Spectrum (cdma2000/1xEV-DV)

Menu Path: Trace > Data > Channel 1 > Spectrum

Spectrum trace is the frequency spectrum of the pre-demodulated Time trace data. The Time data is Windowed and FFTed to create the Spectrum display.

If averaging is on, Spectrum trace data is the averaged Instantaneous Spectrum trace data. When averaging is set to zero, the Spectrum trace data is equal to the Inst Spectrum trace data.
