GG-24M 24 in 1 Headend Fixed channel catv modulator
Goirid Tuairisgeul:
GG-24M 24 ann an 1 Headend Fixed sianal catv Modulator
The GG-24M is a 4RU rack mounted chassis that allows for installation of up to 16 pieces microprocessor-controlled fixed or agile mini-modulators. Built-in active combiner eliminates unnecessary cabling and potential connection problem and ensures high output level.
All modulators Tha seata iomlan factaraidh a 'miannachadh agus sianalan a chothromachadh ceart.
CHOMHARRAN
1. suaip cumhachd airson stàladh sùbailteachd agus mionaideach bholtaids a 'riaghladh
2. Dà fuarachaidh a luchd-leantainn airson beatha fhada coileanaidh
3. 45dBmV chassis toradh ìre, chan eil feum a bharrachd a combiner
4. Chunnaic (uachdar fuaimneach tonn) criathradh air IF airson nas fheàrr ann an còmhlan C / N
5. Beulaibh pannal cothrom smachdan a 'toirt cothrom furasta setup
