The LinkRunner AT from Fluke Networks performs six essential Ethernet connectivity tests and returns results in less than 10 seconds. Optimized for speed and simplicity, the LinkRunner AT has a profile function that enables custom test sets.
Designers can verify the signal and link integrity of connections at 10 Mbps, 100 Mbps, and 1 Gbps on copper or fiber. The six connectivity tests performed with the AutoTest feature include continuity, link speed and duplex, DHCP and DNS server availability and performance, ping and TCP port connectivity using IPv4 and IPv6, nearest switch and port identification, and Power over Ethernet loading (copper only).
Users can also store up to 50 test results and download them to a PC. The device is equipped with a 2.8-in. color VGA display, a 12-key elastomeric keypad, and a rechargeable lithium-ion battery that provides up to 6 hours of operation. A mini USB port allows software upgrades in the field.
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.
