Fix Modulator without IF Loop

Description

Features

Part Number : NTX-F8600

The Fix Modulator (NTX-F8600) series fixed type adjacent channel television modulator is high-performance type head-end equipment, and mainly used as video and audio signal adjacent channel modulating. The equipment adopts advanced if-frequency dealing and PLL technology, high frequency stability and small signal distortion. Suitable for constructing large or middle-size CATV system.
