To measure FFT waveform:
To make cursor measurements, press the Cursors button, and then press the Mode
softkey to select On to turn the cursors, Use the X1 and X2 cursors to measure the
frequency values and the difference between two frequency values (ΔX). Use the Y1 and
Y2 cursors to measure amplitude in dB and difference in amplitude (ΔY).
You can find the frequency value at the first occurrence of the waveform maximum by
using the X at Max Y measurement.
