TDR (Ewe minen älleani fansoun) a fokkun äeä ewe radar. Ewe pisekin angang a tinalo eu esissin mi mwittir tori ewe kabel. Nupwen a churi ew impedance ese sopweno (usun ew fitikoko, fitikoko, fitikoko, ika nenien soposopono), kinikinin ewe pochokun a niwinsefan. Ewe pisekin angang a auku ewe fansoun sokkofesenin lefilen ewe pulse a tori me ewe fansoun a liwinsefal, me a fitifengen me ewe signal mi mwittir tori ewe medium, a aukuuku ewe towau ngeni ewe leenien fitikoko.

Ewe mwitirin an epwe fis signal a sokono non ekkewe sokkun media mi kabel (ewe pair mi fitikoko a kan fis non 0.6 ngeni 0.7 fansoun mwitirin ewe saram). Ewe fansoun pulse rise a affata ewe resolution non neni — ewe fansoun rise mi mwochomwoch a wewe ngeni resolution mi watte nge a mwochomwoch ewe ukukun towaw mi tongeni auku. Ewe watten me polarity an ewe signal mi pwa epwe tongeni aiti ngonuk ika pwe ka angang ngeni ew circuit mi suk (pwarano mi murino), ew circuit mi mwochomwoch (pwarano mi ngaw), ika impedance ese fiti (pwarano mi kukkun).
Non ekkewe pisekin kutta kabel ikenai, ewe angangen TDR a kan fiti ewe angangen aukuuku ukukun. FangService’s PK652 series ew tipeew ngeni ewe sokkun TDR — ese chok erenuk ika pwe ew kabel mei tongeni fiti, nge a pwan erenuk ukukun ukukun ewe kabel me ewe nenien fitikoko.
Non angangen aea, ewe tes TDR a mochen pwe ew kinikinin ewe kabel epwe tongeni tori (a riri ngeni ewe pisekin angang), nge nonomun ewe pwan ew kinikinin a atai ekkewe feiochun mecheresin. Ika ewe pwan ew kinikin a suk (ese much), ewe pisekin angang a kuna ew saram mi suk-circuit me a tongeni aukuuku unusen ukukun ewe kabel.
