I-MKQ124 inamandla kwaye isebenziseka lula i-QAM Analyzer enenjongo yokubeka iliso kunye nokuxela impilo yeDigital Cable kunye nenethiwekhi yeHFC.

Iyakwazi ukuloga ngokuqhubekayo onke amaxabiso emilinganiselo kwiifayile zengxelo kunye nokuthumela imigibe ye-SNMP ngexesha lokwenyani ukuba ixabiso leeparamitha ezikhethiweyo ngaphezu kwemida echaziweyo.Ukusombulula ingxaki i-WEB GUI ivumela ukufikelela kude / kwendawo kuzo zonke iiparamitha ezibekwe esweni kumaleko weRF ebonakalayo kunye neDVB-C / DOCSIS umaleko.

I-MKQ124 inamandla kwaye isebenziseka lula i-QAM Analyzer enenjongo yokubeka iliso kunye nokuxela impilo yeDigital Cable kunye nenethiwekhi yeHFC.

Njengoko inani lababhalisi be-Digital Cable TV kunye nababhalisile be-DOCSIS lihlala lisanda kwihlabathi jikelele kwaye uMgangatho weNkonzo uye waba yinto ebalulekileyo ekunciphiseni ukuchithwa kwababhalisi, i-MKQ124 sisixhobo esifanelekileyo sokufezekisa iindleko ezingabizi kakhulu ze-24/7 zokuhlola umgangatho ohanjiswe kuzo zonke iindawo Digital Cable network.Umsebenzisi wentambo unokuyisebenzisa kwi-headend / hub, ecaleni kwemayile yokugqibela, okanye kwindawo yomrhumi.

I-MKQ124 yinkqubo engaphantsi njenge-rackmount ukujonga ngokuqhubekayo i-frequency / amplitude / constellation / BER iimpendulo kuzo zonke iziteshi ze-QAM.Ngokusebenzisa ezi parameters zokubeka iliso, umqhubi unokuthatha inyathelo ekulungiseni umba womgangatho wentambo kunye nokubeka indawo apho ukuthotywa kuchaphazela inkonzo.
