FeatureHuman-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.SpecificationsVideo input amplitude1Vp-p(whole TV signal, positive)Video input impedance75W(lotus flower plug seat)Audio input amplitude0.775VAudio input impedance10KW(Imbalance lotus flower plug seat)Degree of video modulation signal&ge 87.5%Video flatness&le75dBPhase of differential coefficient&le2Gain of differential coefficient&le2%Delay difference of color or light&le30nsVideo signal to noise ratio&ge 58dB(unweighted)&ge64dB(weighted)Output frequency45&sim870MHzFrequency accuracy&le1KHzTotal Frequency deviation&le5KHzOutput level of video carrier&ge120dBmVAdjusting range of output level0&sim15dBAudio carrier power to video carrier power ratioNegative 10&simnegative20dBCarrier to noise ratio(C/N)&ge65dB(fc MHz)&ge70dB(fc MHz)&ge80dB(fc 6MHz)RF output impedance75WOutput suppression&ge65dBError of video/audio carrier interval&le5KHzMaximum partial frequency of audio0KHzPre-emphasis of audio50msAudio flatness(40Hz~15KHz)&le5dBDistortion degree of audio&le1%Audio signal to noise ratio&ge60dBCarrier to inter-modulation ratio&ge 60dBOutput Return loss&ge 15dB(VHF)&ge12dB(UHF)Power supply220V AC10% 50Hz 20VADimension19" Standard structureFixing dimension465 1.8mm
