Detailed Product Description

- Applicable for 47~870MHz system, fixed 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
- Surface mount technology, ensuring the accordance of entire machine- 19' 1U standard structure, independent power supply, elegant exterior designSpecification:- RF:IF 38MHzoutput return loss ≥15 dB (VHF) ≥ 12 dB (UHF)output level ≥ 120 dBμV (typical value)C/N ≥ 65 dB (fc ± 4 MHz) ≥ 70 dB (fc ± 8 MHz) ≥ 80 dB (fc ± 16 MHz)spurious output suppression ≥ 68 dB- Video:input level 1.0 Vp-pvideo modulating rate 87.5 %deferential gain ≤ 2 % deferential degree ≤ 2 'video in-band flatness ≤ ± 0.75 dBvideo S/N ≥ 58 dB (non coefficient added) ≥ 64 dB (coefficient added)- Audio:audio deviation ± 50 KHzaudio in-band flatness ≤ ± 0.5 dB(40Hz~15KHz)audio distortion degree ≤ 1 %audio S/N ≥ 65 dB
