Conducted emissions from LED light fixtures at frequencies from 1 MHz to 30 MHz can interfere with amateur radio and several broadcast bands. Radiated emissions reach into the lower cellular bands. After recently moving to northern Colorado and setting up my EMC lab and amateur radio station in the basement, I wanted to update the […]

Review: 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 […]
Modulated RF power amplifiers for EMC pre-compliance testing
The TekBox TBMDA3 and TBMDA4 Modulated Wideband Power Amplifiers have been specifically designed to provide an economical signal source for immunity testing of electronic circuits and products. While these amplifiers are intended to increase the output of a spectrum analyzer’s tracking generator, they are also useful as general-purpose wideband RF signal amplifiers. The TBMDA3 and […]
