Description: Here is a super=simple technique to use time-domain-reflectometry (TDR) with your scope, a battery and a resistor, to measure the length of coax, twisted pair wires, Ethernet cable (Cat5, Cat5e, Cat6, etc.), zip-cord, etc. Previous videos on transmission lines, reflections and TDR measurements are here: Transmission lines, reflections and terminations: youtube.com/watch?v=g_jxh0Qe_FY Basic TDR measurements with a scope: youtube.com/watch?v=Il_eju4D_TM Cheap TDR with Schmitt Trigger oscillator: youtube.com/watch?v=9cP6w2odGUc Notes from this video: qsl.net/w2aew/youtube/SimpleTDR.pdf
