Modular instrumentation -- PCIe, PXI, and PXIe -- continue to find applications in test and measurement. While production test is still the mainstay of PXI/PXIe, some stand-alone instruments now have PXI under the hood. PCIe instruments boards are alive and well, too.
The last few months have brought several new modular instrument cards, chassis, and controllers to the market. You can view them over the next several pages, grouped by category.
Capable of switching up to 300 VDC/300 VAC and 2 A, the SMX-3276 3U PXI Express multiplexer from VTI Instruments furnishes 152 channels for scanning multiple points to a common bus in 1-wire, 2-wire, or 4-wire configurations.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
