PXI Matrix Modules with up to 6,144 Crosspoints

17 September 2019 - Pickering Interfaces launched a new 0.5Amp ultra-high-density PXI matrix module family that delivers up to 6,144 crosspoints. With a switching density 39% higher than competing devices, the 40-558 allows a complete functional ATE system to be housed in a single 3U PXI chassis, and the integrated BRIC design saves on valuable chassis slots compared to standard PXI matrix modules.

Part of Pickering Interfaces’ BRIC large PXI Matrices range, the new 40-558 modules are available in two, four or eight-slot widths for matrix sizes between 64x16 and 1,008x6. The modules are fitted with high quality, ruthenium-sputtered reed relays – manufactured by sister company, Pickering Electronics – which feature a very long life with good low-level switching performance and excellent contact resistance stability. Automatic isolation relay switching maximizes bandwidth and reliability. Spare relays are included with the module to facilitate easy maintenance with minimum downtime.

The BRIC’s internal high performance screened analog backplane minimizes the complexity and cost of cable assemblies; Pickering has a range of standard cables available for the 40-558 and can construct custom cables for all its PXI modules. A choice of 6, 8, 12 and 16 pole analog bus widths and dual analog bus options are available.

“This is industry’s highest density reed relay PXI solution,” said Keith Moore, CEO at Pickering Interfaces. “By only using the highest quality Pickering instrument-grade reed relays, we are able to guarantee our matrices for three years. Engineers can be sure they are choosing a high reliability product to match their high reliability applications.”

The 40-558 BRIC PXI matrix modules can be operated in Fast Mode via the VISA driver with multiple relay operation in one command or provide the convenience and simplicity of IVI drivers. Pickering’s signal routing software, Switch Path Manager, allows easy programming of the BRIC matrix modules. Extensive accessory support is available, including Pickering’s Built-in Relay Self-Test (BIRST) and eBIRST Switching System Test tools which provide a quick and simple way of finding relay failures within the modules.

The 40-558 PXI matrix modules suit many industries; however, typical applications include automotive and aerospace ECU and semiconductor package testing. Dual analog bussing for the narrower matrix options enables completely separate matrices within a single module for parallel testing.
