EMI/EMC/SI/RF practical tips

Three real-world case studies show how RF power amplifiers and creative benchtop setups solve complex radiated immunity failures in hours instead of weeks. From military-grade testing to runaway medical motors, discover techniques that save time and money while identifying root causes traditional methods miss.

Resonances in components are a well-known topic for electronic designers when working in high frequencies (e.g. EMI/EMC). Do not forget to test your components with an impedance analyzer, especially if they are custom magnetic components.

Whenever an electronic circuit is first energized, transients occur in current and voltage waveforms. These start-up transients can affect the electrical and thermal behavior of components and circuits with serious reliability, EMI, and random effects. Try to characterize how your circuits start and stop.

Common mode currents are in the origin of many typical problems in EMI/EMC and RF electronics. The best way to understand those currents is to visualize them in your scope or spectrum analyzer.

Parasitic oscillations are a sneaky source of EMI/EMC failures. With the right layout and simple fixes—like reducing gain or breaking feedback loops—you can eliminate emissions without costly redesigns. Learn how to spot and stop these hidden troublemakers in your circuit.
