IKUSI MCP-811. Vestigial Side Band twin TV Modulators.
Features
• Vestigial side band twin modulators.
• The twin ones integrate two modulators in one module.
• IF modulation and SAW filtering for maximum harmonic reduction and true VSB response. Adjacent channel operation.
• Frequency agility. Any selectable TV channel within the 45-862 MHz band. PLL frequency synthesized.
• Built-in test pattern generator.
• In twin modulators, the two generated TV channels are combined internally to make up one bi-channel output signal.Technical specifications
