SR812st (R) ndi gawo lathu lambiri lakale-loves-loid-offtch matchulidwe ovomerezeka. Ampure-acy-Exprier amatengera mamimba, Gaas, post-Expreer amatengera gawo la Gaas. Zojambula zakale zotsekeredwa ndi zaka 10 zaukadaulo wopanga akatswiri, pangani zida zimakwaniritsa malo abwino. Microprocetuntrocer Kuwongolera, kuwonetsa kwa digito kwa magawo, zopinga zaukadaulo ndizosavuta. Ndi zida zazikulu zomangira amphaka.
Makhalidwe Akugwirira Ntchito
- Kuyankha Kopambana PINEELELCE CITIONS CURE.
- Kapangidwe kalikonse, kupanga njira yopangira SMT, ndipo njira yotsimikizika idapangitsa kuti chithunzithunzi chizikhala chosalala.
- Chip cholumikizira cha RF cholumikizira, chokhala ndi chingwe chabwino cha rf ndi chofanana chofanana.
- Chida cha Gaas, mphamvu zotuluka mosakayika, ndi phindu lalikulu komanso zosokoneza pang'ono.
- Chip Chip Timrocomputer (scm) chowongolera zida kugwira ntchito, LCD limawonetsa magawo, kuvuta komanso kugwirira ntchito, komanso ntchito yokhazikika.
- Kugwiritsa ntchito bwino kwa Agc, pomwe kuyika kwamphamvu kwamphamvu ndi -9 ~ + 2DBM, malo otulutsa amasunga osasinthika, ndi CTB ndi CSBORY.
- Kuphatikizira kulumikizana kwa data, kumatha kulumikizana ndi kalasi ⅱ kasamalidwe ka ma netiweki yoyankha, ndipo mwayi wogwirizana ndi maofesi a pa intaneti.
- Kubwezera kwa Extration kungasankhe njira yotsika kwambiri kuti muchepetse phokoso la phokoso komanso kuchepetsa nambala ya olandila.
Gwirizanitsani Kuyesa
Magawo aluso a bukuli malinga ndi njira yoyeserera kwa gy / t 194-2003
1. Kutumiza koloko kulandila gawo: ndi 10km Stantal Ortic, anive ovennator owoneka bwino, ndi mawonekedwe a Sportical Optical adalemba ulalo woyeserera. Khazikitsani 59 pal-D Analog TV CHINSINSI CHA 45 / 87MHz ~ 550mhz pansi pa kutaya kovomerezeka. Tumizani Kutsatsira Digital Kusinthitsa Kutsatsa kwa 550mhz ~ 862 / 1003Mhz, Kusinthitsa Kusintha kwa Digitor (mu 8 mhz Bandwidth Wonyamula. Pamene olowa magetsi a wolandirayo ndi -2dbm, kuchuluka kwa RF ndi 108dbμv, ndi 9db zotulutsa, yeretsani CTB, CTB, ndi CS, ndi C / N.
2. Kubwezera Kwakumbuyo Kwakumbuyo: Lumikizanani ndi Fleneness ndi NPR DRAMANS PREAMEE NDI MALO OGWIRITSIRA NTCHITO YOPHUNZITSIRA MALO OGULITSIRA NTHAWI ZONSE ZABWINO.
Chidziwitso: Kutalika kwa mawuwo ndi kusinthidwa kwathunthu kwa makina ndikulandila makope am'maso ndi -2dbm, zida zimakwaniritsa gawo lalikulu lolowera lolumikizira. Makina osinthitsa dongosolo amachepetsa (ndiye kuti njira zenizeni zobwezeretsa zimachepetsa), zida zotulutsa zidzachuluka.
Chidziwitso chochezeka: Onani kuti mwakhazikitsa chizindikiro cha RF ku 6 ~ 9DB tandal to equider Engider Interring Proser Index (pansi pa mawonekedwe) a system.
