Tirohanga Poto
Ko te kaiwhiwhi whatu SR1002 tā mātou kaiwhiwhi whatu rua-ahunga 1GHz CATV/FTTB hou rawa atu. He whānuitia te whānuitanga o te mana whatu whiwhi, he taumata putanga teitei, he iti hoki te whakamahinga mana. Koinei te taputapu tino pai hei hanga i tētahi whatunga NGB mahi-teitei.
Ngā Āhuatanga Mahi
- Whakamahia te tikanga AGC whatu matatau, te awhe whakahaere AGC whatu: +2dBm ～ -9/-8/-7/-6/-5/-4dBm ka taea te whakarite;
- Ka toro atu te auau mahi whakamua ki te 1GHz, ka whakamahia e te wāhanga whakakaha RF te maramara GaAs iti-kaha mahi teitei, ko te taumata putanga mōrahi ki te 106dBuv;
- Ka whakamahia e EQ me ATT te ara iahiko whakahaere hiko ngaio, kia tika ake ai te whakahaere, kia watea ake ai hoki te whakahaere;
- Kua whakauruhia te kaiwhakautu whakahaere whatunga paerewa akomanga II.
- Tautoko i te whakahaere whatunga mamao (whiringa kore);
- He hanganga kiato, he watea hoki te tāutanga, koinei te taputapu whiriwhiri tuatahi mō te whatunga FTTB CATV;
