- Pickering Interfaces, a provider of modular switching and signal simulation solutions for electronic test and verification, announces the 40/42-739 series PXI/PXIe multiplexer module that has been optimized for MIL-STD-1553 test applications.
Featuring a 450 MHz differential bandwidth, which Pickering believes exceeds the requirements of MIL-STD-1553, the 40/42-739 Series PXI module is available in 4:1, 8:1 or 16:1 single or dual differential configurations.
Incorporating quality telecom electromechanical relays, this multiplexer, which occupies only one slot in the PXI chassis, has a minimum track resistance of less than 450 mΩ. The module features impedance-controlled differential pairs with a single-ended characteristic impedance of 39 Ω and a differential impedance of 78 Ω, in the 70-85 Ω range specified by MIL-STD-1553.
“Introduced in the 1970s, the MIL-STD-1553 standard was originally intended for the military aircrafts. However, it is now used for military ground-based vehicles, weapons systems, commercial aircrafts and space applications. The 40/42-739 module should therefore be suitable for a variety of automated test systems in the aerospace and defense industries. Featuring a 78 Ω differential impedance, it can potentially support 75 Ω switching applications such as for video signals,” says Steve Edwards, Pickering’s switching product manager.
The 40/42-739 Series PXI/PXIe Multiplexer Module is supported by Pickering Interfaces’ eBIRST diagnostic tool for easy maintenance and troubleshooting. A spare relay is provided to allow customers with SMT troubleshooting training to perform field repairs. This minimizes test system downtime.
