Error Vector Spectrum (DVB-S2/S2X)

Menu Path: Trace > Data > Demod > CCn > Error Vector Spectrum

Trace > Data > Demod > Display CC > Error Vector Spectrum

There are two types of traces in the Trace > Data > Demod menu that display component carrier data: CCn (component carrier is fixed), and Display CC (component carrier is dynamically selected using the Carrier Aggregation > Selected CC for Trace Display parameter). See About Demod Per-Carrier Trace Types for more information.

The Error Vector Spectrum trace shows the spectrum of the Error Vector Time trace. In other words, the VSA derives the Error Vector Time trace and then windows and FFTs this trace to produce the Error Vector Spectrum trace.

The center frequency and span for the Error Vector Spectrum trace is identical to the IQ Meas Spectrum.
