RF test yog dab tsi

1, RF xeem yog dab tsi

Xov tooj cua zaus, feem ntau abbreviated li RF.Xov tooj cua zaus kuaj yog xov tooj cua zaus tam sim no, uas yog ib tug luv luv rau high-frequency alternating tam sim no electromagnetic tsis.Nws sawv cev rau cov zaus electromagnetic uas tuaj yeem tawg mus rau hauv qhov chaw, nrog ntau zaus ntawm 300KHz txog 110GHz.Xov tooj cua zaus, abbreviated li RF, yog ib tug shorthand rau high-frequency alternating tam sim no electromagnetic tsis.Qhov zaus ntawm kev hloov tsawg dua 1000 zaug ib ob yog hu ua low-frequency tam sim no, thiab qhov zaus ntawm kev hloov ntau tshaj 10000 zaug yog hu ua high-frequency tam sim no.Xov tooj cua zaus yog hom high-frequency tam sim no.

Kev sib kis ntau zaus yog ubiquitous, txawm nws yog WI-FI, Bluetooth, GPS, NFC (kaw sib txuas lus wireless), thiab lwm yam., txhua yam yuav tsum muaj kev sib kis ntau zaus.Niaj hnub no, xov tooj cua zaus siv tshuab tau dav siv hauv kev sib txuas lus wireless, xws li RFID, kev sib txuas lus hauv chaw nres tsheb, kev sib txuas lus satellite, thiab lwm yam.

Hauv kev sib txuas lus wireless, RF pem hauv ntej-kawg fais fab amplifiers yog qhov tseem ceeb heev.Nws lub luag haujlwm tseem ceeb yog txhawm rau ua kom lub zog qis qis thiab tau txais qee lub zog RF tso zis.Wireless signals muaj kev cuam tshuam tseem ceeb hauv huab cua.Txhawm rau kom muaj kev sib txuas lus ruaj khov kev pab cuam zoo, nws yog ib qho tsim nyog yuav tsum tau ua kom lub teeb liab hloov mus rau qhov loj txaus thiab xa tawm ntawm lub kav hlau txais xov.Nws yog lub hauv paus ntawm kev sib txuas lus wireless thiab txiav txim siab qhov zoo ntawm kev sib txuas lus.

2, RF xeem txoj kev

1. Txuas lub hwj chim faib siv lub RF cable raws li daim duab saum toj no, thiab ntsuas qhov poob ntawm 5515C rau EUT thiab EUT rau lub spectrometer siv lub teeb liab qhov chaw thiab spectrograph, thiab tom qab ntawd sau cov txiaj ntsig poob.
2. Tom qab ntsuas qhov poob, txuas lub EUT, E5515C, thiab spectrograph mus rau lub hwj chim divider raws li daim duab, thiab txuas qhov kawg ntawm lub hwj chim divider nrog ntau dua attenuation rau lub spectrograph.
3. Kho cov nyiaj them rau tus lej channel thiab kev poob ntawm E5515C, thiab tom qab ntawd teeb tsa E5515C raws li qhov tsis muaj nyob hauv cov lus hauv qab no.
4. Tsim kom muaj kev sib txuas ntawm EUT thiab E5515C, thiab tom qab ntawd kho qhov tsis sib xws E5515C rau lub zog tswj hom ntawm tag nrho cov khoom kom ua rau EUT tso tawm ntawm lub zog siab tshaj plaws.
5. Teem cov nyiaj them rau txoj kev poob ntawm lub spectrograph, thiab tom qab ntawd sim cov kev ua yuam kev raws li qhov zaus segmentation hauv cov lus hauv qab no.Lub zog siab tshaj plaws ntawm txhua ntu ntawm cov ntsuas ntsuas yuav tsum qis dua qhov txwv tau teev tseg hauv cov qauv hauv qab no, thiab cov ntaub ntawv ntsuas yuav tsum tau sau tseg.
6. Tom qab ntawd rov pib dua qhov tsis muaj E5515C raws li cov lus hauv qab no.
7. Tsim kom muaj kev sib txuas hu xov tooj tshiab ntawm EUT thiab E5515C, thiab teeb tsa E5515C tsis txwv rau lwm hom kev tswj fais fab ntawm 0 thiab 1.
8. Raws li cov lus hauv qab no, rov pib dua lub spectrograph thiab kuaj qhov ua yuam kev raws li qhov zaus segmentation.Lub zog siab tshaj plaws ntawm txhua ntu spectrum ntsuas yuav tsum qis dua qhov txwv tau teev tseg hauv cov qauv hauv qab no, thiab cov ntaub ntawv ntsuas yuav tsum tau sau tseg.

3, Cov cuab yeej xav tau rau kev kuaj RF

1. Rau cov khoom siv RF tsis ntim khoom, lub chaw sojntsuam yog siv rau kev sib txuam, thiab cov cuab yeej cuam tshuam xws li spectrographs, vector network analyzers, fais fab ntsuas, teeb liab generators, oscilloscopes, thiab lwm yam.
2. Cov khoom ntim tuaj yeem raug kuaj ncaj qha nrog cov cuab yeej, thiab cov phooj ywg kev lag luam zoo siab tos txais kev sib txuas lus.
