  • The SR5500 emulates wideband radio channel characteristics such as time-varying multi-path delay spread, fast fading, shadow fading and channel loss for advanced receiver implementations using diversity, beamforming and MIMO
  • Optional configurations let you stick to your budget without risk. Systems are always fully upgradeable to our most powerful modular configuration
  • Spirent’s exclusive Fading Lab lets you create a repeatable RF environment from data sets, whether captured on channel-sounding equipment or generated in software
  • An advanced fading engine ensures accurate testing of sophisticated technologies like E-UTRA (LTE), HSPA, HSPA+, EV-DO, WLAN and WiMAX
  • Spirent’s exclusive DEE gives you the flexibility to quickly and easily turn simple spreadsheets into complex RF scenarios ready to use for testing
