Matrix Attenuators
Digital Matrix Attenuators for Wireless Handover and Signal Fading Tests
Matrix attenuators give engineers precise control over wireless signal paths in lab and production test environments. With configurations supporting dozens of inputs and outputs, they allow for complex multi-channel handover and MIMO testing across 5G, Wi-Fi, and Satcom systems.
Unlike traditional fading simulators or manual attenuators, Vaunix Digital Matrix Attenuators deliver repeatable programmability, affordability, and reliable performance through easy-to-use USB or Ethernet control.

FAQs
What configurations are available for the VMA matrix attenuators?
The VMA series supports configurations from 2x2 up to 64x16, covering a wide range of multi-port test requirements. Models are available for handover testing, MIMO simulation, and multi-DUT automated test systems across sub-6 GHz frequencies.
What test applications are VMA matrix attenuators designed for?
VMA matrix attenuators are used in 5G handover testing, MIMO channel emulation, and multi-path fading simulation. The ability to independently control attenuation across multiple signal paths in a single unit makes them well-suited for complex RF channel modeling in lab environments.
How are VMA matrix attenuators controlled?
VMA matrix attenuators are controlled via the Vaunix Web UI or through the Vaunix API. The API supports Python and other common scripting environments, allowing attenuation values across all ports to be set and swept programmatically without manual intervention.
Do VMA matrix attenuators support fine attenuation step sizes?
Yes. Select VMA models offer step sizes as fine as 0.1 dB, consistent with the resolution available in the single-channel LDA series. Fine step resolution supports accurate fading simulation and precise path loss modeling in multi-DUT test configurations.
