This paper presents a measurement system and
experimental examples of error vector magnitude measurements
on a wireless local area network receiver under several radio
frequency impairments, with emphasis to local oscillator phase
noise. An algorithm that cancels the phase and frequency carrier
synchronization error is presented. Typical base band figure of
merit are obtained under influence of these impairments. The
described method allows the experimental calculation of error
vector magnitude without a dedicated vector analyzer.
