95% EVM (Digital Demod)

95% EVM exists only for the EDGE Enhanced Data for Global Evolution: A technology that gives GSMA and TDMA similar capacity to handle services for the third generation of mobile telephony. EDGE was developed to enable the transmission of large amounts of data at a high speed, 384 kilobits per second. (It increases available time slots and data rates over existing wireless networks.) demodulation format. 95% EVM is the error-vector-magnitude (EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format.) below which 95% of the individual symbol EVMs occur.

For example: At 200 averages, with each measurement containing 142 symbols, there would be symbol EVMs for a total of 200 ´ 142 symbols. The 95% EVM is the EVM for which 200 ´ 142 ´ 0.95 symbols have lower EVMs, or 200 ´ 142 ´ 0.05 have higher EVMs.
