GG 16 16 1 CATV atathana njira headend modulator
Short Description:
GG-16M 16 1 CATV atathana njira headend modulator
The GG-16M ndi 4RU pachithandara wokwera galimotoyo kuti amalola unsembe wa ku 16 zidutswa microprocessor womwe lokhazikika kapena agile mini-modulators. Anamanga-yogwira combiner kumatha cabling zosafunika ndi kuthekera vuto kugwirizana ndi zipangitsa mkulu linanena bungwe mlingo.
modulators zonse ziri zangwiro fakitale akonzeratu njira anakhumba ndi choyenera kuchepetsa.
MAWONEKEDWE
1. Pogwiritsanso magetsi kusinthasintha unsembe yeniyeni voteji lamulo
2. awiri mafani kuzirala kuchitila yaitali moyo
3. 45dBmV galimotoyo linanena bungwe msinkhu, sipafunika owonjezera combiner
4. SAW (padziko lamayimbidwe yoweyula) zosefera pa Ngati amphamvu gulu C / N
5. Front amazilamulira gulu mwayi chimathandiza zosavuta khwekhwe
