PXI/PXI Express multiplexer for MIL-STD-1553 avionics test and measurement offered by Pickering Interfaces

Aug. 26, 2021
Telecommunications electromechanical relays, the 40/42-739 multiplexer gives a minimal initial signal path resistance of less than 450 milliohms.

CLACTON-ON-SEA, England – Pickering Interfaces in Clacton-On-Sea, England, is introducing the model 40/42-739 PXI/PXI Express multiplexer module optimized for MIL-STD-1553 test and measurement applications.

With a differential bandwidth of 450 MHz -- far exceeding the requirements of MIL-STD-1553 -- the model 40/42-739 is available in single or dual 4:1, 8:1 or 16:1 differential configurations.

Using telecommunications-grade electromechanical relays, the 40/42-739 PXI/PXI Express multiplexer has a minimal initial signal path resistance of less than 450 milliohms.

The module features impedance-controlled differential pairs with a single-ended characteristic impedance of 39 Ohms and a differential impedance of 78 Ohms, within the MIL-STD-1553-specified range of 70 to 85 Ohms.

Its compact, single-slot footprint with PXI or PXI Express control interface provides flexibility in chassis selection and minimizes chassis slot count.

The 40/42-739 PXI/PXI Express multiplexer module is supported by the Pickering Interfaces eBIRST diagnostic tool for ease of maintenance and fault-finding.

The inclusion of a spare relay enables customers with applicable SMT rework training to effect on-site repair, minimizing system downtime. Pickering also offers a range of standard and custom interconnect accessories supporting the 40/42-739 family.
