The SK-24M is a 3RU rack mounted chassis that allows for installation of up to 24 pieces microprocessor-controlled fixed mini-modulators.Built-in active combiner eliminates unnecessary cabling and potential connection problem and ensures high output level . All analog modulators are perfect factory set to desired channel and proper offset.

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
6. Rear panel has a combiner loop for easy connection

7. One unit contains 24 pcs fixed adjacent channel modulator card
