Today we take a crack at measuring some coax cable using TDR on an oscilloscope with the help of a pulse generator. Cable length can be calculated by sending a pulse down a cable and measuring how long it takes for the pulse to return.
If you don't have a pulse generator, here are a couple of cool little circuits from fellow KZitemrs:
