I-1RU QAM Analyzer enefu, izinga lamandla kanye ne-MER kokubili i-DVB-C kanye ne-DOCSIS, i-MKQ124

Incazelo emfushane:

I-MKQ124 iyi-QAM Analyzer enamandla futhi esebenziseka kalula ehloselwe ukuqapha nokubika impilo ye-Digital Cable kanye nenethiwekhi ye-HFC.

Iyakwazi ukurekhoda ngokuqhubekayo wonke amanani okulinganisa kumafayela ombiko nokuthumelaI-SNMPizithiyo ngesikhathi sangempela uma amanani epharamitha akhethiwe angaphezu kwemingcele echaziwe. Ukuxazulula inkingaI-WEB GUIivumela ukufinyelela okukude/kwasendaweni kuzo zonke izinhlaka eziqashwe kusendlalelo se-RF esingokoqobo kanye nezendlalelo ze-DVB-C / DOCSIS.

I-MKQ124 iyi-QAM Analyzer enamandla futhi esebenziseka kalula ehloselwe ukuqapha nokubika impilo ye-Digital Cable kanye nenethiwekhi ye-HFC.

Iyakwazi ukubhalisa ngokuqhubekayo wonke amanani okulinganisa kumafayela ombiko nokuthumela izicupho ze-SNMP ngesikhathi sangempela uma amanani amapharamitha akhethiwe ngaphezu kwemingcele echaziwe. Ukuze kuxazululwe inkinga, i-WEB GUI ivumela ukufinyelela okukude/kwasendaweni kuwo wonke amapharamitha aqashwe kusendlalelo se-RF esingokoqobo kanye nezendlalelo ze-DVB-C / DOCSIS.

I-MKQ124 iyi-QAM Analyzer enamandla futhi esebenziseka kalula ehloselwe ukuqapha nokubika impilo ye-Digital Cable kanye nenethiwekhi ye-HFC.

Njengoba inani lababhalisile be-Digital Cable TV kanye ne-DOCSIS liqhubeka landa emhlabeni wonke futhi ikhwalithi yesevisi isibe yinto ebalulekile ekunciphiseni ukungasebenzi kwababhalisile, i-MKQ124 iyithuluzi elifanele lokufeza ukuqapha okungabizi amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto, izinga elilethwa kuzo zonke izindawo zenethiwekhi ye-Digital Cable. Umqhubi wekhebula angayibeka endaweni eyinhloko/esikhungweni, ngemayela lokugcina, noma endaweni yababhalisile.

I-MKQ124 iyisistimu encane njenge-rackmount yokuqapha njalo izimpendulo zemvamisa/i-amplitude/i-constellation/i-BER zazo zonke iziteshi ze-QAM. Ngokusebenzisa lezi zinhlaka zokuqapha, umqhubi angasebenza ngokushesha ekulungiseni inkinga yekhwalithi yekhebula futhi athole indawo lapho ukuwohloka kuphazamisa khona isevisi.
