New 0.5A large PXI matrix modules have up to 6144 crosspointsPickering Interfaces is launching a 0.5A ultra-high-density PXI matrix module family that delivers up to 6144 crosspoints. With a switching density 39 per cent 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 64×16 and 1,008×6. 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 maximises bandwidth and reliability. Spare relays are included with the module to facilitate easy maintenance with minimum downtime.

The BRIC’s internal high-performance screened analogue backplane minimises 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 analogue bus widths and dual analogue bus options are available.

Keith Moore, CEO at Pickering Interfaces says: “This is industry’s highest density reed relay PXI solution. 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.

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 and Pickering’s signal routing software, Switch Path Manager, allows easy programming of the BRIC matrix modules.

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