Briefing

High-quality, high-performance, stable, and reliable fixed channel modulator for 45-860Mhz with advanced IF PLL technology.

Detailed

Introduction

E-2600 is fixed channel modulator designed according to the principle of durability, simplicity, and high performance-price ratio. With its IF modulation circuit, video and audio carrier controlled by CPU PLL, it ensures frequency accuracy and stability. Equipped with proprietary SAW filter that can give real vestigial sideband response characteristic, its spurious rejection is over 60dB. Installed with single pass amplifier, its maximum output level is up to 117dB. Therefore it is applicable to large and medium sized headend system. E-2600 is one synthesized SAW filtered, spiral channel filtered high performance para-broadcasting fixed channel modulator. The product is made and tested completely in accordance with or even better than the parameters recommended by FCC. E-2600 is applicable to all the CATV channels, from standard channel 1 to standard channel 57 (47~866.25MHz).
