The Astronics 1260-100 is a VXIbus switch carrier designed for high-density switching in automated test equipment systems. This two-slot, C-size VXIbus module accommodates up to six Adapt-a-Switch™ plug-in cards and supports control of up to twelve cards via the integrated Option 01T interface. The carrier features an analog bus for dynamic software-controlled configuration of multiplexers and matrices, with EMI/RFI shielding between plug-in slots to maintain signal integrity and minimize crosstalk.
