Jitter is one of the most common things we need to measure these days. I investigated how far I can get using only a mid-range scope's histogram. Reasonably far, it turns out.
We've discussed a lot of jitter here at Scope Junction, ranging from gigabit data to megahertz clocks (see some links below), and in most cases, one expects to need a high-end scope to make meaningful measurements. But with a midrange Tek MDO scope at my disposal, I wanted to see what measurements I could make with it, even though it doesn't explicitly support jitter analysis.
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.
