Spectrum (MB-OFDM)

Menu Path: Trace > Data > Channel 1 > Spectrum

The Spectrum trace shows the frequency spectrum of the Time trace. If averaging is off (MeasSetup > Average > Average Type > Off), the Spectrum and Instantaneous Spectrum displays are identical.

The Spectrum trace is derived from pre-demodulated time data, which is 20% larger than the Result Length, when Measurement Interval = Result Length. Otherwise, this trace displays only the Measurement Interval.

If averaging is On (MeasSetup > Average > Average Type > On), a scan is not included in the average if any of these conditions exist: Pulse Not Found, Sync Not Found, Carrier Unlock, or certain DATA?

Compare this spectrum with the Spectral Mask.
