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-Q24x8SE Attenuator Matrix System is a rack mounted 24 input x 8 output nonblocking test instrument with an integrated Windows server for independent operation. The VMA-Q24x8SE provides 90 dB of attenuation control range from 500 to 6000 MHz with a step size of 0.1 dB on all 192 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-Q24x8SE is AC powered and controlled through a single Ethernet port on the rear of the chassis. RF input signals enter through the rear panel with output signals available on the front panel.
