GG-1000M CATV headend fuasgailte as fheàrr RF Modulator
Goirid Tuairisgeul:
GG-1000M CATV headend fuasgailte as fheàrr RF Modulator
feart
1. HF ghiullachd le aon-atharrachadh a 'dèanamh cinnteach ìosal mach còmhlan a' cur bacadh
2. MCU smachd airson smachd tricead agus pongalachd
3. Taisbeanadh LED. Ceithir comharra solais airson gach sianal, a 'cleachdadh suas is sìos gus smachd a chumail air toradh Frequency.
4. Pal, NTSC agus SECAM roghainneil
5. Double Side Band Modulator
