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-Q64X16SE Attenuator Matrix System is a rack mounted 64 input x 16 output nonblocking test instrument. The VMA-Q64X16SE provides 90 dB of attenuation control range from 500 to 6000 MHz with a step size of 0.1 dB on all 512 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-Q64X16SE is AC powered and controlled through a single Ethernet port on the rear of the chassis. All input and output signals are available on the front panel with SMA or optional N Type connectors.
