A/V IF Modulators
VAM 01/DVL
° Digital-quality. The video quality of VAM 01/DV represents the right step just before the next DTV generation. Using a new back-porch clamping circuit, combined with a full band linearity corrector it’s possible to obtain a perfect video quality with negligible distortions and intermodulations. All this means a superior video quality with only a slight difference compared with digital TV.

° Compatible with all standard composite video and audio signals (PAL, NTSC, SECAM). Available for B,G,M,N,I,D,K,K1 and L systems. VAM 01/DV professional multistandard modulator is designed to produce sound and vision modulated signals at any standard intermediate frequency.

° Vestigial sideband SAW filter. For a perfect vestigial sideband modulation an high quality SAW filter is used complying all international standards. This filters outstand for their excellent linear phase and flat pass-band and group-delay characteristics.

° Group delay precorrection. TV receiver group delay precorrection is available for all standards (optional).

° White clipper. The white clipper is factory set to guarantee the best modulation quality.

° PLL sound carrier. Sound and video intercarrier is synchronized by PLL to video line frequency for maximum stability and negligible intermodulations.

° Stereo and dual sound. Available with dual sound facility (optional) for stereo transmissions.

° Panel metering. Full front panel metering and control for complete setting and performance checking.

° Input for external frequency synchronization. Input for external frequency synchronization is available for higher stability or precision offset.
