A day in the life: Five RF measurements for field engineers

June 22, 2021 By Lee Teschler Leave a Comment

A handful of basic techniques go a long way toward characterizing modern communication systems. Sarah Gross, Keysight Technologies Field engineers often find that every day presents its own special challenges. A typical work day may involve measuring a variety of devices or signals — cables, antennas, over-the-air 5G signals, or intermittent spurious signals. Successful completion […]

Single-sideband modulation and its measurement

June 14, 2021 By David Herres Leave a Comment

The most basic form of amplitude modulation is known as double-sideband AM, so called because mirror-image sidebands are produced above and below the carrier frequency. Early researchers found that they could use simple band-pass filters to eliminate one of the sidebands and even the carrier signal, improving the ratio of information-bearing power to total transmitted […]

Integration and differentiation operations and how they appear on a scope

May 28, 2021 By David Herres 1 Comment

Differentiate

Differential calculus is the study of rates at which quantities change. To find the derivative of a waveform at a specific point, we draw a tangent line through the point. The slope of the line, Δy/Δx, equals the derivative of the function at that point. Integral calculus quantifies the area bounded by a curve and […]

What is a load coil and how do you measure it?

March 2, 2021 By Lee Teschler 1 Comment

The textbook description of an inductor often involves a coil of wire. Of course, any material other than a perfect ideal insulator has theoretical inductance. All the windings do is multiply the effect by creating overlapping fields. It’s good to keep in mind that inductance is measurable in many non-coils, such as power transmission lines, […]

Trigger-and-decode scope setup handles 1000BASE-T1 automotive Ethernet

February 8, 2021 By Lee Teschler Leave a Comment

R&S scopes

The new K58 option for R&S RTO and R&S RTP scopes is billed as the world’s first triggering and decoding solution for 1000BASE-T1. The flexibility of Automotive Ethernet makes the simple twisted-pair network technology a candidate for an ever-increasing range of in-vehicle networks. To verify, commission and troubleshoot designs based on an Automotive Ethernet communication […]

Don’t get zapped — Using test instruments safely

January 21, 2021 By David Herres 1 Comment

safe scopes

Most engineers think they’ve minimized the chance of nasty surprises around the test bench when they’ve grounded their instruments and perhaps kept one hand in their pocket when working around high voltages. That said, there remain electrical hazards that are less obvious. They involve the electrical wiring and the environment around the lab. To begin, […]

When RMS amplitude is important and when it isn’t

November 20, 2020 By David Herres Leave a Comment

There are a variety of ways to specify the amplitude of a waveform. Here are a few of the most common forms and a primer on when specific types are most appropriate. In physics. amplitude is the absolute value of the maximum displacement from zero during one period of an oscillation. In electrical waveforms, amplitude […]

Current Digital Issue

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
