Kuyini ukuhlolwa kwe-RF

1. Kuyini ukuhlolwa kwe-RF

I-Radio Frequency, evame ukufushaniswa njenge-RF.Ukuhlolwa kwefrikhwensi yomsakazo i-radio frequency current, okuyisifinyezo samaza kagesi ashintshashintshayo amanje.Imele ifrikhwensi kazibuthe kagesi engaphumela emkhathini, ngebanga lefrikhwensi ukusuka ku-300KHz ukuya ku-110GHz.Ifrikhwensi yomsakazo, efushanisiwe njenge-RF, iyisifinyezo samaza amanje kagesi ashintshashintshayo.Imvamisa yokushintsha izikhathi ezingaphansi kuka-1000 ngomzuzwana ibizwa ngokuthi i-low-frequency current, futhi imvamisa yoshintsho izikhathi ezingaphezu kuka-10000 ibizwa ngokuthi i-high-frequency current.Ifrikhwensi yerediyo ilolu hlobo lwamanje lwefrikhwensi ephezulu.

Ukudluliswa kwemvamisa kutholakala yonke indawo, kungakhathaliseki ukuthi i-WI-FI, i-Bluetooth, i-GPS, i-NFC (ukuxhumana okungenazintambo okuseduze), njll., konke kudinga ukudluliswa kwamafrikhwensi.Namuhla, ubuchwepheshe befrikhwensi yomsakazo busetshenziswa kabanzi emkhakheni wokuxhumana okungenantambo, njenge-RFID, ukuxhumana kwesiteshi sesisekelo, ukuxhumana ngesathelayithi, njll.

Ezinhlelweni zokuxhumana ezingenantambo, izikhulisamandla ze-RF front-end ziyingxenye ebalulekile.Umsebenzi wayo oyinhloko ukukhulisa amasiginali wamandla aphansi nokuthola amandla athile okukhipha i-RF.Amasignali angenantambo athola ukuncipha okukhulu emoyeni.Ukuze kugcinwe ikhwalithi yesevisi yokuxhumana ezinzile, kuyadingeka ukukhulisa isignali eshintshiwe ibe usayizi omkhulu ngokwanele futhi uyidlulise isuka othini.Iwumongo wezinhlelo zokuxhumana ezingenazintambo futhi inquma ikhwalithi yohlelo lokuxhumana.

2, Izindlela zokuhlola i-RF

1. Xhuma isihlukanisi samandla usebenzisa intambo ye-RF ngokuvumelana nomdwebo ongenhla, futhi ulinganise ukulahlekelwa kwe-5515C kuya ku-EUT ne-EUT ku-spectrometer usebenzisa umthombo wesignali ne-spectrograph, bese urekhoda amanani okulahlekelwa.
2. Ngemva kokulinganisa ukulahlekelwa, xhuma i-EUT, i-E5515C, ne-spectrograph kusihlukanisi samandla ngokomdwebo, bese uxhuma isiphetho sesihlukanisi samandla ngokuncishiswa okukhulu ku-spectrograph.
3. Lungisa isinxephezelo senombolo yesiteshi nokulahleka kwendlela ku-E5515C, bese usetha u-E5515C ngokuya ngemingcele kuthebula elilandelayo.
4. Sungula uxhumano lwekholi phakathi kwe-EUT ne-E5515C, bese ulungisa amapharamitha e-E5515C kumodi yokulawula amandla yazo zonke izibhithi eziphezulu ukuze i-EUT ikwazi ukukhipha ngamandla amakhulu.
5. Setha isinxephezelo sokulahleka kwendlela ku-spectrograph, bese uhlola ukuduka okwenziwe ngokwesegimenti yefrikhwensi kuthebula elilandelayo.Amandla aphezulu engxenye ngayinye ye-spectrum elinganisiwe kufanele abe ngaphansi komkhawulo oshiwo ezingeni elilandelayo lethebula, futhi idatha elinganisiwe kufanele irekhodwe.
6. Bese usetha kabusha amapharamitha we-E5515C ngokwethebula elilandelayo.
7. Sungula uxhumano olusha lwekholi phakathi kwe-EUT ne-E5515C, futhi usethe amapharamitha e-E5515C ukuze ashintshe amamodi okulawula amandla ka-0 kanye no-1.
8. Ngokusho kwethebula elilandelayo, setha kabusha i-spectrograph futhi uhlole i-stray eyenziwe ngokuya ngesegimenti yamafrikhwensi.Amandla aphezulu engxenye ngayinye ye-spectrum elinganiselwe kufanele abe ngaphansi komkhawulo oshiwo ezingeni elilandelayo lethebula, futhi idatha elinganisiwe kufanele irekhodwe.

3, Izisetshenziswa ezidingekayo zokuhlola i-RF

1. Kumadivayisi e-RF angapakishiwe, isiteshi sokuhlola sisetshenziselwa ukufanisa, futhi amathuluzi abalulekile afana nama-spectrograph, ama-vector network analyzer, amamitha kagesi, amajeneretha esignali, ama-oscilloscopes, njll. asetshenziselwa ukuhlola ipharamitha ehambisanayo.
2. Izingxenye ezipakishiwe zingahlolwa ngokuqondile ngamathuluzi, futhi abangani bemboni bamukelekile ukuxhumana.
