Astronics / EADS / Racal 1250-30 Scanner/MUX Board

The Astronics / EADS / Racal 1250-30 is a Scanner/Multiplexer board designed for signal routing and data concentration within the Racal 1250 Series Universal Switch Controller system. This modular plug-in card enables automated test environments to manage signal distribution across DC to 26.5 GHz applications, handling low-level, power, RF, and microwave signals through integration with compatible switch modules. The board features a 10-wire analog bus and DB25 connectors for output drivers, sense inputs, and supply voltage management, with control via message-based interface on compatible chassis.
