• Isiphetho

An i-analog TV transmitter is a Imishini yokusakaza ye-TV esetshenziselwa ukusakazwa kwe-TV emoyeni. Ikhanyisa amaza omsakazo athwala amasignali evidiyo namasignali alalelwayo ekumbozeni, futhi amele izithombe ezihambayo nomsindo ovumelanisiwe. 

Amandla e-analog TV transmitter ayahluka ukusuka ku-50w ukuya ku-10kw. Isakaza amasiginali we-TV ebangeni lefrikhwensi ye-VHF ne-UHF. Futhi isetshenziswa kabanzi eziteshini zokusakaza ze-TV ezahlukahlukene.

I-Analog TV transmitter ingenye yezingcezu ezibaluleke kakhulu zemishini yokusakaza ye-TV. Isetshenziselwa ukusakaza amasiginali we-TV kubamukeli be-TV ekukhaveni, futhi abantu bangawamukela ngothi oluthola i-TV.

Ngokuvamile, iqeda umsebenzi wokusakaza amasiginali we-TV ngezinyathelo ezi-3:

1. Ithola amasignali e-TV eziteshini ze-TV ngesixhumanisi se-studio transmitter.

2. Izocubungula amasignali e-TV futhi iwaguqulele amandla kagesi. Isibonelo, isidluliseli se-TV ye-analogi siguqule amasiginali we-TV kumagagasi esiphathi somsakazo ebangeni elithile lefrikhwensi.

3. Imali ye-elekthronikhi izodluliselwa ku-antenna esakaza i-TV futhi ikhiqize amaza omsakazo ngendlela yamasignali e-analog. I-antenna ye-TV yayizobasakaza.

Umsakazi we-TV we-analogi wekhwalithi engcono kakhulu ubalulekile ezinkampanini ezisakaza i-TV ngoba ukusakazwa kwe-TV kuyinkonzo yomphakathi ebalulekile eqinile nekhwalithi yokusakaza kwe-TV. Ngakho-ke ungasikhetha kanjani isidluliseli se-analog TV sesiteshi sakho somsakazo we-TV?

Ukusebenza kubalulekile. I-TV ye-analog enamandla amakhulu ingamboza ikhava enkulu. Umsebenzi omuhle kakhulu wevidiyo nomsindo unganikeza ababukeli umuzwa ongcono kakhulu wokulalela nokubuka. Umkhawulokudonsa omkhudlwana enawo, kulapho iziteshi eziningi ezingawudlulisa. Kusho ukuthi ungakwazi ukuheha ababukeli abaningi futhi ulethe izinzuzo ezengeziwe kubasakazi be-TV.

Nawa amapharamitha angu-3 angukhiye wesidluliseli se-TV ye-analog okufanele uwanake ngaphambi kokufaka ama-oda:

• Ukudlulisa Amandla - Amandla omsakazo we-TV anquma ukumbozwa kanye namandla okungena kwezimpawu ze-TV. Uma unemibuzo mayelana nokukhetha izinga lamandla, ungangabazi ukuthintana nochwepheshe wethu we-RF.

• Komkhawulokudonsa - I-bandwidth isho ububanzi befrikhwensi. Umkhawulokudonsa obanzi ungaqukatha ulwazi olwengeziwe, okusho ukuthi isidlulisi se-TV ye-analog singasakaza iziteshi eziningi ze-TV

• Ukucindezelwa kwe-Clutter kanye nokucindezelwa kwe-Harmonic - Ukucindezela imfuhlumfuhlu nokucindezelwa kwe-harmonic kunganciphisa izici ezingazinzile lapho isidlulisi se-TV ye-analogi sisakaza amasignali we-TV futhi sivikele umshini ekubhidlikeni. Ngakho-ke ukucindezelwa okuphansi kwe-clutter nokucindezelwa kwe-harmonic kungcono.

Akukhona nje ukusebenza okubalulekile, kodwa futhi ukuzinza kuyakwenza. Isidluliseli se-TV se-analog esithembekile singasakaza ngokuqhubekayo isikhathi eside futhi sigweme ukuphuka. Ngenxa yokuthi cishe akunakwenzeka ukuba ukwehluleka, kunganciphisa kakhulu izindleko zokusebenzisa abasakazi be-TV futhi kunikeze umuzwa ongcono kakhulu wokubuka wababukeli. 

Umsebenzi wokuphepha nokuvikela uyadingeka ku-TV ye-analog transmitter. Ukusebenza isikhathi eside kuvame ukuholela ezingeni eliphezulu lomonakalo emshinini. Ngaphandle komsebenzi wokuphepha nokuvikela, isidluliseli se-analogi ye-TV cishe siyophuka bese siholela ekulimaleni kwezinto ezisetshenziswayo ezizungezile.

Umklamo omuhle womkhiqizo kufanele ucabangele izidingo zabasebenzisi futhi ukwazi ukuthuthukisa ukusebenza kahle kwabo. Isibonelo, isikrini esicacile kanye nesixhumi esibonakalayo sokusebenza esiklanywe ngokunengqondo kungasiza kakhulu opharetha ukuthi bathole i-hang of the analog TV transmitter operation ngokushesha. Ngokusobala, kuyasiza ukuthuthukisa ukusebenza kahle kwabo.

Okokugcina, kufanele ukhethe uhlobo olungcono kakhulu olethembayo. Ibhrendi ethembekile ethembekile ingakunikeza isidlulisi se-TV se-analogi esingcono kakhulu futhi ithuthukise ukusebenza kahle kwezomnotho kwenkampani yokusakaza ye-TV.

Uma udinga usizo ngesidlulisi se-TV se-analogi noma esinye isisetshenziswa sokusakaza se-TV, singakunikeza ukwesekwa okufika ngesikhathi kanye nezeluleko eziwusizo kakhulu. Akungabazeki ukuthi uhlobo oluthembekile oluthembekile lunganciphisa izindleko nengcindezi yazo zonke izici zakho nganoma yisiphi isikhathi.

I-analog TV transmitter canungadlulisi amasignali e-TV ngaphandle kwezinye izinto zokusakaza ze-TV. Nalu uhlu lwemishini yokusakaza ye-analog TV. Ngokuvamile, yilezi:

• I-VHF&UHF i-analog TV transmitter
• I-antenna ye-TV
• Izintambo ze-Antenna
• Main ugesi
• Izixhumanisi
• Ezinye izesekeli ezidingekayo

Ngaphezu kwalokho, i-analog TV transmitter imvamisa ithola amasiginali we-TV eziteshini ze-TV ngesixhumanisi se-studio transmitter. Futhi uchungechunge oluphelele lwemishini yokuxhumanisa i-studio transmitter ngokuvamile luhlanganisa:

• I-Studio Transmitter link Transmitter
• Isamukeli sesixhumanisi sokudlulisa isitudiyo
• I-antenna ye-Studio Transmitter
• Izintambo ze-antenna
• Izixhumanisi
• Ezinye izesekeli ezidingekayo

Ukukhetha okukodwa akwanele, futhi udinga izinhlobo eziningi zezinketho? Nakhu okudingayo! Okulandelayo amabhrendi ambalwa ancintisanayo embonini yezokusakaza.

I-Rohde & Schwarz yasungulwa ngaphezu kweminyaka engama-85 futhi yaba ngomunye wabahlinzeki bemishini yokusakaza ye-TV abahamba phambili emhlabeni jikelele. Ithengisa isidlulisi se-TV esinamandla aphumayo asukela ku-10w kuya ku-96.5kw kanye nokusebenza kahle okungafika ku-50%. Ngokungeziwe kuma-transmitters we-TV, ihlinzeka ngochungechunge lwezixazululo zokuhlolwa kwe-RF nesilinganiso, ukusakaza, kanye nemidiya.

I-Continental Electronics ingumnikezeli wesistimu ye-RF nomkhiqizi oneminyaka engaphezu kwengu-70 yesipiliyoni. Igxila emandleni aphezulu kanye ne-high-frequency imishini yokusakaza emsakazweni. Izinga lemvamisa yesidlulisi se-TV yayo lisukela ku-kilohertz kuye ku-gigahertz, futhi izinga lamandla liyahlukahluka ukusuka kuma-watt kuya kumamegawathi.

I-Hitachi-Comark yinkampani ekhetheke kakhulu enesipiliyoni seminyaka eminingi ekukhiqizeni izingxenye ze-RF namasistimu e-RF okusakazwa kwe-TV nezingxenye ze-RF. Amandla okukhipha isidlulisi se-TV asukela ku-25w kuya ku-100kw. Ngaphezu kwalokho, inikeza ezinye izinto zokusebenza zokusakaza zomsakazo eziqeqeshiwe njengemishini yokufaka ikhodi, imishini yokuhlola ye-RF, njll.

I-Cable AML ingumkhiqizi wezinhlelo zokusakaza ochwepheshe futhi igxile ezinhlelweni zokusakaza ze-TV zedijithali kumafrikhwensi angu-50MHz kuya ku-80GHz. Imikhiqizo yayo ihlanganisa ama-transmitter we-TV angu-15W kuya ku-6.5kw kanye nama-transmitter angu-15W kuya ku-25kW FM, izixhumanisi ezikhomba-ephuzu zezinhlelo zokusebenza zevidiyo nedatha, ama-transceiver ama-microwave e-Broadband, ama-transmitters, abaphindayo, nabamukeli.
