The Keysight Propsim FS8 is a compact RF channel emulator for advanced wireless communication system testing. It simulates complex, real-world radio channel conditions to evaluate device and network performance under realistic scenarios, from R&D through conformance testing. The FS8 delivers full-stack, end-to-end protocol signaling and RF performance testing using coherent 3D propagation channels. Its scalable architecture supports 2 to 8 RF channels, multiple MIMO configurations, MANET topologies, and LTE carrier aggregation up to 4CC bands. The compact 6U form factor integrates readily into rack or benchtop environments, with multi-unit setups available for expanded capabilities.
