Ukuhlola endaweni nge-RF Power Meter

 

Imvamisa, lapho onjiniyela bedinga ukuhlola abasakazi be-FM endaweni, kudingeka izingcezu ezimbalwa zemishini yokusakaza. Nalu uhlu lwesampula:

 

  • Izisetshenziswa zokusakaza ezizohlolwa: isb abasakazi be-FM abanamandla aphezulu
  • Umthwalo we-antenna/dummy: ukuze kudluliselwe isignali ye-RF esakazwayo kusukela kumthumeli
  • Okuphakelayo/amakhebuli: Xhuma i-transmitter kanye ne-antenna noma umthwalo we-dummy, dlulisela isignali ye-RF
  • Imitha yamandla ye-RF: esetshenziselwa ukufanisa imvamisa yedivayisi ngaphansi kokuhlolwa: isb 50-200MHz (VHF) RF wattmeter
  • Amanye amadivayisi ahlobene: Izinzwa zamandla e-RF, nama-spectrum analyzer. Onjiniyela abalungisayo bazokhetha izinzwa zamandla ngokusekelwe kububanzi befrikhwensi, ububanzi obuguqukayo, nefomethi yokushintshashintsha, ngenxa yesikhala esilinganiselwe, lesi sihloko ngeke sithulwe lapha.

 

Ngemuva kwalokho, unjiniyela uzoqinisekisa ukuthi zonke izinto zokusebenza zifakwe izintambo ngokwehlukana ngaphambi kokufaka amandla ku-transmitter, okuhlanganisa:

 

  1. Xhuma ulayini wesidlulisi somthombo womsindo we-FM: kufaka phakathi ukunikezwa kwamandla komthumeli, ukuphuma kwe-RF, okokufaka komsindo, njll.
  2. Xhuma i-antenna yokusakaza ye-FM/i-RF dummy load line: okuhlanganisa okokufaka kwe-RF (isiphakeli/isiphakeli), ukufakwa kwezinti (hlola izigxobo eziphozithivu nezinegethivu, ukuphakama kokufakwa kwezinti, ukukhala kwezimpondo eziningi)
  3. Khetha imitha yamandla ye-RF efanele: okuhlanganisa ukufanisa imvamisa yesidluliseli sokusakaza nesixhumi senzwa yamandla (ama-transmitter e-FM anamandla amakhulu adinga ukuxhunywa epayipini lokuphakelayo, ngakho-ke ungase udinge ukukhetha imitha yamandla e-RF enekhanda elivulekile)

 

Uma konke sekumi ngomumo, unjiniyela uzoxhuma idivayisi ngayinye ngokohlelo "lwe-broadcast transmitter-RF power meter-antenna/dummy load".

 

Isinyathelo sokugcina ukuvula amandla esidluliseli sokusakaza, ulungise amandla okufaka futhi ubheke amandla e-RF imitha yamandla e-RF kanye namanani e-VSWR aboniswa kumitha.

Ungayikhetha kanjani i-RF Power Meter yakho? 5 Izinto Ezibalulekile Okufanele Zikhunjulwe

 

Ukukhetha imitha yamandla e-RF efanele kubalulekile ezintweni zokuhlola, njengoba ukutholwa kwesignali ye-RF okunembile kubaluleke kakhulu kunoma yiluphi uhlelo lokusebenza. Ngakho-ke, kunoma yisiphi isiteshi somsakazo we-FM esifuna amandla e-RF anembe kakhudlwana nezilinganiso ze-VSWR, ungayikhetha kanjani imitha yamandla ye-RF engcono kakhulu? Kunezinto ezimbalwa okufanele uzikhumbule lapho ukhetha imitha yamandla e-RF, okuyizinhlobo, ububanzi be-freq, isibonisi, nekhwalithi yomkhiqizo. Qhubeka ufunda ukuze uthole okwengeziwe!

 

#1 Ukuqonda Izinhlobo

 

Uma ufuna ukuthenga imitha yamandla e-RF, kufanele uqale uqonde uhlobo lwayo. Amamitha kagesi e-RF angahlukaniswa ngokuyisisekelo abe amamitha kagesi e-RF asekelwe ekushiseni, izithonjana ezine-diode-powered, amamitha kagesi e-RF amunca, namamitha okudlula. Imitha yamandla e-RF esekelwe ekushiseni iyisinqumo esihle lapho wenza imisebenzi yokulinganisa edidiyelwe, futhi umtshina osebenza nge-diode uyinketho lapho kudingeka ukufundwa kwezinga eliyisisekelo noma imvelo yesikhashana. Yebo, udinga ukunaka ukuthi imitha yakho yamandla e-RF ifanele yini ukurekhoda amamethrikhi ahlukile njengamandla amaphakathi, amandla okushaya kwenhliziyo, noma amandla emvilophu aphezulu. Nakuba imitha yamandla ye-RF yokumuncwa ifaneleka ukuthola idatha yelabhorethri enembe kakhulu, imitha yamandla edlula i-RF ifanele imisebenzi yasenkambu.

 

#2 I-Frequency Range Nezindaba Zokunemba

 

Ukukhetha ibanga lefrikhwensi elilungile kubalulekile. Ibanga lefrikhwensi elincane liza nephutha elikhulu, isibonelo, uma usebenzisa isidluliseli se-FM esinamabanga asuka ku-88 kuya ku-108Mhz, imitha yamandla ye-RF engu-85-110Mhz iyisinqumo sakho esingcono kakhulu.

 

Uma uvamise ukusebenzisa imitha yamandla e-RF engu-1-200Mhz ukuze uthumele isidluliseli se-FM, khona-ke iphutha laso liyoba likhulu kakhulu kunemitha yamandla e-RF enobubanzi obuncane be-freq. Kungase kubangele izinkinga ezifana nokucaciswa okungalungile kokuphuma kwamandla okuhambisa kanye nothi lwe-VSWR.
