وصف
وصف:
The AH1916 is a 4RU rack-mounted chassis that allows for installation of up to 16 pieces of microprocessor-controlled
fixed mini-modulators Or 12 pieces agile modulators. Built-in active combiner eliminates unnecessary cabling and potential
connection problem and ensures a high output level. All modulators are perfect factory set to the desired channel and proper offset.
سمات:
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 for extra combiner,
4. SAW(surface acoustic wave) filtering on IF for superior in-band C/N 5. Front panel access controls enable an easy setup.
