  1. Competitive Summary • EVM is used to measure overall signal quality • Lab equipment must not be a contributing factor in degrading the users signal, especially for higher modulation schemes • Superior Channel fidelity is required in test equipment when testing higher order modulation schemes such as HSDPA, EVDV, and WLAN 64 QAM

  2. Competitive Summary • WCDMA/HSDPA – 16QAM signal • A 16 QAM signal was fed thru both products resulting • SR5500 EVM = 1.4967 %rms • Competitor EVM = 5.9286 %rms SR5500 Competitor

  3. Competitive Summary • WLAN – 64QAM signal • A 64 QAM signal was fed thru both products resulting • Baseline EVM = -30.595 dB • SR5500 EVM = -29.106 dB • Competitor EVM = -20.895 dB • Note: WLAN requires -25 dB minimum EVM

  4. Competitive Summary SR5500 Baseline Competitor
