Measurement filter = root raised cosine, reference filter = raised cosine, analysis Length = 400 symbols, 20 averages

14

SEM is specified with noise reduction and at least 30 averages for 802.11a/n/ac signals in 5 GHz band. Residual noise performance of the MDO4000B may exceed SEM mask at frequency above 5.85 GHz
