Setlama-lehlakore sa 75 ohms ke mofuta oa setlama-lehlakore se bitsoang impedance ea sona ea 75 ohms.

Ke karolo e sa sebetseng e sebediswang ho laola matla a letshwao la potoloho, Sethibela-matla sa 75Ω se thibela ho hodiswa le ho sotheha ho feteletseng ha letshwao, mme se thibela ho hloleha ho bakwang ke ho fetella ha letshwao.

Litšobotsi tsa mantlha tsa li-attenuator tse tsitsitseng tsa 75Ω li kenyelletsa:

1. Ho bapisa Impedance: Impedance ea attenuator e tsitsitseng ea 75 Ohms e ts'oana le impedance e ikhethang ea mohala oa phetiso ea lets'oao oa lisebelisoa tsa video, phatlalatso ea thelevishene le sistimi ea thelevishene ea cable, ka hona e fokotsa ho bonahatsa le ho lahleheloa ke lets'oao la phetiso.
2. Ho sotha ho tlase: Sethibela-matla se ka fokotsa matla a lets'oao ntle le ho hlahisa ho sotha ho eketsehileng kapa tšitiso ea lets'oao.
3. Ho tšepahala ho hoholo: Ka lebaka la hore li-attenuator ke likarolo tse sa sebetseng 'me ha li na likarolo tse tsamaeang, li tšepahala haholo 'me ha li hloke tlhokomelo kapa ho nkeloa sebaka.

Li-attenuator tsa 75 ohms li sebelisoa hangata lits'ebetsong tse latelang:

1. Marangrang a thelevishene ea cable le marangrang a thelevishene ea dijithale, e sebelisoa ho laola matla a lets'oao le ho fokotsa ponaletso le tahlehelo ea lets'oao.
2. Nakong ea tlhahiso le phetiso ea livideo tsa qeto e phahameng le tsa tlhaloso e phahameng, laola matla a lets'oao 'me u boloke boleng ba phetoho.
3. Litsamaisong tsa phetiso ea matšoao a phatlalatso le thelevishene, lisebelisoa tse fetolang matla a matšoao ho lumellana le ts'ebetso e itseng ea matšoao a ajoang le ho atolosa mefuta ea matšoao.
4. Li-antenna tsa thelevishene, li sebelisoa ho leka-lekanya matla a lets'oao pakeng tsa li-amplifier le li-antenna.

QualwaveE fana ka li-attenuator tse fapaneng tsa coaxial tse nepahetseng haholo le tse nang le matla a phahameng tsa 75 ohms tse koahelang maqhubu a DC ~ 3GHz, li ka bapisoa le lihokelo tsa BNC, F-type, le N-type. Attenuation e fapana haholo-holo ho tloha ho 1 ho isa ho 40dB. Li-attenuator tse nang le ho nepahala ho hoholo le matla a phahameng, boleng bo tšepahalang, lihlahisoa tse ngata li latela ROHS, li ka fihlela litlhoko tse fapaneng tsa bareki.
