1. INTANGIRIRO
AH2401H ni modulator ifite frequency 24 ihoraho. Izaba ifite amajwi n'amashusho agera kuri 24 mu muhanda ifite amajwi 24 ya televiziyo. Iyi porogaramu ikoreshwa cyane mu mahoteli, mu bitaro, mu mashuri, mu kwigisha hakoreshejwe ikoranabuhanga, mu nganda, mu kugenzura umutekano, mu mashusho ya VOD n'ahandi hantu ho kwidagadurira, cyane cyane mu guhindura televiziyo ya digitale analog, no mu buryo bwo kugenzura buri wese.
2. IBIKORESHO
- Ihamye kandi yizewe
- AH2401H ya buri muyoboro yigenga rwose, uburyo bworoshye bwo gushyiraho umuyoboro
- Uburyo bwa MCU bwo gukoresha frequency yo hejuru na RF, frequency ihamye n'ubuziranenge buri hejuru birakoreshwa
- Imikorere ya buri chips za circuit zihujwe irakoreshwa, kandi ubwizerwe buri hejuru
- Ingufu z'amashanyarazi zifite ubuziranenge, zihoraho amasaha 7x24

Igice cy'imbere
1. Guhindura urwego rw'umusaruro wa RF—Urufunguzo, urwego rw'umusaruro wa RF rushobora guhinduka
2. Guhindura igipimo cya AV—Akabuto gahindura umusaruro w'igipimo cya A / V
3. Guhindura ingano y'ingano y'umusaruro—Gushyiramo akadomo kugira ngo uhindure ingano y'ingano y'umusaruro
4. Guhindura urumuri—Gushyiramo akadomo kugira ngo uhindure urumuri rw'ishusho isohoka
Igice cy'inyuma
A. Umuyoboro w'igerageza: Umuyoboro w'igerageza ry'amashusho, -20dB
B. Umusaruro wa RF: Moduli ya Multiplexer yahinduwe, nyuma yo kuvanga umusaruro wa RF
C. Igenzura ry'umusaruro wa RF: Akadomo, urwego rw'umusaruro wa RF rushobora guhindurwa
D. Ingufu zisohoka mu buryo bwa "power cascade"
Gushyira modulators nyinshi mu mwanya wazo, ushobora gukwirakwiza umusaruro wazo mu zindi modulators z'amashanyarazi kugira ngo ugabanye ikoreshwa ry'amashanyarazi; witondere kudasukiranya inshuro zirenze 5 kugira ngo wirinde umuriro mwinshi.
E. Ingufu zinjira: AC 220V 50Hz/110V 60Hz
