Available in 16×8, two-pole, or high-density 32×8, two-pole switching configurations, PXI matrix modules offer bandwidths ranging from 35 MHz to 70 MHz depending upon path selected and a VSWR less than 1.5:1 to 85 MHz.
The modules are in two-slot PXI (model 40-588) or PXIe (model 42-588) formats and are constructed 
using telecommunication-grade electromechanical relays capable of hot or cold switching up to 2 A at 220 Vdc/250 Vac. Every signal has an accompanying analog ground connection on the front panel connectors for interfacing with cabling accessories. Simple matrix expansion is facilitated by two groups of front panel Y-axis connections on the 32×8 variant.
Comments Pickering’s Switching Product Manager, Steve Edwards: “The 40/42-588 modules’ increased bandwidth provides compatibility with higher frequency test signals. With careful matrix design and isolation switching, a high switching capacity can still be offered while maintaining excellent RF performance. These modules also offer electrically compatible replacement of another vendor’s legacy VXI switching product. This compatibility is part of Pickering’s VXI to PXI replacement program.”
The new 40/42-588 high capacity, high bandwidth switching matrix modules are suitable for upgrades to legacy systems or new automated test equipment (ATE) designs in demanding automotive and defense applications. The modules are supported by Pickering’s eBIRST diagnostic test tools. Like all Pickering’s products, the 40/42-588 modules carry a three-year warranty, and come with spare relays that allows customers—with appropriate training—to do repairs on-site, minimizing system downtime. A range of interconnect accessories are also available to support the 40/42-588 family.
