Agile Video Modulator - 550 MHz
The VM2551A is designed to accept composite NTSC video and audio inputs from a satellite receiver, video server, off-air demodulator, DVD player, VCR, or similar source. The VM2551A features front panel video and audio over-modulation indicators and level controls to permit easy setup of modulation levels.
The use of frequency synthesis provides complete frequency agility in the 54-550 MHz range using off-air or CATV (STD, IRC, or HRC) channel plans. The use of a superior SAW filter in the IF circuitry allows adjacent channel operation when used with other modulators or signal sources.
An EAS/alternate IF feature allows automatic or manual EAS/AST IF insertion.
