    Time Domain Reflectometry (TDR) is a convenient way to evaluate impedance values and variations along a transmission line such as cables, connectors or a microstrip on a PC board. At speeds of less than 1Gbps, transmission quality can be analyzed in time domain just as the signal integrity of data signals is often analyzed in time domain. Impedance tolerances are contained in the electrical specifications for many of today's digital system components, such as Rambus, USB, Firewire, and many more. If these tolerances are violated, signal integrity issues become apparent.
