The 40-739-002 (PXI) and 42-739-002 (PXIe) are dual 16-channel 2-pole multiplexers designed specifically for physical layer multiplexing or demultiplexing differential signals that conform to the MIL-STD-1553 specification. The module can be supplied as a single or dual 16-channel 2-pole multiplexer with each signal pair having a controlled 78 Ohm differential impedance.

The module is ideal for the testing of multiple devices that use a serial communication interface, allowing the test system to select one target device from many. The design is bi-directional to permit use as a multiplexer or de-multiplexer with no impact on performance. The module uses long lifetime electromechanical relays characterized for use in communications systems.

Supported by eBIRST

eBIRST switching system test tools simplify switching system fault-finding by quickly testing the system and graphically identifying the faulty relay.
