This month, I will explain one of the most useful functions you can find in the Rohde & Schwarz RTO family of digital scopes (Fig. 1): the FFT gating function. This is a function I like to use in the demonstrations included in many of my courses and seminars. Fig. 1. An RTO digital scope (photo courtesy R&S] The RTO family of digital scopes is ideal for EMI … [Read more...]
Review of MIL-STD-461 RS101– Radiated Susceptibility, Magnetic Field and RS103 Radiated Susceptibility, Electric Field
Introduction This article discusses RS101 and RS103, including the updates contained in MIL-STD-461 revision “G”, the current revision. These tests quantify the ability of a device to tolerate undesired signals present as a field at the device and associated cables. The field has the potential of coupling the interference into the device circuitry and cause performance … [Read more...]

Basic EMI Concepts
Understanding EMC is all about two important concepts: (1) all currents flow in loops and (2) high frequency signals are propagated as electromagnetic waves in transmission lines and the field energy travels through the dielectric. The two concepts are related because they are intertwined together. Digital signals create the propagating field, which induces the convection … [Read more...]
