Menene gwajin RF

1. Menene gwajin RF

Mitar rediyo, wanda aka fi sani da RF.Gwajin mitar rediyo shine halin yanzu na mitar rediyo, wanda shine gajarta don musanya manyan igiyoyin lantarki na yanzu.Yana wakiltar mitar lantarki wanda zai iya haskaka sararin samaniya, tare da kewayon mitar daga 300KHz zuwa 110GHz.Mitar rediyo, wanda aka gajarta azaman RF, gajeriyar hannu ce don musanya manyan igiyoyin lantarki na yanzu.Yawan canjin kasa da sau 1000 a cikin dakika ana kiransa low-frequency current, kuma yawan canjin fiye da sau 10000 ana kiransa high-frequency current.Mitar rediyo shine irin wannan nau'in babban mitar halin yanzu.

Mitar watsawa tana ko'ina, ko WI-FI ce, Bluetooth, GPS, NFC (matsakaicin sadarwa mara waya), da sauransu, duk suna buƙatar watsa mitar.A halin yanzu, ana amfani da fasahar mitar rediyo sosai a fagen sadarwa mara waya, kamar RFID, sadarwar tashar tashar, sadarwar tauraron dan adam, da sauransu.

A cikin tsarin sadarwar mara waya, RF na gaba-gaba na ƙara ƙarfin wutar lantarki abu ne mai mahimmanci.Babban aikinsa shine ƙara ƙaramar sigina da samun takamaiman ƙarfin fitarwa na RF.Sigina mara igiyar waya suna samun raguwa sosai a cikin iska.Domin kiyaye ingantaccen ingancin sabis na sadarwa, ya zama dole a haɓaka siginar da aka daidaita zuwa isasshe babban girman kuma watsa shi daga eriya.Ita ce jigon tsarin sadarwar mara waya da kuma tantance ingancin tsarin sadarwa.

2. RF gwajin hanyoyin

1. Haɗa mai rarraba wutar lantarki ta amfani da kebul na RF bisa ga zanen da ke sama, kuma auna asarar 5515C zuwa EUT da EUT zuwa spectrometer ta amfani da tushen sigina da spectrograph, sannan rikodin ƙimar asarar.
2. Bayan auna asarar, haɗa EUT, E5515C, da spectrograph zuwa mai rarraba wutar lantarki bisa ga zane, kuma haɗa ƙarshen mai rarraba wutar lantarki tare da haɓaka mai girma zuwa spectrograph.
3. Daidaita ramuwa don lambar tashar da asarar hanya akan E5515C, sannan saita E5515C bisa ga sigogi a cikin tebur mai zuwa.
4. Ƙaddamar da haɗin kira tsakanin EUT da E5515C, sa'an nan kuma daidaita ma'auni na E5515C zuwa yanayin sarrafa wutar lantarki na duk ragi don bawa EUT damar fitarwa a iyakar iko.
5. Saita ramuwa don asarar hanya akan spectrograph, sa'an nan kuma gwada kuskuren da aka gudanar bisa ga mitar mitar a cikin tebur mai zuwa.Ƙarfin kololuwar kowane yanki na bakan da aka auna dole ne ya zama ƙasa da iyakar da aka ƙayyade a cikin ma'aunin tebur mai zuwa, kuma ya kamata a yi rikodin bayanan da aka auna.
6. Sa'an nan kuma sake saita sigogi na E5515C bisa ga tebur mai zuwa.
7. Ƙirƙiri sabon haɗin kira tsakanin EUT da E5515C, kuma saita sigogin E5515C zuwa wasu hanyoyin sarrafa wutar lantarki na 0 da 1.
8. Bisa ga tebur mai zuwa, sake saita spectrograph kuma gwada kuskuren da aka gudanar bisa ga rarrabuwar mita.Ƙarfin kololuwar kowane ɓangaren bakan da aka auna dole ne ya zama ƙasa da iyakar da aka kayyade a ma'aunin tebur mai zuwa, kuma bayanan da aka auna yakamata a yi rikodin.

3. Kayan aikin da ake buƙata don gwajin RF

1. Don na'urorin RF da ba a kunshe ba, ana amfani da tashar bincike don daidaitawa, kuma ana amfani da kayan aiki masu dacewa kamar spectrographs, vector network analyzers, mita wuta, janareta na sigina, oscilloscopes, da sauransu.
2. Za a iya gwada abubuwan da aka haɗa kai tsaye tare da kayan aiki, kuma abokan masana'antu suna maraba don sadarwa.
