Incazelo emfushane:
GG-1000M CATV headend beshesha engcono rf modulator
Isici
1. hf kusetshenzwe nomunye Ukuguqulwa kuqinisekisa ongaphakeme aphume band iphazamise
2. MCU ukulawula ukulawula nobuningi kanye nokunemba
3. LED Khombisa. inkomba izibani ezine ukuhlola ichannel yinye ngayinye, usebenzisa UP no-DOWN ukulawula okukhipha Frequency.
4. PAL, NTSC futhi SECAM ozikhethela
5. Side Double Band Modulator
