Tlhaloso ea Sehlahisoa
SFT3402E ke modulator e sebetsang hantle haholo e ntlafalitsoeng ho latela maemo a DVB-S2 (EN302307) e leng tekanyetso ea moloko oa bobeli oa likhokahano tsa satellite tsa Europe. Ke ho fetolela lipontšo tsa ASI le tsa IP ka tsela e 'ngoe hore e be sephetho sa dijithale sa DVB-S/S2 RF.
BISS scrabling mode e kenngoa ho modulator ena ea DVB-S2, e thusang ho aba mananeo a hau ka mokhoa o sireletsehileng. Ho bonolo ho fihlella taolo ea lehae le e hole ka software ea NMS ea Web-server le LCD ka phanele e ka pele.
Ka moralo oa eona o theko e phahameng haholo, modulator ena e sebelisoa hampe bakeng sa khaso, lits'ebeletso tsa puisano, pokello ea litaba le lits'ebetso tse ling tsa sathelaete tsa Broadband.
Likarolo tsa Bohlokoa
- Ho lumellana ka botlalo le DVB-S2 (EN302307) le DVB-S (EN300421) standard
- Lisebelisoa tse 4 tsa ASI (3 bakeng sa bekapo)
- Tšehetso ea pontšo ea IP (100M).
- QPSK, 8PSK, 16APSK, 32APSK Lihlopha tsa Linaleli
- Ts'ehetsa maemo a RF CID (Ho ikhethela joalo ka taelo)
- Mocheso oa kamehla oa kristale oscillator, o phahameng joalo ka 0.1ppm botsitso
- Ts'ehetso ea ho kopanya tlhahiso ea oache ea 10Mhz ka koung ea tlhahiso ea RF
- Tšehetsa tlhahiso ea matla a 24V ka boema-kepe ba RF
- Ts'ehetsa ho qhekella ha BISS
- Tšehetsa phetiso ea SFN TS
- Phatlalatso ea maqhubu: 950 ~ 2150MHz, 10KHz ho hata
- Ts'ehetsa taolo ea lehae le e hole ka NMS ea Web-server
