Isenzo Se-Coaxial Cable

Isikhele sesiqalo sijongwa ngemibuzo. Isikhelo esedlange kwiseqalo sesikhele setshonalwa ukuthi usebenzise amasixhobo. Umeshi wamatala wamanye amarha wasekelisiwe ngemibuzo: yinto elinye iyindlela lemkhaba elikhoyo lokusebenza njengamasixhobo okukhawuleka umdlalo wesithathu lesisignalo; yinto elinye iyindlela lemkhaba elikhoyo lokugcina ukusuka komphendulo weelektri kwi-signal. Isikhelo esedlange kunye nokushesha kumemezi khona phakathi kwesilayithi semipropileni efundekileyo, okuyenzelisa iimboniso zokuthumela ngekhabelo lomthombo.

Amacabhele amaxhoxho asebenzeka ngokupheleleyo kwiqhelenkosi lomphendulo wesithathu noma yeeRF. Impendulo yesixhumanisi sifunekuxhoxwa ngokushesha ku-75_, okuningi ukuthi lokhu kusebenzisa kukwahlula impendulo yesithathu (ngasinye, impendulo ye-50_ yakusebenziswayo kusenqanawe yesithathu). Isicabhele somaxhoxho semphendulo esisophu sohlukileyo sokuba kuhlukaniswa ngokubanzi kunye nokulandelana neentsingiselo zomphendulo zamashoni namaphrofayela. Ukudibanisa, uphumla kwesixhumanisi sesikhundla noma umsuka wosixhumanisi wesicabhele sibonisa indlela yokugcina kwiqhelenkosi lemfazwe weziqhobo zomphendulo.

Ngakwesiqinisekiso, kufanele kube kuhloniphe ithetho lethu lokusebenza kwezindlela ezidingekayo kwisebenti lesicabhele, isebenti sishesha siphumelele kakhulu. Ngokugcineneyo, kufuneka kube iindlela eziqondisiwe ngamabili ngokuyenza ukuthi usheshwe ukuhamba kweesiqhovini.

Isimo Sokuqasha:

Amacabhele amaxhoxho akusebenzeka phakathi komphendulo.Wahamba kuhluke isihloko esisetyenziswa ngumntu omsebenzi ngalokhu ukufaka umbhali wesithathu.Wahamba kuhluke ukusetshenziswa ngokungafani na:

(1) umntu omncane

Cuta ilayisini kunye nezandla ezi-BNC kwiindle ekwesiqheleni sokuqala nesiqaleli somlayo, phakathi hlela kwezandla ezimbini zesi-T connector.

(2) umntu omkhulu

Ilayisini elikhulu liyibhukisiwe ngokwengeziyo yenqanawe yokugcwalisa i-TAP, okufuneka usebenze impinzi yaseTAP ukususwa isiqephu sasendaweni sokulayisini kunye nokuhambisana ngokushesha nge-conductor. Izindlu zihlola zihlola kumgca wokuqala kunye nokuphela kwesilayisini sokuthola ukungabuyelele amaxhobo.
