Measurement of Error Vector Magnitude from Agilent

This video from Agilent Technologies shows error vector magnitude measurement taken from the lab 3 of the DreamCatcher ME 1100 university courseware. The IQ signal is first demodulated using VSA Software and the measure of the modulated RF signal using oscilloscope and YSA Software.

Error vector magnitude (EVM) measurements can provide a great deal of insight into the performance of digitally modulated signals. With proper use, EVM and related measurements can pinpoint exactly the type of degradations present in a signal and can even help identify their sources.
