This article is devoted to the radiated emissions measurements. These measurements can be performed either at the Open Area Test Site (OATS) or in an Absorber-Lined Shielded Enclosure (ALSE).
Foundations Consider the transmission line circuit shown in Figure 1. A sinusoidal voltage source with its source impedance drives a lossless transmission line with characteristic impedance ZC, terminated in... Read More...
This article focuses on the current probes used in EMC measurements and testing.
This article describes the voltage method of the conducted emissions measurements.
This article discusses the topology and characteristics of a dc Line Impedance Stabilization Network (LISN), often referred to as an Artificial Network (AN).
Consider a spherical capacitor consisting of two concentric, conducive spheres separated by a dielectric.
Reducing the duty cycle (the pulsewidth) reduces the low-frequency spectral content of the waveform, but does not affect the high-frequency content.
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.
In this article, we consider the effects of a discontinuity along the transmission line which occurs when the transmission line characteristic impedance changes.
