Features & Benefits

Scalability
The Vertex Wireless Channel Emulator is scalable to a broad range of applications. The hardware is capable of supporting as few as two bidirectional RF channels for basic RF testing and as many as 32 unidirectional RF channels to support high channel density applications in one instrument.
Modularity
Separate RF modules are optimized for unidirectional or bi-directional applications and support a variety of different frequency bands; which allows Vertex to be configured for specific test needs using minimal hardware.
Wide frequency range and bandwidth
Vertex has an unmatched frequency range of 30MHz to 5925MHz with a single instrument. Individual bandwidths can be as high as 200MHz per channel and be combined up to 1GHz with concatenation to support frequency hopping.
High channel density in a compact space
Vertex supports up to 36 RF ports and 256 digital links in one 6U rack height. It enables more efficient use of hardware for tests that require higher RF channel counts, such as sophisticated MIMO applications and next-generation 5G services.
Remote programming interface (RPI)
Remote programing is supported through TCP/IP. The RPI commands provide seamless backward compatibly to Spirent’s VR5 HD channel emulator.
Comprehensive 2D/3D channel modeling
The built-in Vertex propagation library offers a vast selection of standard channel models and makes it easy to edit and save changes to create user-defined models, both classical and geometrical.
