An cholumikizira TV cha analogi ndi Zida zoulutsira pa TV amagwiritsidwa ntchito kuwulutsa pa TV pa TV. Imawunikira mafunde a wailesi omwe amanyamula ma siginecha amakanema ndi ma siginecha amawu kuti awonetsedwe, ndipo amayimira zithunzi zosuntha ndi mawu olumikizidwa. 

Mphamvu ya transmitter ya analogi TV imasiyanasiyana kuchokera ku 50w mpaka 10kw. Imawulutsa ma siginecha a TV mumitundu yosiyanasiyana ya VHF ndi UHF. Ndipo amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana otumizira ma TV.

Analogi TV transmitter ndi chimodzi mwazinthu zofunika kwambiri pazida zowulutsira pa TV. Amagwiritsidwa ntchito poulutsa ma siginecha a pa TV kwa olandila ma TV omwe akuwonetsedwa, ndipo anthu amatha kuwalandira kudzera pa TV akulandila mlongoti.

Nthawi zambiri, imamaliza ntchito yowulutsa ma siginecha a TV munjira zitatu:

1. Imalandila ma sigino a TV kuchokera kumawayilesi a TV kudzera pa ulalo wa situdiyo wopatsirana.

2. Idzakonza ma siginolo a TV ndikuwasintha kukhala magetsi. Mwachitsanzo, chowulutsira pa TV cha analogi chinasinthira ma siginecha a TV pa mafunde onyamula wailesi pamlingo wina wake.

3. Ndalama zamagetsi zidzasamutsidwa ku mlongoti wotumizira ma TV ndikupanga mafunde a wailesi monga zizindikiro za analogi. Mlongoti wa pa TV ukanawaulutsa.

Chowulutsira pa TV cha analogi chapamwamba kwambiri ndichofunikira kwa makampani owulutsa pa TV chifukwa kuwulutsa kwa TV ndi ntchito yofunika kwambiri yapagulu yomwe imakhala yokhwima ndi mtundu wa kuwulutsa kwa TV. Ndiye mungasankhire bwanji cholumikizira chabwino kwambiri cha analogi pa TV yanu?

Kuchita ndikofunika. Chowulutsira TV cha analogi chokhala ndi mphamvu zambiri chimatha kuphimba chophimba chachikulu. Kanema wabwino kwambiri komanso womvera amatha kupatsa owonera mwayi womvera komanso kuwonera. Kuchuluka kwa bandiwifi yomwe ili nayo, njira zambiri zomwe zimatha kutumiza. Zikutanthauza kuti mutha kukopa owonera ambiri ndikubweretsa zabwino zambiri kwa owulutsa pa TV.

Nawa magawo atatu ofunikira a TV ya analogi yomwe muyenera kusamala musanayitanitse:

• Kutumiza Mphamvu - Mphamvu ya chowulutsira TV imasankha kuphimba ndi kuthekera kwa kulowa kwa ma sigino a TV. Ngati muli ndi mafunso okhudza kusankha kwa mphamvu yamagetsi, musazengereze kulumikizana ndi katswiri wathu wa RF.

• bandiwifi - Bandwidth imatanthawuza kukula kwafupipafupi. Bandiwifi yokulirapo imatha kukhala ndi zambiri, zomwe zikutanthauza kuti chowulutsira TV cha analogi chikhoza kuwulutsa ma TV ambiri

• Kuponderezedwa kwa Clutter ndi Harmonic Suppression - Kuponderezedwa kwa Clutter ndi kutsekemera kwa harmonic kungathe kuchepetsa zinthu zosakhazikika pamene wofalitsa wa TV wa analogi amawulutsa zizindikiro za TV ndikuteteza makina kuti asawonongeke. Chifukwa chake kuponderezana kwapang'onopang'ono ndi kuletsa kwa harmonic kuli bwino.

Sikuti magwiridwe antchito ndi ofunika, komanso kukhazikika kumachita. Chotulutsa chodalirika cha TV cha analogi chimatha kuulutsa mosalekeza kwa nthawi yayitali ndikupewa kusweka. Chifukwa ndizosatheka kukhala wolephera, zitha kuchepetsa mtengo wogwiritsa ntchito owulutsa pa TV ndikupereka mwayi wowonera bwino kwambiri kwa owonera. 

Chitetezo ndi chitetezo ndichofunikira pa cholumikizira TV cha analogi. Kugwira ntchito nthawi yayitali nthawi zambiri kumabweretsa kuwonongeka kwakukulu pamakina. Popanda chitetezo ndi chitetezo, chowulutsira TV cha analogi mwina chimasweka ndikupangitsa kuwonongeka kwa zida zozungulira.

Mapangidwe abwino azinthu ayenera kuganizira zosowa za ogwiritsa ntchito ndikutha kuwongolera magwiridwe antchito awo. Mwachitsanzo, chinsalu chowonekera bwino komanso mawonekedwe opangidwa bwino angathandize kwambiri ogwira ntchito kuti azitha kuyang'anira ntchito yotumizira ma analogi pa TV mwachangu. Mwachiwonekere, ndizothandiza kuwongolera magwiridwe antchito kwa iwo.

Pomaliza, muyenera kusankha mtundu wabwino kwambiri womwe mumadalira. Mtundu wodalirika wodalirika ukhoza kukupatsirani makina abwino kwambiri otumizira ma TV a analogi ndikuwongolera magwiridwe antchito amakampani owulutsa pa TV.

Mukafuna kuthandizidwa ndi chowulutsira TV cha analogi kapena zida zina zoulutsira pa TV, zitha kukupatsani chithandizo chapanthawi yake komanso malangizo othandiza kwambiri. Palibe kukayika kuti mtundu wodalirika wodalirika ukhoza kuchepetsa mtengo ndi kupanikizika kwazinthu zonse kwa inu nthawi iliyonse.

Chowulutsira TV cha analogi chingatheosatumiza ma siginecha a TV popanda zida zina zowulutsira pa TV. Nawu mndandanda wa zida zowulutsira pa TV za analogi. Mwambiri, iwo ndi:

• VHF&UHF analogi TV transmitter
• TV yotumizira mlongoti
• Zingwe za Antenna
• Main magetsi
• zolumikizira
• Zina zofunika zowonjezera

Kuphatikiza apo, chowulutsira TV cha analogi nthawi zambiri chimalandira ma siginecha a TV kuchokera kumawayilesi a TV kudzera pa ulalo wapa studio. Ndipo zida zathunthu zolumikizira ma studio amaphatikizanso:

• Kutumiza ulalo kwa studio transmitter
• Wolandila ulalo wa studio transmitter
• Mlongoti wolumikizana ndi studio transmitter
• Zingwe za mlongoti
• zolumikizira
• Zina zofunika zowonjezera

Kusankha kumodzi sikokwanira, ndipo mukufuna mitundu yambiri pazosankha? Izi ndi zomwe mukusowa! Zotsatirazi ndi zina mwazinthu zomwe zimapikisana pamakampani owulutsa.

Rohde & Schwarz adakhazikitsidwa zaka zopitilira 85 ndipo adakhala m'modzi mwa ogulitsa zida zabwino kwambiri zowulutsira pa TV padziko lonse lapansi. Imagulitsa chowulutsira TV chokhala ndi mphamvu zotulutsa kuyambira 10w mpaka 96.5kw mpaka 50% yogwira ntchito bwino. Kuphatikiza pa ma transmitter a TV, imapereka mayankho angapo a mayeso a RF ndi muyeso, kuwulutsa, ndi media.
