Introduction
E-199 modulator is high performance headend equipment launched by our company. It is mainly used for adjacent modulation of video and audio signals. With advanced IF PLL technology, it enjoys excellent vestigial sideband characteristic and good out band attenuation. It is the first choice product for medium-sized CATV headend equipment.
Features
l With IF modulation technology and CPU controlled PLL technology, frequency stability is high.
l Selected with high performance SAW filter, and cooperated with spiral band pass filter, it enjoys good out band attenuation.
l With built-in independent RF power amplifier, output level is up to 110dB and more.
l Video modulation depth, audio deviation, A/V ratio and output level are all adjustable on front panel.
l With channel number display on front panel, and added serial power supply ports on rear panel, it is easier to operate.
