Discovering FFT Gating

 

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...]

Oh How I Hate to Commutate!

 

My favorite Sophomore in Engineering, Roger, and his group, made a small crane for their engineering project. It had many EMC issues.  One issue they had was noise from permanent magnet DC motors.  I am so glad Roger cares about this issue, because I have modeled a few permanent magnet DC motors, and I can explain how to design it so that then so they are … [Read more...]
