Chidziwitso cha cholumikizira cha BNC

BNC cholumikizira ndi cholumikizira cha chingwe coaxial, chomwe chimagwiritsidwa ntchito kwambiri pamakina olankhulirana.

Kapangidwe ka cholumikizira cha BNC

Zolumikizira za BNC zikuphatikizapo:

Bnc-t mutu kulumikiza khadi maukonde kompyuta ndi chingwe mu maukonde;

BNC ndowa cholumikizira polumikiza zingwe ziwiri mu chingwe yaitali;

BNC chingwe cholumikizira, ntchito kuwotcherera kapena screwing pa mapeto a chingwe;

BNC terminator imagwiritsidwa ntchito poletsa kusokoneza komwe kumachitika chifukwa cha siginecha yomwe imawonetsedwa pambuyo pakutha kwa chingwe.Terminator ndi cholumikizira chapadera chokhala ndi kukana kosankhidwa bwino kuti kufanane ndi mawonekedwe a chingwe cha netiweki.Terminal iliyonse iyenera kukhazikitsidwa.

Zofunikira zazikulu za cholumikizira cha BNC

1, chikhalidwe impedance

Kulephera kwa mawonekedwe a BNC cholumikizira ndi choposa 50 ω ndi 75 ω.Mitundu yambiri ya zolumikizira za BNC imapezeka mumitundu yonse ya 50 ω ndi 75 ω.

Nthawi zambiri, zolumikizira za 50 ω BNC zimagwiritsidwa ntchito pafupipafupi, zinthu zogwira ntchito kwambiri;75 ω BNC zolumikizira zimagwiritsidwa ntchito pazinthu zomwe zimakhala ndi ma frequency otsika, makamaka pansi pa 4GHz, makamaka pamakanema apakompyuta ogula.Ogwiritsa ntchito asankhe cholumikizira cha BNC chomwe chikugwirizana ndi kulephera kwawo malinga ndi zomwe apanga.

2, pafupipafupi,

TYPE iliyonse ya cholumikizira cha BNC imakhala ndi ma frequency angapo, ndipo ogwiritsa ntchito ayenera kudziwa kuchuluka kwa ntchito yawo kuti asankhe cholumikizira.Kusankha zolumikizira zokhala ndi ma frequency ocheperako kuposa momwe zimafunikira kumakhudza magwiridwe antchito amagetsi a makina onse;Kapena sankhani zolumikizira zokwera mtengo kwambiri zomwe zimapangitsa kuti ziwonongeke.

3 chitsanzo, VSWR

VSWR ndi chimodzi mwazizindikiro zofunika kwambiri za cholumikizira cha BNC.Ndi muyeso woyezera kuchuluka kwa chizindikiro chomwe chabwezedwa kuchokera ku cholumikizira.Ndi gawo la vector kuphatikiza matalikidwe ndi magawo agawo.VSWR ya cholumikizira chomwecho ndi yosiyana pama frequency osiyanasiyana.Nthawi zambiri, kuchuluka kwa kuchuluka kwa kugwiritsidwa ntchito kumakwera, VSWR imakwera.

Ubwino wa cholumikizira cha BNC:

1, BNC cholumikizira pamwamba pa chinthucho, zokutira ndi zabwino komanso zowala, chiyero chamkuwa chimakhala chowala, zinthu zina zimawala kunja, koma ndichitsulo.

2, maginito adsorption mayeso, kawirikawiri bayonet masika ndi mchira kasupe ndi chitsulo;Waya clamp, pini ndi casing amapangidwa ndi mkuwa, ndipo mbali zina zimapangidwa ndi aloyi ya zinc

3. Palani zokutira pamwamba kuti muwone zakuthupi: palani zokutira pamwamba pa tsamba ndi zida zina zakuthwa kuti muwone zakuthupi mwachilengedwe, ndikuyerekeza mwachidziwitso zinthu zopangidwa mwa kukanda waya kopanira, pini ndi malaya achitetezo.

4. Kuphatikiza pa njira zomwe zili pamwambazi, mukhoza kukonzekera mutu waukazi wabwino kuti muyese.
