  Handling the frequency and bandwidth challenges of 5G, radar, and more 5G technologies and markets are much in the news these days, and for good reasons. The economic potential is large, the opportunities are relatively near-term, and the technological challenges are just the kind of thing RF engineers can get excited about. Whether your focus… (Show more)

  As technologists, we need ways to tell the difference Over the past few months I’ve been hearing more about a propulsion technology called an EM Drive or EMDrive or, more descriptively, a “resonant cavity thruster.” As a technology that uses high-power microwaves, this sort of thing should be right in line with our expertise. However, that… (Show more)

  Refining your design and creating happy customers   Note from Ben Zarlingo: I invite you to read this guest post by Nick Ben, a Keysight engineer. He discusses the what, why, when and where of spurious emissions before delving into the importance of identifying them in your device’s transmitting signal and thereby improving your product design.… (Show more)

  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)
