PXI/PXIe Multiplexer Module Supports MIL-STD-1553 Testing

Aug. 3, 2021
Pickering Interfaces MIL-STD-1553 testing Model 40/42-739 has a differential bandwidth of 450 MHz, and is available in single or dual 4:1, 8:1 or 16:1 differential configurations.

Pickering Interfaces recently launched a PXI/PXIe multiplexer module optimized for MIL-STD-1553 testing applications. With a differential bandwidth of 450 MHz, the model 40/42-739 is available in single or dual 4:1, 8:1 or 16:1 differential configurations. Features include telecommunications-grade electromechanical relays, an initial signal path resistance of less than 450 mΩ, and impedance-controlled differential pairs with a single-ended characteristic impedance of 39 Ω and a differential impedance of 78 Ω.

According to Pickering’s Switching Product Manager, Steve Edwards, “originally introduced in the 1970s, MIL-STD-1553 was intended for use in military aircraft. However, now it is used as the basis for ground-based military vehicles, weapons systems, commercial aircraft and space applications. The 40/42-739 should have many applications in aerospace and military ATE systems, and—being designed with a 78 Ω differential impedance—the 40/42-739 can potentially support applications for 75 Ω switching such as for video signals.”

The 40/42-739 PXI/PXIe multiplexer module is supported by the Pickering Interfaces’ eBIRST diagnostic tool. 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.
