Iinkcukacha zeMveliso

I-MKQ128 yi-QAM Analyzer enamandla nesebenziseka lula eyenzelwe ukujonga nokuxela impilo yeDigital Cable kunye nenethiwekhi ye-HFC.

Iyakwazi ukurekhoda rhoqo onke amaxabiso okulinganisa kwiifayile zengxelo kwaye ithumeleI-SNMPimigibe ngexesha langempela ukuba amaxabiso eeparameter ezikhethiweyo angaphezulu kwemida echaziweyo. Ukusombulula ingxakiI-WEB GUIivumela ukufikelela kude/kwasekuhlaleni kuzo zonke iiparameter ezijongiweyo kumaleko we-RF ophathekayo kunye namaleko e-DVB-C / DOCSIS.

Njengoko inani lababhalisile beDigital Cable TV kunye neDOCSIS liqhubeka lisanda kwihlabathi liphela kwaye uMgangatho weNkonzo uye waba yinto ebalulekileyo ekunciphiseni ukuxhaphaka kwababhalisile, iMKQ128 sisixhobo esifanelekileyo sokufezekisa ukubekwa esweni komgangatho ohanjiswa iiyure ezingama-24 ngosuku, iintsuku ezisi-7 ngeveki. Umqhubi wekhebula angayibeka kwindawo ephambili/ekungeneni, kwimayile yokugqibela, okanye kwindawo yababhalisile.

I-MKQ128 yinkqubo engaphantsi njenge-rackmount yokujonga rhoqo iimpendulo ze-frequency/amplitude/constellation/BER kuzo zonke iitshaneli ze-QAM. Ngokusebenzisa ezi parameter zokujonga, umqhubi unokuba negalelo ekulungiseni umba womgangatho wekhebula kwaye afumane indawo apho ukonakala kwe-cable kuchaphazela khona inkonzo.
