Chowunikira cha QAM chogwiritsidwa ntchito ndi manja chokhala ndi APP, Power Level ndi MER cha DVB-C ndi DOCSIS, MKQ012

Kufotokozera Kwachidule:

MKQ012 ya MoreLink ndi chipangizo choyezera QAM chonyamulika, chokhala ndi luso loyesa ndikusanthula magawo a QAM a ma netiweki a DVB-C/DOCSIS.

MKQ012 ya MoreLink ndi chipangizo choyezera QAM chonyamulika, chokhala ndi luso loyesa ndikusanthula magawo a QAM a ma netiweki a DVB-C/DOCSIS.

MKQ012 ndi QAM Analyzer yonyamulika, yokhala ndi luso loyesa ndikusanthula magawo a QAM a ma netiweki a DVB-C/DOCSIS. MKQ012 imapereka muyeso weniweni wa ntchito zowulutsa ndi ma netiweki kwa opereka chithandizo chilichonse. Itha kugwiritsidwa ntchito panthawi yokhazikitsa zatsopano kapena ntchito yokonza ndi kukonza magawo a ma netiweki a DVB-C/DOCSIS. Ntchito ya Wi-Fi yophatikizidwa, yomwe imalola wogwiritsa ntchito kupeza deta yoyezera ndi ntchito yolumikizirana ndi APP.

Zinthu Zamalonda

➢ Yosavuta kugwiritsa ntchito ndikusintha ndi APP

➢ Kusanthula Kwachangu kwa Channel

➢ Perekani gulu lothandiza la nyenyezi

➢ Wopanga Spectrum Analyzer Wamphamvu Wophatikizidwa

➢ Zotsatira za muyeso zikuwonetsedwa pafoni yanu yam'manja kudzera pa Wi-Fi

Makhalidwe

➢ Thandizani muyeso ndi kusanthula kwa DVB-C ndi DOCSIS QAM

➢ Thandizo la ITU-J83 Annexes A, B, ndi C

➢ Kusiyanitsa kokha Mtundu wa Chizindikiro cha RF: DOCSIS kapena DVB-C

➢ Chizindikiro cha chenjezo chofotokozedwa ndi ogwiritsa ntchito ndi malire ake, thandizirani ma profiles awiri: pulani A / pulani B

➢ Miyeso yolondola, +/-1dB ya Mphamvu; +/-1.5dB ya MER

➢ Thandizo la TCP / UCP / DHCP / HTTP / SNMP

➢ Thandizani doko limodzi la Ethernet la 10/100/1000 Mbps

➢ Batri Yophatikizidwa

Magawo Osanthula a QAM

➢ 64 QAM / 256 QAM / 4096 QAM (Chosankha) / OFDM (Chosankha)

➢ Kuzungulira Kwambiri: -15dB mpaka +15dB

➢ MER: 20 mpaka 50 dB

➢ Kuwerengera koyenera kwa Pre-BER ndi RS

➢ Kuwerengera kosalondola kwa Post-BER ndi RS

➢ Gulu la nyenyezi

➢ Kuyeza Kupendekeka

Mapulogalamu

➢ Kuyeza kwa netiweki ya chingwe cha digito ya DVB-C / DOCSIS

➢ Kuwunika njira zambiri

➢ Kusanthula kwa QAM kwa nthawi yeniyeni

➢ Kukhazikitsa ndi Kukonza netiweki ya HFC
