  A single analyzer can cover 3 Hz to 110 GHz. Is that the best choice for you? I haven’t made many measurements at millimeter frequencies, and I suspect that’s true of most who read this blog. All the same, we follow developments in this area—and I can think of several reasons why. First, these measurements and applications are getting a lot of… (Show more)

  Honing your engineering skills and staying alert for serendipity The signals we deal with continue to become more complex and challenging. So do the standards that govern them and the measurements those standards specify. It’s a trend that shows no sign of slowing, and perhaps it’s some comfort that this trend is a source of intellectual… (Show more)

  Are lifetime and performance ratings wrong, or is it measurement practice? A guest post to the RF Test Blog from Keysight’s Michael Lux A while back, Ben discussed the potential for one type of connector damage and supplied a pretty good example: Damage to the collet or female center conductors of two 2.92 mm K connectors has rendered them… (Show more)

  Don’t sacrifice the benefits of improved equipment by missing the basics Just a decade ago I would have found it hard to believe, but millimeter-frequency applications above 50 GHz are going genuinely mainstream. Wireless HD, 802.11ad wireless networking, 5G cellular, and automotive radar are high-profile examples of an important trend,… (Show more)

Originally posted Oct 4, 2016 Sometimes the answer is not in the first place you look Real-time spectrum analyzer (RTSA) capability has gradually moved from a specialized measurement made by specialized instruments to an option available for many spectrum and signal analyzers. Keysight recently added an RTSA option to FieldFox handheld analyzer… (Show more)

Originally posted Sept 21, 2016   No—but the way forward has implications for RF and microwave testing In Electronic Design, Lou Frenzel recently asked a couple of provocative questions, and in this post I’d like to look at both from a different angle (I previously discussed one in the context of engineering imagination). Specifically, Lou… (Show more)

Originally posted Aug 24, 2016   Sometimes a common understanding is not common   It’s always an interesting experience when I find that one of my assumptions is wrong, or at least not very right. Yes, it’s a chance to learn and grow and all that, but it sometimes provokes puzzlement or a little disappointment. This is one of those puzzling and… (Show more)

Originally posted Aug 9, 2016   Different ways to get your signal bits   There’s a long history of synergy and a kind of mutual bootstrapping in the technology of test equipment and the devices it’s used to develop and manufacture. Constant technology improvements lead to welcome—and sometimes crucial—improvements in RF performance. It’s a… (Show more)

Originally posted Jul 22, 2016   An overview to complement your equations   After some recent conversations about noise figure measurements, I’ve been working to refresh my knowledge of what they mean and how they’re made. My goal was to get the essential concepts intuitively clear in my mind, in a way that would persist and therefore guide me… (Show more)
