Agile Video Modulator

Product Description

The ***0M is a professional quality, agile audio/video modulator., Which can be used as an alternate IF and is specifically designed for use of Headend systems of CATV. This product provide audio and video modulated RF carrier on any channel in the *5 to **0MHz frequency range. Many standard audio/video sources can be used, such as satellite receivers and video tape recorders. This modulator has a wide range of standard and optional features that make it very suitable for advanced CATV systems. A custom SAW filter is employed to provide true vestigial sideband selectivity to delay pre-distortion. This modulator has an external IF loop which allows interfacing with video all-call and signal scrambling system. The Product features rock solid. Frequency selection is accomplished via front panel channel up/down s with LED channel readout for easy on-the-fly channel changes. A channel lockout mode is also provided to prevent accidental channel changes.
