IMS 2024 roundup: test equipment

July 17, 2024 By Martin Rowe Leave a Comment

Washington, DC — The 2024 International Microwave Symposium took place here in June at the Walter E. Washington Convention Center. As always, RF/microwave/mmWave test equipment was all over the exhibit hall. Frequency-domain test equipment — spectrum analyzers, vector network analyzers, power meters, and signal generators — were, of course, dominant. Other equipment, such as oscilloscopes […]

Should I use a spectrum, signal, or vector network analyzer? part 1

July 15, 2024 By Rick Nelson Leave a Comment

Signal analysis is invaluable for applications ranging from amplifier characterization to signal intelligence. In a recent series, we discussed specs such as 1-dB compression and third-order intercept points. At the end, I pointed to some application notes that explain how to use specific spectrum, signal, and vector network analyzers to make these measurements. These instruments’ […]

How can I quantify a device’s nonlinearity? part 1

June 5, 2024 By Rick Nelson Leave a Comment

Nonliearilty

You can specify nonlinearity in parts per million or, especially for RF components, in terms of the 1-dB compression point or third-order intercept point.

How to locate EMI emissions with near-field probes: Part 2

September 18, 2023 By Kenneth Wyatt 1 Comment

Near-field probe

Now that you know a little theory of near-field measurements, how do you use near-field probes and a spectrum analyzer to help you troubleshoot and mitigate emissions issues? Remember, as mentioned in Part 1, that deciding whether to use an H-field or E-field probe depends on whether you’ll be probing high switching currents — di/dt […]

IMS 2023 roundup: test equipment

July 3, 2023 By Martin Rowe Leave a Comment

Test equipment plays a major role in product development and production, which was apparent at IMS 2023. In the photos and videos below, you’ll get a taste of test developments at RF, mmWave, and sub-THz frequencies. This year, D-band (110 GHz to 170 GHz) seized a larger portion of the exhibit hall than in past […]

What are insertion loss and return loss and how can I measure them?

March 20, 2023 By Rick Nelson Leave a Comment

These basic RF measurements often uncover system problems in wired and wireless communications. If you observe a signal traveling from a source to a load through a passive system of some sort, you will notice that the signal attenuates by the time it reaches the load, and you will also notice that some of the […]

What is a Smith chart and why do I need one? (Part 2)

February 8, 2023 By Rick Nelson Leave a Comment

Smith chart

Take a journey around a Smith chart to find capacitance and inductance values in a matching network. Before computers became ubiquitous, the Smith chart simplified calculations involving the complex impedances found in RF/microwave circuits such as the one shown in Figure 1. That circuit includes a source with impedance Zs, transmission line with characteristic impedance […]
