APEC 2025 test equipment: oscilloscopes and probes

March 24, 2025 By Martin Rowe Leave a Comment

oscilloscope and probes in power electronics

Oscilloscopes and probes play a vital role for engineers designing and testing power electronics. Delivering electrical power to analog and digital circuits and systems is more than just DC measurements. That’s because nearly all power-converter circuits use switching techniques to maximize efficiency. Silicon carbide (SiC and gallium nitride (GaN) transistors, with their higher voltage and […]

Review: PCBite circuit board holder and probe kit

January 24, 2025 By Kenneth Wyatt Leave a Comment

The PCBite kit holds your circuit board in place while you probe it, reducing the risk of short circuits. Recently, I’ve had to test and characterize many small PC boards, including embedded processors, DC-DC converters, and other wireless-related products, for EMC issues. I’ve never really had an easy way to keep these boards from moving […]

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 […]

Should I use a spectrum analyzer, signal analyzer, or vector network analyzer? Part 4

August 19, 2024 By Rick Nelson Leave a Comment

A vector network analyzer can fully characterize components by deriving their scattering parameters. In earlier parts of this series, we looked at analog spectrum analyzers (part 1 and part 2) and vector signal analyzers (part 3), both of which monitor unknown signals, whether emanating from a system, device under test (DUT), or an enemy’s transmitter […]

APEC 2024: Test equipment

March 14, 2024 By Martin Rowe Leave a Comment

Test equipment is everywhere. Every trade show has it regardless of the focus. Power is no exception. At APEC 2024, EE World visited several booths displaying test equipment: meters, oscilloscopes, source-measure units (SMUs), bench power supplies, and electronic loads. The photos and videos below highlight what we saw, presented in alphabetical order by company. In […]
