Whakawhiti Pūnga Muka, SA120IE
Whakaahuatanga Poto:
Ka hipokina e tēnei whakatakotoranga hua ngā putanga DOCSIS® me EuroDOCSIS® 3.0 o te raupapa hua Embedded Cable Modem Module. Mā te whakamahi i tēnei tuhinga, ka kiia ko SA120IE. Kua whakapakeketia te SA120IE i te pāmahana hei whakauru ki ētahi atu hua e hiahiatia ana hei whakahaere i roto i te taiao o waho, i te taiao pāmahana nui rānei. I runga i te mahi Full Band Capture (FBC), ehara i te mea he Cable Modem anake te SA120IE, engari ka taea hoki te whakamahi hei Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). He mea whakahau te heatsink, ā, he mea motuhake ki te tono. E toru ngā kōhao PCB e whakaratohia ana huri noa i te CPU, kia taea ai te tāpiri i tētahi whāriki heatsink, i tētahi taputapu rite rānei ki te PCB, hei whakawhiti i te wera i puta mai i te CPU ki te whare me te taiao.

Poraka Pūnaha
Kaitiaki o Waho
Ka whakamahia he kaitiaki o waho hei whakarite kia pono te mahi a te pūnaha. Ka panaia te kaitiaki e te
Pūmanawa i ētahi wā, kia kore ai te CM e tautuhi anō. Mena he hapa kei te CM
Pūmanawa, ā, i muri i tētahi wā (wā tirotiro), ka tautuhi aunoa te CM.

Ngā Hononga Papa-ki-Papa i waenga i te Papa Mamati me te Papa CM
E rua ngā papa: ko te papa matihiko me te papa CM, e whakamahi ana i ngā takirua hononga papa-ki-papa e whā hei tuku tohu RF, tohu matihiko me te mana.
E rua ngā takirua hononga MCX e whakamahia ana mō ngā tohu RF o raro me runga o te DOCSIS. E rua ngā takirua hononga Pin Header/PCB e whakamahia ana mō ngā tohu mamati me te hiko. Kei raro i te Papa Mamati te papa CM. Ka whakapā atu te PTM o te CM ki te whare mā te papa wera hei whakawhiti i te wera mai i te PTM ki te whare me te taiao.
Ko te teitei i waenganui i ngā papa e rua he 11.4+/-0.1mm.
Anei te whakaahua o te hononga papa-ki-papa e ōrite ana:
