Whakaahuatanga Hua
He tirohanga poto
Sr812st (R) Ko ta tatou hou te kaiwhiwhi o te whatunga whatunga Ko te whakauru i mua-amplifier e whakamahi ana i te katoa-GAAS MOG-GAAS, i tukuna e te pou-ampleifier te kōwae Gaas. Ko nga hoahoa raima kua arotau me o maatau 10 nga tau o te wheako hoahoa ngaio, kia tutuki nga taputapu pai ki nga tohu mahi pai. Te Mana Microprocessor, He whakaaturanga mamati o nga tohu, he tino ngawari te Debuging Debugging. Ko te taputapu nui hei hanga i te whatunga Catv.
Nga ahuatanga o te mahi
- - Whakautu Whakautu Whakautu Photoelectric Tube.
- Whakahoahoa Whakahoahoa Whakahoahoa, Tukanga SMT te hanga, me te huarahi tohu tohu kia pai ake te tohu whakaahua whakaahua.
- maramara rf Attentation Motuhake, me te whakamahana RF pai me te raina taurite, te tino tika.
- Gas Avop Crovifier Pūrere, Te Putanga Foobly, me te nui o te hua me te iti o te heke.
- Kotahi te maramara Wicrocomputer (SCM) Whakahaere i nga taputapu e mahi ana, e whakaatu ana te LCD i nga tohu, te waatea me te mahi mohio, me te mahi pumau.
- Ko te mahinga AGC tino pai, i te wa -9 ~ + 2dbm, ko te taumata putanga kaore e rereke, me te CTB me te CSO tonu kaore i rereke.
- Atanga Whakawhitiwhiti Raraunga Rahui, ka taea te hono atu ki te akomanga whakahaere whatunga whatunga, me te uru ki te punaha whakahaere whatunga.
- Ka taea e te waatea te kowhiri i te aratau pakaru ki te whakaheke i te tangi o te tangi me te whakaheke i te nama kaiwhiwhi o te reanga.
Hononga Whakamatau Whakauru
Ko nga tohu hangarau o tenei pukapuka e rite ana ki te tikanga whanganga o te Gy / T 194-2003
1 Whakatakotoria te tohu 59 Pal-D Antalog Channel Channel Channel i te 45 / 87mHz ~ 550mHz i raro i te ngaronga hononga kua tohua. Whakawhiti tohu mo te whakarereke i te 550mHz ~ 862 / 1003mHz, te taumata tohu mo te whakarereke (i te 8 mhz bandwidth) he 10db te iti ake i te taumata whakaingoatanga. I te wa e uru ana te mana o te kaiwhiwhi i te -2dbm, ko te taumata o te RF putanga ko te 108dbjv, me te 9DB Putanga o te 9DB, me whangai i te C / CTB, C / CTS, me C / N.
2.
FAKATOKANGA: A, no te te taumata o te raupaparorohiko ko te whirihora katoa o te punaha ko te -2DBM, ka tutuki nga taputapu mo te taumata nui o te taupū hononga. Ka whakahekehia te whirihoranga punaha (ara, ko nga rarangi whakawhiti ka whakaheke), ka piki ake te taumata o te taputapu.
Panui Whakaipoipo: Whakaarohia kua tautuhia e koe te tohu RF ki te 6 ~ 9DB Tilt i roto i te tono miihini whaihua hei whakapai ake i te taupū korenga (i raro o te kohinga) o te punaha taura.
