In the previous edition of The Four Ws, I reviewed the fundamentals of adjacent channel power (ACP). This time I’m discussing the WHAT, WHY, WHEN and WHERE of harmonic distortion measurements. Measuring harmonic distortion will help you validate the proper functioning of your device’s components and, in turn, avoid interference with systems… (Show more)

This week’s post is guest authored by Charlie Slater, Business Development and Operations Manager for Keysight Services.   These days, most organizations operate within one of two scenarios: cutting costs while delivering the same topline, or holding costs steady while increasing revenues. The third, less-common scenario is investing more to… (Show more)

In a rock band, the drummer keeps the beat steady and the other musicians follow the rhythm. The drummer keeps the entire band in synch. The same concept is true when you integrate multiple instruments into a test system. The individual instruments need to be synchronized, especially when you are making multi-channel RF measurements. Like a… (Show more)

Originally posted Sept 25, 2013   Understanding when the errors will become a problem In this space, we’ve already talked about how the universe may be noisier than you think and described how noise adds something to all signal measurements. The Grinch’s distaste for noise was understandable, but it’s hardly a strategy for making better… (Show more)

As you walk through your lab, take a look at each RF bench. How old are your signal and network analyzers? How often are they kludged together to create one-off measurements? How recently have your engineers bugged you about getting new equipment that can actually test your latest RFIC?   I’m here to help you make a stronger case when your… (Show more)

Prove yourself as an engineer! The Schematic Challenge is the perfect opportunity to test your skills. On March 12, 13, and 14, we will be posting a new schematic or problem-solving challenge. If you, as a community, are able to answer questions 4, 5, and 6 correctly by Thursday, March 15 at 11:59 PM MST, we will add three 1000 X-Series… (Show more)

Helping You Achieve Greater Performance and Fast Measurement Speed At an exhibition demo booth, an engineer complained to me about the measurement speed of a PXI oscilloscope. To make a measurement, he programmed the data acquisition and post-analysis himself. The test took him over a minute to get each result. I told him that he didn’t have to… (Show more)

Like any RF engineer, there comes a time in your product’s design cycle that you need to test your device to make sure it’s behaving as you expect. There are different ways you can view your device’s signal, which brings us to why measuring signals in the time domain and frequency domain is the same, but not. This is because they both convey the… (Show more)

  Demystifying technology, and marking five years of The RF Test Blog For several years, I co-coached two middle school robotics teams. It was a great experience, and I learned at least as much as I taught—though generally about different subjects! Some of the kids gravitated toward the robot mechanisms, while others found a natural focus on the… (Show more)

  Fortunately, we can make things better—for your signal analyzer   Note from Ben Zarlingo: This guest post comes to us from Bill Scharf, a Keysight engineer with long experience in microwave signal analysis.   If you use even a gently aged spectrum analyzer, you may sometimes wonder why its amplitude accuracy above about 4 GHz is slightly worse… (Show more)
