Quintech NEXUS-4 32×32 Bidirectional 6 GHz RF Attenuator Matrix Switch

Quintech NEXUS-4 32×32 Bidirectional 6 GHz RF Attenuator Matrix Switch 

The Quintech NEXUS-4 is a fully non-blocking, bidirectional 32×32 RF attenuator matrix switch for automated wireless testing across 400 MHz–6 GHz. Its modular architecture can expand to 64×64 ports, supporting large-scale test environments with multiple MIMO base stations, devices and shared laboratory instruments.

Any Port A connection can be routed bidirectionally to any Port B connection while supporting RF signal splitting and combining. Solid-state switching provides fast, repeatable and glitchless reconfiguration, eliminating manual patch-panel and cabling changes between test scenarios.

A programmable attenuator at every crosspoint provides 0–60 dB of adjustment in 0.5 dB steps, enabling free-space path-loss simulation, signal-fade testing and mobility emulation. Local operation is available through the front-panel LCD, while Ethernet, Telnet, SNMP, TCP/IP, an embedded web server and an API support automated remote control.

Optional Q-LAAMP management software coordinates equipment resources and test schedules to improve laboratory utilization and reduce setup time.
