Full screen NEXUS-3

3 GHz Bi-Directional RF Attenuator Matrix Switch

General Description:

The NEXUS-3 is a bi-directional fully non-blocking matrix switching system that can accommodate 32x32 ports in a compact 6 RU chassis. The matrix supports MIMO connections, e.g. any of the 32 ports of A or B can be routed to any or all of the 32 ports of B or A. It provides continuous operation over the frequency range of 700 to 2800 MHz and is ideal for testing wireless communication technologies for 4G (LTE, HSPA+) and beyond. Built-in programmable attenuators provide ease-of-use testing  of  signal fade and emulation of mobility and handoff testing scenarios. Test system configurations can be remotely reconfigured and consistently reproduced in minutes, eliminating the need for time consuming manual patch panel changes that can lead to RF signal loss and unpredictable results. Utilization of the NEXUS-3 will improve test cycle rotation times and speed new products time to market.
