This unit
The Astronics / EADS / Racal 1260-45A is a C-size VXIbus high-density switch matrix module engineered for complex signal routing in automated test systems. This single-slot unit delivers eleven factory-configurable matrix arrangements - from four 4x16 matrices to a single 16x16 matrix - enabling flexible signal path management within a single chassis. The module switches signals up to 1 A and 250 VDC, with bandwidth performance ranging from 25 MHz (4x16, 4x32 configurations) to 20 MHz (4x64 configuration). Guard relays at row inputs provide non-latching behavior with automatic disconnect on power loss, protecting the Unit Under Test. Jumper-selectable bypass enables full latching relay operation for communication applications requiring maintained signal paths.
Technical Specifications
