Ulwazi lwesihlanganisi se-BNC

Isidibanisi se-BNC sisidibanisi sentambo ye-coaxial, esetyenziswa ngokubanzi kwiinkqubo zonxibelelwano.

Ulwakhiwo lwesiqhagamshelo se-BNC

Izihlanganisi ze-BNC ziquka:

Intloko ye-Bnc-t yokudibanisa ikhadi lenethiwekhi yekhompyutheni kunye nentambo kwinethiwekhi;

Isidibanisi sebhakethi se-BNC sokudibanisa iintambo ezimbini kwintambo ende;

Isixhumi sentambo ye-BNC, esetyenziselwa i-welding okanye i-screwing ekupheleni kwentambo;

I-terminator ye-BNC isetyenziselwa ukuthintela ukuphazamiseka okubangelwa ngumqondiso obonakaliswe ngasemva emva kokufikelela kwikhefu lentambo.I-terminator isinxibelelanisi esikhethekileyo kunye nokuchasana okukhethiweyo ngokucokisekileyo ukuhambelana neempawu zentambo yenethiwekhi.Itheminali nganye kufuneka isekelwe phantsi.

Iimpawu eziphambili ze-BNC isihlanganisi

I-1, i-impedance yeempawu

I-impedance yeempawu ze-BNC isinxibelelanisi ingaphezulu kwe-50 ω kunye ne-75 ω.Uluhlu oluninzi lwezixhumi ze-BNC zifumaneka kuzo zombini i-50 ω kunye ne-75 ω iinkcukacha.

Ngokubanzi, i-50 ω BNC izixhumi zisetyenziselwa ukuphindaphinda okuphezulu, iimveliso eziphezulu zokusebenza;75 ω Izihlanganisi ze-BNC zisetyenziselwa iimveliso ezinezandi ezisezantsi, ubukhulu becala ngaphantsi kwe-4GHz, ngakumbi kubathengi bevidiyo ye-elektroniki.Abasebenzisi kufuneka bakhethe isidibanisi se-BNC esihambelana nokuphazamiseka kwabo ngokwemveliso yabo.

2, amaxesha amaninzi,

UHLOBO ngalunye lwe-BNC isinxibelelanisi sinoluhlu lwamaza, kwaye abasebenzisi kufuneka bazi imveliso yabo yokusebenza rhoqo ukuze bakhethe isinxibelelanisi.Ukukhetha izihlanganisi ezine-frequency ephantsi yokusebenza kunokuba zifunwa kuya kuchaphazela ukusebenza kombane kumatshini wonke;Okanye khetha iziqhagamshelo ezixabisa kakhulu ezichanekileyo ezikhokelela kwinkcitho.

ipateni ye-3, i-VSWR

I-VSWR yenye yezona zibonakaliso zentsebenzo ezibalulekileyo ze-BNC isinxibelelanisi.Ngumgangatho womlinganiselo wobungakanani bomqondiso obuyiswe kwikhonkco.Yiyunithi ye-vector equka i-amplitude kunye nesigaba sesigaba.I-VSWR yesiqhagamshelanisi esifanayo yahlukile kwiifrikhwensi ezahlukeneyo.Ngokubanzi, ukuphakama kokusetyenziswa rhoqo, kokukhona i-VSWR ephezulu.

Umgangatho wesihlanganisi se-BNC:

I-1, isinxibelelanisi se-BNC kumphezulu wemveliso, i-coating ilungile kwaye iqaqambile, ukuphakama kokucoceka kobhedu kuqaqambile, ezinye iimveliso ziqaqambile ngaphandle, kodwa ziyintsimbi.

2, uvavanyo lwe-adsorption yemagnethi, ngokubanzi kuphela intwasahlobo ye-bayonet kunye nentwasahlobo yomsila ngezinto zentsimbi;I-wire clamp, i-pin kunye ne-casing yenziwe ngobhedu, kwaye ezinye iindawo zenziwe nge-alloy zinc

3. Gcoba i-coating ye-surface ukuze ubone izinto: krwela i-coating ebusweni be-blade kunye nezinye izixhobo ezibukhali ukuze ubone izinto eziphathekayo, kwaye uthelekise ngokufanelekileyo imveliso yemveliso ngokukhuhla i-clip yocingo, i-pin kunye ne-shield sleeve sleeve.

4. Ukongeza kwezi ndlela zingasentla, unokuphinda ulungiselele intloko yowesifazane osemgangathweni ukuba uzame.
