Experiments in Modern Physics Introductory Lab: Electromagnetic Pulses 1 Rex Tayloe Department of Physics, Indiana University 9/1/03 Last Revised: 9/24/03 Goal Become familiar with the principles of transmission, reflection, and attenuation of electromagnetic pulses in a coaxial cable. Introduction Many experiments involve the production and measurement of electrical pulses. One may wish to know their rate, distribution in amplitude, the relation of their occurrence times to those of other pulses, etc. Such measurements are done with ampliers, discriminators, multichannel analyzers, coincidence circuits, etc., which may or may not be working properly. It is essential, therefore, to gain facility in the use of test equipment such as pulse generators and oscilloscopes so that the performance of a pulse-measuring apparatus can be checked, point by point. Electrical pulses are piped around a laboratory via transmission lines of one sort or another, with consequent delays, attenuations, and reflections. It is important to understand these effects and to
