The product family consists of three ranges that provide various switching topologies. The PXI module, model 40-121, provides SPST (13 or 26) or 2:1 (8 or 16) multiplexer configurations. The PXI/PXIe modules, models 40-590 and 42-590, offer matrix functionality (8x4 or 16x4), while the LXI, model 65-290, is based on Pickering's established 2U LXI modular chassis (model 65-200) and accepts up to six 8x16 or 16x16 matrix plug-ins. Individual plug-ins are loaded from the front of the chassis, which is advantageous for expansion and maintenance.
To enable future scalability of the test system, the PXI/PXIe Model 40/42-590 and LXI Model 65-290 products include loop-thru functionality, allowing array size expansion by interconnecting adjacent modules in a chassis using short standard cables. The former allows expansion along the X-axis, while the latter allows expansion along both the X and Y axes, facilitating flexible array sizes up to 16x96 per chassis with easy expansion to additional chassis. Each PXI module occupies only one chassis slot. This footprint is achieved using high-density coaxial connectors to support low leakage measurements. The PXI Model 40-121 modules utilize multi-path MS-M connectors with all fifty-two pins (SPST configuration) distributed across only two connectors, significantly speeding up plug-in and plug-out operations. The 40/42-590 and 65-290 model families utilize MMCX micro-miniature coaxial connectors with insulated housings, providing compact single ports that reduce wiring complexity and facilitate easy loop-through array size expansion.
The LXI 65-200 platform also allows users to load predefined test sequences and increment them using software or hardware triggers, reducing test times compared to standard software controller transactions. Sequences are stored on the LXI controller itself, reducing host CPU load and Ethernet traffic, and minimizing overall system latency. These features will optimize use in semiconductor testing, where many thousands of tests per DUT may be required.
Steve Edwards, Director of Switching Products at Pickering, comments: “All products employ high-quality, custom-designed, sputtered ruthenium reed relays manufactured by our relay division, Pickering Electronics. These switches feature an internal construction that maintains the necessary isolation for the new switched protection modules and ensures a long service life. Pickering also offers standard and custom cable solutions that can assist with integrating the products into users’ test systems.”
Pickering’s standard three-year warranty covers all modules.
