Product Description

CATV Headend RF Analog CATV Modulator RF

Description:

The AH1912M is a 4RU rack mounted chassis that allows for installation of up to 16 pieces microprocessor-controlled

fixed mini-modulators Or 12 pieces agile modulators.Built-in active combiner eliminates unnecessary cabling and potential

connection problem and ensures high output level .All modulators are perfect factory set to desired channel and proper offset.   

Features:

1. Switching power supply for installation flexibility and precise voltage regulation

2. Two cooling fans for long life performance

3. 45dBmV chassis output level,no need extra combiner

4. SAW(surface acoustic wave) filtering on IF for superior in band C/N 5. Front panel access controls enables easy setup
