Detailed Product Description

- Applicable for 47~870MHz system, agile channel output,specially designed for large
scale system .
-  Man machien dialogue function - Vedio frequency AGC function - RS485 net administration function - I2 C Bus control - LCD Display:Radio frequency,Video/Audio medium frequency,Video frequency modulating
scale,Audio frequency modulating deviation,RF output level,A/V ratio,etc
- Audio noise reduction (optional) - Clamping and non-clamping switch,easy for Video frequency scrambler - Intermediate frequency modulating,Video/Audio medium frequency sgnal input,output
port can be applid for interference loading for fee-paid TV system
- In accordance to adjacent frequency design, no interference between adjacent channel

- Having RF automatic amplitude-stabilizing circuit, making front-end system becoming
more stable and reliable .
- RF output adopting modular amplification, ensuring RF output dynamic and parasite
suppressing
- Adopting unique diode dual-balance modulating, good linearity, low noise, modulator's
indexes, such as S/N, C/N, DG, DP, have achieved internationally advanced
level
