75 ohms Attenuator 75ω Yakosowe 75 Ohms Yakosowe
A ohms Attenus Attenu ni ubwoko bwa Antukutor yitiriwe ingaruka za Omms 75.
Nibintu bisate byakoreshwaga mu kugenzura imbaraga z'Umuzunguruko, Afata 75ω Antunu irinda Yorotanogarafizi nyinshi no kugoreka ibimenyetso, kandi bikabuza gutsindwa kwatewe no kurenza urugero.
75ω Apengeator zihamye Ibiranga birimo:
1. Impedance matching: The 75 Ohms fixed attenuator impedance matches the characteristic impedance of the signal transmission line of the video equipment, television broadcast and cable television system, thus reducing the reflection and loss of the transmission signal.
2. Kugoreka hasi: Afashanya irashobora kugabanya imbaraga z'ikimenyetso utahuye n'inyongera yo kugoreka cyangwa kwivanga.
3. Kwizerwa kwizerwa: Bitewe nuko abafatanyabikorwa cyane cyane bagize ibice byingenzi kandi nta bice byimuka, bizewe cyane kandi ntibisaba kubungabunga cyangwa gusimburwa.
75 Ohms Attenuator isanzwe ikoreshwa mubisabwa bikurikira:
1. Mu miyoboro ya tereviziyo hamwe n'imiyoboro ya tereviziyo, ikoreshwa mu kugenzura ibimenyetso no kugabanya ibimenyetso n'ibihombo.
2. Mugihe cyo gukora no kwanduza imyanzuro yo hejuru hamwe na videwo-zisobanura-gusobanura, kugenzura imbaraga z'ikimenyetso kandi ukomeze ubuziranenge.
3. Mu gitabo cyatangajwe na televiziyo yerekana ibimenyetso, ibikoresho bihindura imbaraga zo guhuza ibicuruzwa byatanzwe no kwagura ibimenyetso.
4. Muri tereviziyo, ikoreshwa mu kuringaniza imbaraga zimenyetso hagati ya Amplifiers na antenna.
UmwandaIbikoresho bitandukanye cyane hamwe nubusambanyi buhanitse 75 Ohms Attenuatos Cover Intera DC ~ 3GHZ, irashobora guhuzwa na BNC, ihujwe na BNC, Ubwoko bwa FC, ubwoko bwa F-Ubwoko bwa F Gutera imbere cyane cyane kuva 1 kugeza 40DB. Afashanya hamwe nububasha buke kandi buhanitse, ubuziranenge bwizewe, ibicuruzwa byinshi ni Rohs yubahiriza, birashobora kuzuza ibikenewe bitandukanye byabakiriya.
