Evaluate the shielding effectiveness of flexible coaxial cables

SHIELDING effectiveness (SE) is an important fundamental parameter to consider when specifying flexible coaxial cables. Equally important as cable attenuation, shielding effectiveness determines the amount of isolation between cables and equipment that may be in close proximity ty to one another. Signal characteristics such as fidelity and crosstalk interference are minimized by properly selecting flexible cables with proper SE. However, there are multiple methods which can be used to measure shielding effectiveness. Controversy exists as to what the best method is. By understanding the various means by which shielding effectiveness is measured, it is a simple matter to determine the best method to use for its measurement. This paper looks at these measurement systems and other methods and presents what is believed to be the most accurate in terms of simulating a random BE environment with very low spurious or resonant effects.
