EMC Units in Measurements and Testing

This article reviews the decibel units used in EMC laboratory measurements and testing. We begin by defining a decibel (dB) unit and proceed to the EMC specific units for voltage, current, power, and impedance measurements.

Impedance of the Four Passive Circuit Components: R, L, C, and a PCB Trace

This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace.

S-Parameters Tutorial – Part II: EMC Measurements and Testing

This part II of the s-parameter tutorial presents several examples of the s-parameter use in EMC measurements and testing.

Impact of a Trace Length on Capacitor Frequency Response

In this article we investigate the frequency behavior of a ceramic capacitor.

Common-Impedance Coupling Between Circuits

For common-impedance coupling to occur, two circuits must share a current path (with a non-negligible impedance)

Topology and Characterization of a DC Line Impedance Stabilization Network

This article discusses the topology and characteristics of a dc Line Impedance Stabilization Network (LISN), often referred to as an Artificial Network (AN).

Alternative Paths of the Return Current

Consider a two-sided PCB with a single trace on top and full copper ground plane on the bottom.

Crosstalk Reduction Between PCB Traces

When two circuits are in the vicinity of one another, a signal propagating in one circuit can induce a signal in another circuit, due to capacitive (electric field) and/or inductive (magnetic field) coupling between the circuits. This phenomenon is referred to as crosstalk.
