Aotelega Puupuu
SR812ST(R) o la matou pito sili ona maualuga e lua-output CATV network receiver. O le fa'apipi'i muamua e fa'aaogaina atoa-GaAs MMIC, fa'auma fa'auma e fa'aaogaina le GaAs module. Fa'ata'ita'iga fa'ata'ita'i fa'apitoa fa'atasi ma le 10 tausaga o fa'ata'ita'iga fa'apolofesa fa'apolofesa, fa'apena mea faigaluega e maua ai fa'ailoga lelei fa'atinoga. Pulea Microprocessor, fa'aaliga numera o fa'amaufa'ailoga, fa'ainisinia debugging e sili ona faigofie. O le meafaigaluega autu e fausia ai le CATV network.
Uiga Fa'atinoga
- Tali maualuga PIN photoelectric faagaau liliu.
- Fuafuaga fa'ata'ita'i fa'alelei, gaosiga fa'agasologa o le SMT, ma le ala fa'amanino e fa'amanino atili ai le fa'aliliuina o fa'ailoga photoelectric.
- Faʻapitoa RF attenuation chip, faʻatasi ai ma le lelei RF attenuation ma le paleni laina, maualuga saʻo.
- GaAs fa'apipi'i masini, fa'aluaina le mana, fa'atasi ai ma tupe maua maualuga ma fa'aletonu maualalo.
- Single Chip Microcomputer (SCM) faʻatonutonu meafaigaluega galue, LCD faʻaalia faʻasologa, faʻaoga faigofie ma faʻaogaina, ma faʻatinoga mautu.
- E lelei tele le faatinoga o le AGC, pe a o'o i le －9～＋2dBm le laina o le eletise, e le suia le tulaga o galuega, ma e le suia le CTB ma le CSO.
- Fa'asao feso'ota'iga feso'ota'iga feso'ota'iga, e mafai ona fa'afeso'ota'i ma le vasega Ⅱ tali pulega feso'ota'iga, ma le avanoa i le faiga o le pulega o feso'otaiga.
- Toe fa'afo'i mai e mafai ona filifili le ala pa'u e fa'aitiitia ai le pisa o feso'ota'iga ma fa'aitiitia le numera muamua e talia.
Tulaga Su'ega So'oga
O faʻasologa faʻapitoa o lenei tusi lesona e tusa ai ma le fuaina o le GY / T 194-2003
1. I luma opitika maua vaega: fa'atasi ai ma le 10km fa'ata'ita'iga alava opitika, passive opitika attenuator, ma tulaga opitika transmitter fatuina le su'ega sootaga. Seti le 59 PAL-D analog ala TV fa'ailo ile laina ole 45/87MHz～550MHz i lalo ole feso'ota'iga gau. Tu'u atu le fa'ailoga fa'afuainumera fa'akomepiuta i le tele o le 550MHz~862/1003MHz, o le fa'ailoga fa'afuainumera fa'afuainumera (i le 8 MHz bandwidth) e 10dB maualalo ifo nai lo le maualuga o le ave fa'ailoga analog. A oʻo i le mana faʻapipiʻi faʻaogaina o le mea faʻapipiʻi opitika e -2dBm, o le maualuga o le gaosiga o le RF o le 108dBμV, faʻatasi ai ma le faʻaogaina o le 9dB, fua le C / CTB, C / CSO, ma le C / N.
2. Vaega e felauai mata i tua: So'otaga mafolafola ma NPR dynamic range o fa'asinomaga feso'ota'i lea e aofia ai le fa'asolo i tua ma le pito i tua e maua ai mata.
Fa'aaliga: Afai o le fua fa'atatau o galuega o lo'o fa'atulaga atoa le faiga ma o le mana opitika e maua e -2dBm, e fetaui le masini ma le maualuga o le fa'asologa o feso'ota'iga. A fa'aitiitia le fa'atulagaina o faiga (o lona uiga, fa'aitiitiga o alalaupapa fa'asalalau), o le a fa'atupula'ia le tulaga o mea faigaluega.
Fa'aaliga Faauo: Fautua atu e te setiina le faailo RF i le 6~9dB fa'ailo fa'aulufale i totonu o le fa'aaogaina fa'ainisinia fa'atino e fa'aleleia ai le fa'ailoga e le laina (i lalo o le node) o le uaea.
