Inst Err Vect Spec (Digital Demod)

When Digital Demod is enabled, the Inst Err Vector Spec trace shows the instantaneous spectrum of the Error Vector Time trace. This is the non-averaged Error Vector Spec trace data.

The digital 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.

The center frequency and span for Inst Err Vect Spec is identical to the IQ Meas Spec.
