Time Domain Reflectometry Theory
For Use with Keysight 86100 Infiniium DCA
The most general approach to evaluating the time domain response of any electromagnetic system
is to solve Maxwell's equations in the time domain. Such a procedure would take into account all the
effects of the system geometry and electrical properties, including transmission line effects. However,
this would be rather involved for even a simple connector and even more complicated for a structure
such as a multilayer high-speed backplane. For this reason, various test and measurement methods
have been used to assist the electrical engineer in analyzing signal integrity.
The most common method for evaluating a transmission line and its load has traditionally involved
applying a sine wave to a system and measuring waves resulting from discontinuities on the line.
From these measurements, the standing |
