Noise figure measurement capability is available for Anritsu Company’s VectorStar MS4640 and ME7838A analyzers. Option MS4640A-041 equips VectorStar to be the only VNA family with 70 kHz to 125 GHz noise figure measurement based on a receiver optimized for measurements from 30 GHz to 125 GHz.
The MS4640A-041 option provides a wider noise figure measurement range and greater configuration flexibility. It features a simple, low-cost termination, rather than a specialized noise source, as part of the cold source noise figure measurement method.
The MS4640A-041 option is priced at $15,000 and is available in approximately 8 weeks ARO. The 125 GHz receiver, model SM 6609, is priced at $30,250 and available in approximately 16 weeks ARO.
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.
