Spirent SR5500 Wireless Channel Emulator

The SR5500 Wireless Channel Emulator is the most complete and efficient solution available for accurately testing SISO and 2x2 MIMO wireless receivers. The system can be configured to manage intricate MIMO-OTA testing (via simplified graphical controls) and to perform Virtual Drive Testing (VDT) to reduce the cost and time burdens associated with drive testing.

The SR5500 helps isolate performance issues early in the development and design verification cycle, accelerating time to market and minimizing post-deployment issues.
