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-Q8X8SE Attenuator Matrix System is a rack mounted 8 input x 8 output non-blocking test instrument with an optional integrated Windows PC for independent operation. The VMAQ8X8 provides 90 dB of attenuation control range from 500 to 6000 MHz with a step size of 0.1 dB on all 64 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-Q8X8SE is AC powered and controlled through either the USB/Ethernet interface or by accessing the internal Windows PC from the rear of the chassis. RF input signals enter through the rear panel with output signals available on the front panel.
