The Vaunix Digital Attenuator Matrix Systems are easily customized, bidirectional, non-blocking test instruments. Attenuation matrixes are ideal instruments for mobile operators, Wi-Fi chip manufacturers and radio development teams testing handover and MIMO performance in research labs, product verification and development environments. The matrix attenuator allows the user to direct multiple input signals to multiple outputs while controlling the signal power on all paths.

The VMA-6x4-8110 Attenuator Matrix System is a rack mounted 6 input x 4 output non-blocking test instrument. The VMA-6x4-8110 provides 110 dB of attenuation control range from 700 to 7250 MHz with a step size of 0.1 dB on all 24 possible path combinations. The attenuators are easily programmable for fixed attenuation, swept attenuation ramps and fading profiles using our highly developed Windows API DLL files and Linux platforms.

The VMA-6x4-8110 is USB powered, and controlled through a single USB or Ethernet port on the rear of the chassis. All output signals are available on the front panel with SMA connectors.
