- Ukuchaneka okuphezulu
Ikhithi yokulinganisa iRF sisixhobo esiphambili sokuqinisekisa ukuba i-vector network analyzer (VNA) kunye nezinye izixhobo zeRF zibonelela ngomlinganiselo ochanekileyo wenqwelomoya yovavanyo lwesixhobo. Ngenxa yokonyuka okungokwemvelo kwisigaba kunye notshintsho lwe-impedance ekudibaneni kwezixhobo zokuvavanya i-RF, imilinganiselo eyenziwa nge-VNA ngaphandle kokulungelelaniswa iya kubandakanya i-S-parameters kunye neempawu ze-domain yexesha lenkqubo yokuvavanya ukudibanisa. Ikhithi yolungelelwaniso isetyenziselwa ukubonelela ngenqwelo-moya yokukhangela eqala kuqhagamshelo lwe-DUT. Ngale ndlela, izixhobo zovavanyo lweRF (ikakhulukazi i-VNA) zinokwenza ngokuzenzekelayo imisebenzi edibeneyo yokubethelela ngaphandle kwesidingo sokulungiswa kwedatha eyongezelelweyo.

Icandelo le-short-circuit yekiti yokulinganisa isetyenziselwa "i-short-circuit" amandla enziwe kwaye akhutshwe yi-VNA, ngelixa icandelo le-open-circuit liphelile ngokusesikweni umgca wothumelo ongapheliyo ongavumeli ukudibanisa kunye nemitha evela ngaphandle. okusingqongileyo.
Umthwalo wekiti yokulinganisa isetyenziselwa ukufanisa i-impedance ye-transmission line kunye ne-port impedance ye-VNA kunye nezixhobo ezivavanyiweyo.
I-adapter echanekileyo yi-adapter elula edibanisa izibuko ezimbini zekiti yokulinganisa, kwaye ayibonakali ngenxa yenjongo yayo yokuyila ukuba ibe kufuphi nomgca wokuhambisa ofanelekileyo ngokusemandleni. Ikhithi yokulinganisa ibandakanya izihlanganisi ezahlukeneyo ezisemgangathweni ze-coaxial zobukhulu obahlukeneyo, kunye neyona nto ixhaphakileyo sisidibanisi sohlobo lwe-N.
Ngenxa yoluhlu olubanzi lwezixhobo ezivavanyiweyo kunye neentambo ze-coaxial, iikhithi ze-adapter ezichanekileyo ziyi-accessory ebaluleke kakhulu kwiikiti zokulinganisa. Kwiiadaptha ezinjalo, kufuneka zibe nomgangatho ophezulu.
QualwaveI-Inc. ibonelela ngeeKits zoCalibration ngeentlobo ezahlukeneyo ukuhlangabezana neemfuno zabathengi.
