Review: Tekbox TBCG4 harmonic comb generator

January 2, 2025 By Kenneth Wyatt Leave a Comment

Tekbox TBCG4 harmonic comb generator

The Tekbox TBCG4 harmonic comb generator produces a wide range of known frequencies for EMC immunity testing and routine checking of EMC chambers. I’ve used harmonic comb generators for decades in various applications, including antenna measurements, cable resonance measurements, and shielding-effectiveness testing. I also find them useful for checking the daily consistency of test chambers […]

How to calculate and apply an inverse FFT: part 1

December 12, 2024 By Rick Nelson Leave a Comment

The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain dataset. In early 2024, EE World published a series on the Fourier transform, which can convert a time-domain signal to the frequency domain (Figure 1, red arrow). The process is reversible (Figure […]

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 […]

New products at the EMC & Compliance International Conference

July 8, 2024 By Kenneth Wyatt Leave a Comment

At the annual UK event, Tekbox, Y.I.C. Technologies, and Harogic Technologies were among the companies exhibiting new EMC measurement equipment. The EMC & Compliance International conference and training was held again in Newbury, UK, from May 22 to 23 this year (Reference 1). This was my first opportunity to attend this annual conference hosted by […]

What’s the difference between a USB oscilloscope, spectrum analyzer, and digitizer?

December 4, 2023 By Jeff Shepard Leave a Comment

USB oscilloscopes are highly versatile instruments. With the right software, they can perform functions usually reserved for spectrum analyzers and digitizers. In some cases, however, special instruments are needed for optimal results. This FAQ compares the functions of oscilloscopes, spectrum analyzers, and digitizers with USB interfaces. They are called USB devices because they connect to […]

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’s all this triplen harmonics stuff?

January 20, 2022 By David Herres Leave a Comment

Unless your background is in ac power, it’s possible you haven’t run into the term triplen harmonic. Triplen harmonics have to do with the third harmonic. Even-numbered harmonics do not normally exist in power systems due to symmetry between the positive and negative halves of the ac cycle. It is the odd-numbered harmonics that engineers […]
