FFT Settings panel (Math FFT plot configuration menu) fields and controls.
Field or control Description
FFT Type Magnitude plots the magnitude values of the frequency components.
Phase plots the phase of the signal as a function of frequency.
Window Sets the FFT window type to use for the waveform plot. See FFT windows
on page 322.
Gating
Sets the region of the waveform to analyze for the FFT plot.
None uses the entire waveform record to create the FFT plot.
Screen uses the part of the waveform record displayed on the screen (such
as in Zoom mode) to create the FFT plot.
Cursors uses the waveform data between the cursors to create the FFT
plot.
Vertical Units Sets the vertical scale to Degrees, Radians, or Group Delay.
NOTE. The Vertical Units set when FFT Type = Phase override the Y-Axis
scale setting in the Plot Settings panel.
Only available when FTT Type set to Phase.
Phase Wrap When checked, the phase trace is unwrapped where the trace jumps more
than the number of degrees set in the adjacent field.
Only available when FTT Type set to Phase.
Squelch When checked, the phase trace excludes points that have a voltage smaller
than the specified voltage. The squelch voltage should be set to the
expected noise voltage level. Minimum value is 100 mV, and increments in
units of 100 mV.
When unchecked, the phase trace includes all values.
Only available when FTT Type set to Phase.
Save panel (Math FFT plot configuration menu) fields and controls.
Field or control Description
Save Plot Image Opens the Save As configuration menu to specify the location and name at
which to save an image file of the Plot view.
Save Plot Data Opens the
Save As
configuration menu to specify the location and name at
which to save the Plot view data to a CSV file.
