Abstract
An adaptive pulse width (APW) Time Domain Reflectometer (TDR) comprises an enhancement to the standard Pulse TDR by adjusting the effective pulse width as a function of time. Improved resolution for a large range of cable lengths is obtained, as well as allowing an all-in-one view of the processed return signal trace.
