Kodi RF test ndi chiyani

1. Kodi kuyesa kwa RF ndi chiyani

Radio Frequency, yomwe nthawi zambiri imafupikitsidwa ngati RF.Kuyesa kwa ma radio frequency ndi ma radio frequency current, chomwe ndi chidule cha mafunde a electromagnetic osintha pafupipafupi.Imayimira ma frequency a electromagnetic omwe amatha kuwulukira mumlengalenga, ndi ma frequency osiyanasiyana kuchokera ku 300KHz mpaka 110GHz.Ma frequency a wailesi, ofupikitsidwa ngati RF, ndi chidule cha mafunde amagetsi amagetsi amakono.Kuchuluka kwa kusintha kosachepera 1000 pa sekondi kumatchedwa kutsika kwapang'onopang'ono, ndipo kusinthasintha kwapafupipafupi kuposa nthawi 10000 kumatchedwa high-frequency current.Maulendo a wailesi ndi mtundu uwu wa ma frequency apamwamba.

Kutumiza pafupipafupi kuli ponseponse, kaya ndi WI-FI, Bluetooth, GPS, NFC (kulumikizana kozungulira kopanda zingwe), ndi zina zotere, zonse zimafunikira kufalitsa pafupipafupi.Masiku ano, ukadaulo wamagetsi wamagetsi umagwiritsidwa ntchito kwambiri pankhani yolumikizirana opanda zingwe, monga RFID, kulumikizana koyambira, kulumikizana kwa satellite, ndi zina zambiri.

M'makina olumikizirana opanda zingwe, ma amplifiers akutsogolo a RF ndi gawo lofunikira.Ntchito yake yayikulu ndikukulitsa ma siginecha opanda mphamvu ndikupeza mphamvu zina za RF.Mazikoni opanda zingwe amatsika kwambiri mumlengalenga.Kuti mukhalebe wokhazikika wautumiki woyankhulirana, ndikofunikira kukulitsa siginecha yosinthidwa kukhala yayikulu mokwanira ndikuitumiza kuchokera ku mlongoti.Ndiwo maziko a machitidwe oyankhulana opanda zingwe ndipo amatsimikizira ubwino wa njira yolumikizirana.

2, njira zoyesera za RF

1. Lumikizani chogawa mphamvu pogwiritsa ntchito chingwe cha RF molingana ndi chithunzi pamwambapa, ndikuyesa kutayika kwa 5515C ku EUT ndi EUT ku spectrometer pogwiritsa ntchito gwero la chizindikiro ndi spectrograph, ndiyeno lembani zotayika.
2. Mutatha kuyeza kutayika, gwirizanitsani EUT, E5515C, ndi spectrograph ku chogawa mphamvu molingana ndi chithunzicho, ndikugwirizanitsa mapeto a chogawanitsa mphamvu ndi kuchepetsedwa kwakukulu kwa spectrograph.
3. Sinthani malipiro a nambala ya tchanelo ndi kutaya njira pa E5515C, ndiyeno ikani E5515C molingana ndi magawo omwe ali patebulo lotsatirali.
4. Khazikitsani kulumikizana kwa mafoni pakati pa EUT ndi E5515C, ndiyeno sinthani magawo a E5515C kuti azitha kuwongolera mphamvu pama bits onse kuti EUT itulutse mphamvu zambiri.
5. Khazikitsani chipukuta misozi cha kutayika kwa njira pa spectrograph, ndiyeno yesani kusokera kochitidwa molingana ndi magawo pafupipafupi patebulo lotsatirali.Mphamvu yapamwamba ya gawo lililonse la sipekitiramu yoyezedwa iyenera kukhala yotsika kuposa malire omwe afotokozedwa patebulo lotsatirali, ndipo deta yoyezedwa iyenera kulembedwa.
6. Kenako sinthaninso magawo a E5515C molingana ndi tebulo ili.
7. Khazikitsani kulumikizana kwatsopano kwa mafoni pakati pa EUT ndi E5515C, ndikukhazikitsa magawo a E5515C kuti asinthe njira zowongolera mphamvu za 0 ndi 1.
8. Malinga ndi tebulo ili m'munsiyi, yambitsaninso spectrograph ndikuyesa zomwe zasochera molingana ndi magawo afupipafupi.Mphamvu yapamwamba ya gawo lililonse la sipekitiramu yoyezedwa iyenera kukhala yotsika kuposa malire omwe afotokozedwa patebulo ili, ndipo deta yoyezedwa iyenera kulembedwa.

3, Zida zofunika pakuyesa kwa RF

1. Pazida za RF zosapakidwa, malo opangira kafukufuku amagwiritsidwa ntchito pofananiza, ndipo zida zofunikira monga ma spectrograph, ma vector network analyzer, mita yamagetsi, majenereta azizindikiro, ma oscilloscopes, ndi zina zambiri zimagwiritsidwa ntchito poyesa magawo ofanana.
2. Zigawo zophatikizidwa zimatha kuyesedwa mwachindunji ndi zida, ndipo abwenzi amakampani amaloledwa kulankhulana.
