I-actenuator engu-75 ohms uhlobo lwe-actenuator ogama layo lokuvinjwa kwalo kwama-ahms angama-75.

Yingxenye engenasisekelo esetshenziselwa ukulawula amandla wesiginali wesekethe, i-75ω Ateator ivimbela ukukhuliswa ngokweqile kanye nokuhlanekezela kwesiginali, futhi kuvimbela ukwehluleka okubangelwa ukulayisha ngokweqile kwesiginali.

75 Izinhlelo ezi-Attenuators eziphambili zifaka:

1. Ukuqhathanisa okufanayo: Ukuvinjwa kwe-attenuator e-attenuator engu-75 ohms kufana nokuvinjwa kwesimo somugqa wokuhambisa wesiginali wemishini yevidiyo, ukusakazwa kwethelevishini kanye nohlelo lwethelevishini lekhebula nokwenza ukuncipha kwesiginali yokudlulisa.
2. Ukuhlanekezela okuphansi: I-attenuator inganciphisa amandla wesiginali ngaphandle kokwethula ukuhlukaniswa okwengeziwe noma ukuphazamiseka kwesiginali.
I-3. Ukwethenjwa okuphezulu: Ngenxa yokuthi ama-actenuators ikakhulukazi anezinto ezingenangqondo futhi azinazo izingxenye ezinyakazayo, zithembekile kakhulu futhi azidingi ukulungiswa noma ukushintshwa.

Ama-actenuators angama-75 ajwayele ukusetshenziswa ezinhlelweni ezilandelayo:

1. Kumanethiwekhi wethelevishini le-Cable kanye namanethiwekhi wethelevishini e-Digital Television, kusetshenziselwa ukulawula amandla esiginali futhi kuncishiswe ukuboniswa kwesiginali nokulahleka.
2. Ngesikhathi sokukhiqizwa kanye nokudluliselwa kwamavidiyo aphezulu namavidiyo aphezulu okuchazwa okuphezulu, alawule amandla wesiginali futhi alondoloze ikhwalithi yokuguqulwa.
I-3. Izinhlelo zokuhambisa zesakaza nethelevishini, imishini eguqula amandla esiginali ukufanisa ukucubungula okuthile okusatshalaliswa futhi andise uhla lwesiginali.
4. Ku-antevision antennas, esetshenziselwa ukulinganisa amandla wesiginali phakathi kwama-amplifiers kanye nezimpondo.

QoqaIMISEBENZI EBALULEKILE KANYE NAMANDLA OKUGCWELEKILE KAKHULU KANYE NAMANDLA OKUPHELELE KAKHULU 75 OHMS ACOTENOOR ATHOLA I-Frequency Range DC ~ 3GHZ, ingafaniswa ne-BNC, F-TYPE, kanye nezixhumi zohlobo lwe-N. I-attenuation ikakhulukazi isukela ku-1 kuye ku-40DB. Ama-actonuators anokunemba okuphezulu namandla aphezulu, ikhwalithi ethembekile, imikhiqizo eminingi yi-rohs ethobela, ingahlangabezana nezidingo ezihlukile zamakhasimende.
