VAM 01/DV - Digital-Quality Television IF Modulator

• Digital-quality. The video quality of VAM 01/DV represents the right step just before the 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 modulation quality.
• Compatible with all standards. The VAM 01/DV is fully compatible with all video standards (PAL, NTSC, SECAM) and is available for B,G,M,N,I,D,K,K1 and L modulation 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 with all international standards. This filters outstand for their excellent phase linearity 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.
• Sync restore. An internal sync restore circuit (optional) allows to ripristinate a perfect video sync pulse also with corrupted or scrambled video signal input.
• 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 or dual sound 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 frequency stability or precision offset.
