High bandwidth general-purpose PXI matrix offers high switching capacity

22-02-2021 | Pickering | Subs & Systems

Pickering Interfaces has released what it claims to be the industry’s highest bandwidth general purpose PXI matrix. Available in 16x8, 2-pole, or high-density 32x8, 2-pole switching configurations, the matrix modules provide bandwidths ranging from 35MHz to 70MHz depending upon path chosen and a VSWR <1.5:1 to 85MHz.


The modules are in two-slot PXI (model 40-588) or PXIe (model 42-588) formats and are built utilising telecommunication grade electromechanical relays capable of hot or cold switching up to 2A at 220VDC/250VAC. Every signal has an accompanying analog ground connection on the front panel connectors for interfacing with cabling accessories. Simple matrix expansion is aided by two groups of front panel Y-axis connections on the 32x8 variant.


Comments Pickering’s Steve Edwards, switching product manager: “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 device high capacity, high bandwidth switching matrix modules are ideal for upgrades to legacy systems or new ATE designs in demanding automotive and defence applications.
