Inst IQ Ref Spectrum (DVB-S2/S2X)

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.

When Custom IQ is enabled, Inst IQ Ref Spectrum is the instantaneous spectrum of the IQ Ref Time trace. In other words, Inst IQ Ref Spectrum is the non-averaged versions of IQ Ref Spectrum trace data.
