Description:Feature Human-oriented design such as LCD display of RF, Video/Audio intermediate frequency, Video modulation rate, Audio partial frequency and RF output voltage; optional function of reducing noise. Designed by adjacent channel transmission standard, no interference between adjacent channels;Input and output of Video/Audio intermediate frequency signal used for scrambling subscription CATV system. Oscillator using unique phase-lock(PLL) circuit makes phase noise extremely low, makes video clear and stable, creates auto amplitude-fixed RF circuit and causes head-end system stable and reliable. Using dual-balancing diode modulation with fine linearity and low noise, fine indexes including signal to noise ratio(S/N), carrier noise rate(C/N), differential gain(DG) and differential phase(DP) as good as those of import slap-up modulators. 19-inch standard structure, independent power supply, flexible fit out, elegant appearance, firm structure, nice electromagnetism shield and convenient operation and maintenance.
