SA822 Iterambere ry'Ingufu za CATV zo hanze ritazi amazi rirwanya inkuba
Nimero y'icyitegererezo: SA822
Ikirango:Uburibwe bworoshye
MOQ:1
Idapfa amazi kandi ntirinda inkuba
Adopt PHILIPS, NEC modules zikoresha ingufu ziyongera mu mahanga
Igikoresho cyo gufunga no gupima, gihamye cyangwa gishobora guhindurwa
01
Ibisobanuro by'igicuruzwa
1. Incamake y'ibicuruzwa
Ikoreshwa neza mu kohereza ubutumwa mu cyerekezo kibiri (ishobora kubikwa) no kuringaniza ibimenyetso bya kohereza ubutumwa mu byiciro byinshi cyangwa umuyoboro usaba cyane. Adopt PHILIPS, modules za NEC zitumiza ingufu zo gukuba kabiri. Amplifier y'amajwi mbere y'igihe ni amplifier ya microwave tube push-pull amplifier ifite urusaku ruke kugira ngo yizere ko izamuka bihagije. Ifite input 1 n'ibisohoka 2, kandi buri connectivity ifite uburinzi bw'amashanyarazi menshi. Ishami ry'ibisohoka cyangwa ubwikorezi bushobora guhindurwa nyuma yabyo. Hakoreshwa equalizer ebyiri, bityo guhindura ubwikorezi bw'ibisohoka mu byiciro byinshi biroroshye kandi byoroshye. Attenuator na equalizer ni plug-in, bityo abakiriya bashobora guhitamo imiterere idahinduka cyangwa ihinduka. Ingufu zihindagurika cyane (cyangwa ingufu zigororotse) hamwe n'igishushanyo gihamye kidapfa amazi kandi kidapfa inkuba bitanga akazi gahoraho.
