Inst IQ Ref Spec (Custom IQ)

Menu Path: Trace > Data > Inst IQ Ref Spec

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

The custom IQ demodulator removes carrier frequency error. Therefore, in the error vector spectrum display, you must add the carrier frequency error to marker readouts to obtain exact frequency information. The carrier frequency error (Freq Err) is shown in the symbol table.
