Measure the FFT waveform
Press the Cursors button on the front panel to turn on the cursor function, and then
specifying the source as "Math". X1 and X2 cursors can be used to measure the
frequency value at the cursor position.
Only the maximum parameter of the FFT is supported in automatic measurement.
Note: DC components in the signal may show a large amplitude near 0 Hz. If your
application does not require measurement of the DC component, it is recommended
to set the coupling mode of the source channel to "AC".
