Error Vector Spec (Digital Demod)
When Error Vector Time trace. In other words, the VSA derives the trace and then windows and FFTs this trace to produce the trace.
is enabled, the trace shows the spectrum of theThe 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 (symbol table.
) is shown in theThe center frequency and span for the IQ Meas Spec.
trace is identical to the
