  Electrical engineers lead the way Years ago, a manager of mine seemed to constantly speak in analogies. It was his way of exploring the technical and business (and personal!) issues we faced, and after a while I noticed how often he’d begin a sentence with “It’s like...” His parallels came in a boundless variety, and he was really creative in… (Show more)

  The difference can be anything from 0 dB to infinity Most RF engineers are aware that signal measurements are always a combination of the signal in question and any contributions from the measuring device. We usually think in terms of power, and power spectrum has been our most common measurement for decades. Thus, the average power reading at a… (Show more)

  Good news about RBW, noise floor, measurement speed, and finding hidden signals Some things never change, and others evolve while you’re busy with something else. In recent years, RF measurements provide good examples of both, especially in signal analysis fundamentals such as resolution bandwidth filtering, measurement noise floor, and speed or… (Show more)

A few months ago, Keysight’s Brad Frieden and I both wrote about downconversion and sampling, related to wireless and other RF/microwave signals. Brad's article in Microwaves & RF appeared about two weeks before my blog post, though I somehow missed it. His main focus was on oscilloscopes and improving signal-to-noise ratio (SNR) in measurements… (Show more)

  Wrestling information from a hostile universe I can’t make a serious case that the universe is actively hostile, but when you’re making spurious and related measurements, it can seem that way. In terms of information theory, it makes sense: The combination of limited signal-to-noise ratio and the wide spans required mean that you’re gathering… (Show more)

  Jet engines, furry hoods, and a nod to four years of the Better Measurements blog This blog gives me occasional freedom to explore technology and phenomena that have only a peripheral relationship to RF design and measurement. Sometimes it feels like a permission slip to cut class and wander off to interesting places with remarkable analogs to… (Show more)

  Taking advantage of knowledge your signal analyzer doesn’t have To respect the value of your time and the limits of your patience, I try to keep these posts relatively short and tightly focused. Inevitably, some topics demand more space, and this follow up to December’s post Exchanging Information You’ve Got for Time You Need is one of those.… (Show more)

  An unacknowledged “borrowing” Few things in technology are completely original, “from the ground up” innovations. Of course, that’s no knock on those who creatively move technology forward, whether they’re making a new idea practical, applying existing technology in a new area, or fixing the multitude of problems that always crop up. All of us… (Show more)

Make better measurements by using all the information you can get Some of the things we do as part of good measurement practice are part of a larger context, and understanding this context can help you save time and money. Sometimes they’ll save our sanity when we’re trying to meet impossible targets, but that’s a topic for another day. Take, for… (Show more)
