- Isinyathelo sesi-3: Xhuma kabusha ikhebula lokuqala ebhokisini lekhebula.
- Isinyathelo sesi-4 Xhuma ikhebula imitha yesiginali noma isihloli sekhebula le-coaxial.
- Isinyathelo sesi-5: Naka Inani Lamandla Esiginali
- Isinyathelo 6. Phinda izinyathelo ezimbili kuya kwezinhlanu ngobude bekhebula le-coax kunethiwekhi yakho.

Kulesi sihloko, ngizokufundisa ukuthi ungabheka kanjani amasiginali kuzintambo ze-coaxial.
Emsebenzini wami, kwakudingeka ngihlole njalo ukuthi isignali ye-coax yayisebenza kahle noma cha ukuze ngiqinisekise isivinini esihle se-inthanethi nokuxhumeka. Lapho ikhebula le-coaxial liguga, ukusebenza kwazo zombili izinhlelo zethelevishini nezamakhompyutha kuncipha, okungaholela ekuhlulekeni kwazo.
Ngokuvamile, akunzima ukuhlola isignali yekhebula le-coaxial. Landela lezi zinyathelo:
- Hlola izinga lesiginali emthonjeni
- Qaphela amandla esiginali yokuqala njengamandla ayisisekelo esiginali
- Xhuma kabusha ikhebula lokuqala ebhokisini lekhebula
- Xhuma ikhebula imitha yesiginali
- Naka inani lezinga lesignali kusibonisi sesignali.
- Phinda izinyathelo 2 ukuya kwezi-5 ngobude bekhebula le-coax kunethiwekhi yakho.
Ngizohlola okwengeziwe ngezansi.
Ukuhlolwa Kwekhebula Le-Coaxial
Lezi zinyathelo ezinemininingwane zizokusiza ukuthi uhlole amandla esignali wekhebula yakho ye-coax.
Isinyathelo 1: Izinga Lomthombo
Hlola izinga lesignali yomthombo.
Landelela isistimu yakho yekhebula kuze kufike lapho ixhuma khona kunethiwekhi yangakini. Nqamula ikhebula le-coax ohlangothini lwenethiwekhi lwebhokisi bese uyixhuma imitha yesignali yekhebula noma isihloli se-coax.
Isinyathelo sesi-2. Maka amandla esignali yokuqala njengamandla esignali eyisisekelo.
Rekhoda izinga lesiginali yomthombo njengeleveli yesisekelo.
Imitha yakho ibonisa ileveli yesiginali kuma-decibel millivolts (dbmV). Amamitha edijithali angashintsha ngokuzenzakalelayo phakathi kwama-oda obukhulu, abike amakhulu noma izinkulungwane ze-dBmV ezingeni elifanayo lokuphumayo, ngakho-ke naka isikali izilinganiso zamamitha.
Isinyathelo sesi-3: Xhuma kabusha ikhebula lokuqala ebhokisini lekhebula.
Xhuma kabusha ikhebula lokuqala ebhokisini lekhebula bese ulilandela liye ekugcineni. Lokhu kungenzeka empambanweni yomgwaqo, i-TV noma imodemu.
Isinyathelo sesi-4 Xhuma ikhebula imitha yesiginali noma isihloli sekhebula le-coaxial.
Nqamula ikhebula kutheminali exhunywe kuyo bese uyixhuma kumitha yamandla esignali.
Isinyathelo sesi-5: Naka Inani Lamandla Esiginali
Linganisa izinga lesiginali.
Ngisho noma ukonakala kwesignali kancane kulindelekile kukhebula, amandla esiginali yakho kufanele afane nokufundwa kwakho kwesisekelo. Uma kungenjalo, ikhebula le-coaxial kufanele lishintshwe.
Isibani esibomvu sisho ukuthi ikhebuli ilungile.
Isinyathelo 6. Phinda izinyathelo ezimbili kuya kwezinhlanu ngobude bekhebula le-coax kunethiwekhi yakho.
Phinda izinyathelo 2 ukuya ku-5 ngobude bekhebula elikhoaxial kunethiwekhi yakho ukuze uhlukanise inethiwekhi yekhebula esele.
Amandla esignali ehla ngobude be-hop ngayinye nobude bekhebula, kodwa noma yikuphi ukuwohloka okuphawulekayo kubonisa ukuhlukana noma ukwehluleka kwekhebula. Ukugcina ubuqotho besignali, lezi zintambo ezinephutha nezihlukanisi kufanele kushintshwe. (1)
Iqhinga Elingcono Kakhulu Lokulandela Nokuhlola Ikhebula le-Coax
Ukuze ulandelele futhi uhlole ikhebuli ye-coaxial, ungasebenzisa ithuluzi lobunikazi nelijwayelekile elizokwenza lula futhi lisheshise umsebenzi wakho. Ngifake ulwazi oluthile mayelana nesihloli sekhebula le-coax esingcono kakhulu nesihloli ukwenza izinto zibe lula.

- Ingakwazi ukuhlola ukuqhubeka kwekhebuli ekhoaxial futhi ibonise ikhebula ezindaweni ezine ezihlukene ngesikhathi esisodwa.
- Iphuma nesilawuli kude esinombala esinekhodi ukuze sibonakale kalula.
- Izinkomba ze-LED zibonisa ukuba khona kwesifunda esifushane, ukuphuka noma impilo yekhebula le-coaxial.
- Inomklamo ongasindi futhi ohlangene ongena kalula ephaketheni lakho.
- Isibambo esikahle sisiza ukuthwala nokusebenza.
Ukufingqa
Ngethemba ukuthi lo mhlahlandlela uzokusiza ukuthi ugade futhi uhlole ikhwalithi yesiginali yekhebula le-coax ukuze uthole isivinini namandla e-inthanethi aphelele. Inqubo ilula futhi ayidingi uchwepheshe ukuze ayenze; vele ulandele izinyathelo engizinikezile. (2)
