  Taking extra care in the lands of the large and the small Recently, I found myself peering at a dial indicator while checking the blade runout on my shiny new 12-inch miter saw. I’m putting up new trim in my house, and the big blade allows me to make some cuts directly on larger assemblies. However, I’m no professional woodworker, so my motto is… (Show more)

  The case of the troublesome garage door opener   Note from Ben: This is the first in a series of guest posts from Jennifer Stark of Keysight. As discussed here earlier, our increasingly crowded RF environment will result in more interference, and a higher likelihood of it causing problems. To stay ahead of them, you’ll need your creativity,… (Show more)

  Engineers that exemplify creativity, and the ability to explain it School is out and some are on holiday. It’s a good time to briefly widen this blog’s technology focus a bit with one of my occasional off-topic wanderings. This time we’ll look at impressive achievements of some engineers of yore, and a couple of enlightening explanations of… (Show more)

  Coherence can make a big difference Sometimes The Fates of Measurement smile upon you, and sometimes they conspire against you. In many cases, however, it’s hard to tell which—if either—is happening. More often, I think, they set little traps or tests for us. These are often subtle, but nonetheless important, especially when you’re trying to… (Show more)

  A quick, intuitive look at what will make them challenging Noise is fundamental in much of what RF engineers do, and it drives cost/performance tradeoffs in major ways. If you’ve read this blog much, you’ve probably noticed that noise is a frequent focus, and I’m almost always working to find ways to reduce it. You’ve also noticed that I lean… (Show more)

  If you're going to optimize it you have to quantify it   Note from Ben Zarlingo: This is the second in our series of guest posts by Nick Ben, a Keysight engineer. Here he turns his attention to the fundamentals of noise figure.   In the previous edition of The Four Ws, I discussed the fundamentals of spurious emissions. This time I’m discussing… (Show more)

  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)
