ARRA AR3221 Variable fine control microwave attenuator

UpUp


For sale is a ARRA AR3221 microwave attenuator. It was a part of a military radar test set. As you turn the shaft with the gear, the shaft egnages something else via some super fine thread, and a shaft moves very slowy in and out of the attenuator box. That's all I know.
