VAUNIX VMNA-7250-8 Mesh Network Attenuator – available from bq-microwave
With the VAUNIX VMNA-7250-8, bq-microwave expands its Lab Brick portfolio with a powerful 8-port mesh network attenuator system. This rack-mounted crossbar test instrument covers the 700 to 7250 MHz range and provides a programmable attenuation range of 110 dB with 0.1 dB step size on all 28 possible path combinations.
What sets the VMNA-7250-8 apart
A mesh network attenuator enables controlled, bidirectional attenuation of signal levels between multiple ports – ideal for realistically reproducing radio network topologies in the lab. The VMNA-7250-8 is a nonblocking 8-port crossbar system: each of the 28 signal paths can be set independently. The attenuators are programmable for fixed attenuation, swept attenuation ramps and programmable fading profiles.
