Cov khoom siv RF calibration yog ib qho cuab yeej tseem ceeb los xyuas kom meej tias vector network analyzer (VNA) thiab lwm yam khoom siv RF muab kev ntsuas raug rau lub dav hlau ntawm cov khoom siv. Vim muaj qhov nce hauv theem thiab impedance hloov pauv hauv kev sib txuas ntawm cov cuab yeej ntsuas RF, kev ntsuas ua los ntawm VNA yam tsis muaj kev ntsuas yuav suav nrog S-tsis txwv thiab lub sij hawm-sau tus yam ntxwv ntawm kev sib txuas kev sib txuas. Cov khoom siv calibration yog siv los muab lub dav hlau siv los ntawm kev sib txuas ntawm DUT. Nyob rau hauv txoj kev no, RF kuaj cov cuab yeej (feem ntau yog VNA) tuaj yeem ua haujlwm ua haujlwm nyuaj yam tsis tas yuav tsum tau ua cov ntaub ntawv ntxiv.

Lub luv luv-circuit Cheebtsam ntawm cov khoom siv calibration yog siv los "luv-circuit" lub zog generated thiab emitted los ntawm VNA, thaum lub qhib-circuit tivthaiv yog formally kawg ntawm ib tug unterminated kis kab mob uas tsis pub coupling thiab hluav taws xob los ntawm sab nraud. ib puag ncig.
Kev thauj khoom ntawm cov khoom siv calibration yog siv los ua kom haum cov kab sib kis impedance thiab chaw nres nkoj impedance ntawm VNA thiab cov khoom siv kuaj.
Lub adapter ncaj nraim yog ib qho yooj yim adapter uas txuas ob qhov chaw nres nkoj ntawm cov khoom siv calibration, thiab tsis pom vim nws lub hom phiaj tsim kom nyob ze rau cov kab sib kis zoo tshaj plaws. Cov khoom siv calibration suav nrog ntau tus qauv coaxial txuas ntawm qhov sib txawv, nrog rau feem ntau yog N-hom connector.
Vim muaj ntau yam khoom siv kuaj thiab coaxial cables, precision adapter kits yog ib qho tseem ceeb heev accessory rau calibration kits. Rau cov adapters zoo li no, lawv yuav tsum muaj cov khoom zoo.
QualwaveInc. muab Cov Khoom Siv Calibration nrog ntau hom kom tau raws li cov neeg siv khoom xav tau.
