Sibanzi:

Le mveliso yiyo yonke i-state-single-ye-TV eyiTransmitter eQinisekileyo, yamkela ubungakanani bobuchwephesha beTV, kwaye inokusebenzisa ubumbeko olulodwa / udwelise, itshintshe ngokuzenzekelayo.

Le transmitter ineentlobo ngeentlobo zomsebenzi wolungiso kunye non-lomgca wokulinganisa, isithintelo esiphindaphindwayo sokuthwala, kunye ne-bias echanekileyo (enomthombo wangaphandle wokuchaza).

Inokwenza kwangaphambili kwaye ilawule ukuphuma kwemveliso yamandla e-half, kwaye ine-interface yolawulo lwe-telemetry.

Isikhulisi samandla esisebenzisa i-LDMOS FET, i-analog kunye zedijithali zombini ziyahambelana, kwaye sisebenzise amandla aphezulu atshintshisanayo.

Isikhulisi samandla kunye nokuhambisa umbane kusetyenziswa izixhobo ezishushu-iplagi.

Ukupheliswa kwamandla kunye nokuma kwamaza omxube wexesha elinye kuncinci.

Imodyuli yamandla amplifier ibonisa iiparamitha ezisebenzayo ngexesha langempela.

Umatshini uphela unokhuselo lwe-over-yangoku, phezu kobushushu, ngaphezulu kwamandla kunye nomgangatho wamandla ombane okumileyo.

Iscreen sokucofa esibonisa iiparameter ezisebenzayo zoomatshini bonke kunye neemodyuli zamandla ombane (PA) kwinyani yangempela.

I-50W transmitter ifakwe kwi-19inch chassis enye; ilungele isikhululo seTV esiphakathi okanye esincinci.

Iimbonakalo:
● Umatshini uphela ngumjelo omnye, umfanekiso kunye nesandi kunye.
● Ulawulo kunye nokubeka iliso kunengqondo kwaye kunethiwekhi, ine-interface yangaphandle yePC.
● Inokuchongwa kwedatha yobuchwephesha, iinkqubo zokubeka iliso kunye nesoftware ekhompyutheni yokulawula ikhomputha enomsebenzi wovavanyo oluzenzekelayo. Zonke iiparameter zobugcisa zinokufundwa kwipaneli yokubonisa ye-LCD.
● Amanyathelo okhuselo agqibeleleyo anganciphisa ukonakala kwezixhobo. Lo matshini unokukhusela malunga nevidiyo; I-VSWR inkulu kakhulu, igqithisa, iyashukumisa ngaphezulu, ikhusela isigaba sesigaba kunye nokukhusela kombane. Isitshintshi sinokukhuselwa malunga nokugqithisa kakhulu, ngaphezulu, phantsi kwevolthi, ngaphezulu kobushushu, isekethe esifutshane kunye nokukhuseleka kombane.
● Zonke izibonelelo zombane zitshintsha umbane; ukusebenza ngokuphezulu, uluhlu olufanelekileyo lomlawuli, oluqilima ngokutshintsha ukusuka kuguquko lwangaphandle.
● Yamkela umxholo wokuyilwa kwemodyuli.
● Uyilo olushushu olunokutsha: amandla okukhulisa umbane kunye nokutshintsha kwamandla axhasa ishushu-iplagi, kulula ukulungisa ingxaki nokulungiswa; phucula ukuthembakala.
● Ifani yakhiwe kwi-chassis, idlulisa inesakhiwo esidibeneyo kunye nesimo esihle.
