Figure 81 FFT Waveform
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
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.
Note:
Signals with DC components or deviation would cause error or deviation of
the FFT waveform components. To reduce the DC components, set the
Channel Coupling to AC.
To reduce the random noise and aliasing frequency components of repetitive
or single pulse, set the Acquisition of the oscilloscope to Average.
Note: please refer to the cursors chapter to obtain the method of using cursors.
