record and displays the FFT frequency domain record, which
contains the input signal frequency components from DC (0 Hz) to ½ the sample rate (also called the Nyquist frequency).
1. Tap Add New Math to create a math waveform and open the Math configuration menu.
2. Tap Source and select the signal source from the list.
3. Set Math Type to FFT.
The FFT of the waveform is displayed in an FFT Math waveform view.
4. Double-tap on the FFT waveform display to open a configuration menu to further refine the FFT display. See Math FFT plot
configuration menu (Math waveform) on page 320.
