Introduction E-203 modulator is one economical model of intermediate frequency (IF) modulator elaborately manufactured by our company according to market characteristics in villages and towns. It is applicable to many channels, and features good sideband characteristic, and accurate PLL frequency. It is the modulator that costs almost as low as high frequency (HF) modulator, but gives extraordinarily excellent parameters of performance.
Features l Equipped with IF SAW filter, it has excellent vestigial sideband characteristic. l With simple and optimized circuit design, it enjoys higher reliability. l With CPU controlled PLL, its carrier frequency is accurate, stable. l Video modulation depth, A/V ratio, audio deviation, RF level are all adjustable.
