In Signal Analyzer (SA) mode, the E6651A Test Set may be
used to analyze Mobile WiMAX uplink signals using
modulation, spectrum and flatness analysis. Modulation
Analysis mode displays the OFDM signal in both frequency
and time domain form. The Spectrum Analysis functionality,
implemented using a Fast Fourier Transform (FFT)
algorithm, displays the measured WiMAX signal in frequency
domain graph form. This mode is used to analyze the center
frequency, bandwidth and amplitude of the broadband signal.
Flatness analysis allows for the comparison of power
intensity among spectral components.
