FMUSER FUTV3627 Gudaha (5W) MMDS 2.5G 2.7G Broadband TV Broadcast DVB-s DVB-t Cod-weyneeye

FMUSER FUTV3627 2.5g Gudbinta hal kanaalka ah waxay caadi ahaan u baahan tahay isku-darka awooda mikrowave si uu isugu daro microwave-yada hal kanaal ah, ka dibna u soo dir anteenada iyada oo loo marayo waveguide. Sidan, awoodda microwave-ka ayaa kor loogu qaadi karaa oo waxay gaari kartaa masaafo dheer. Kanaalka badan ee kanaalka badan ee gudbinta shaqada uma baahna isku-darka awoodda laakiin wuxuu ku xidhaa isha IFKA gudbiyaha iyada oo loo marayo qase. Ka dib beddelka soo noqnoqda, shaandhaynta, iyo xoojinta, waxay u dirtaa calaamada anteenada iyada oo loo marayo waveguide. Sidan, awoodda microwave-ku waa yar tahay masaafada gudbintuna waa gaaban tahay. Gudbiyaha MMDS waxa uu ku siin karaa kanaal calaamad ah oo leh xajmiyeedka ugu badan ee 2.7MHz. Sawaxanka wejiga hooseeya ee oscillator-ka maxalliga ah wuxuu u oggolaanayaa FUTV5 in loo isticmaalo gudbinta calaamadaha analogga iyo dhijitaalka ah. Isticmaalka tignoolajiyada sare-u-qaadista tooska ah ee super-linear-ka waxay kordhin kartaa awoodda gudbinta iyadoo la yareynayo qallooca aan tooska ahayn iyo wadarta isticmaalka tamarta. Sidoo kale, shaqada AGC waxay sii wadi kartaa soo saarista koronto joogto ah, iyo wareegtada ayaa bixin karta ilaalinta VSWR. Dhammaan sifooyinkan ayaa ka dhigaya FUTV200 si ballaaran loogu isticmaalo nidaamyada baahinta.

Faa'iidada

Sawaxanka wejiga oscillator-ka maxalliga ah ee hooseeya, oo diyaar u ah gudbinta analoogga iyo dhijitaalka ah labadaba.

Isticmaalka koronto yar iyo naqshad heer sare ah si loo hagaajiyo awoodda gudbinta, loona yareeyo qallooca aan tooska ahayn.

Ku taageer shaqada AGC oo leh koronto joogto ah si loogu oggolaado gudbiyaha xasilloonida iyo isku halaynta wanaagsan.

Koontaroolka hore ee dhijitaalka ah oo buuxa, hawlgal fudud.

Daaqadda LCD oo muujinaysa awoodda wax soo saarka, heerka attenuator-ka dhijitaalka ah, heerka shaqada AGC/MGC, iyo danab.

Si fudud loo rakibo, muuqaal qurxoon.

Macluumaad la'aan.
