Ii-Attenuators eziCwangcisiweyo ze-USB RF Digital Step USB Controlled
Izithinteli ezicwangcisiweyo zizixhobo ze-elektroniki ezivumela ulawulo lwedijithali kunye nokulungiswa ngokuchanekileyo kwamanqanaba okunciphisa.
Ngokwesiqhelo ziquka uthotho lwee-attenuators ezilawulwa ziimpawu zedijithali. Ii-attenuators ze-step ezinokucwangciswa zinokulawulwa nge-RS-232 okanye i-USB interfaces, okwenza kube lula ukuzidibanisa kwiinkqubo ezinkulu. Xa kuthelekiswa nee-attenuators eziguquguqukayo ezenziwe ngesandla, zibonelela ngokuchaneka okuphezulu kunye nokuphindaphinda, okuluncedo kakhulu kwizicelo ezifuna ukulungiswa rhoqo okanye ukulungiswa kakuhle.
Ii-attenuators ze-RF ezinokucwangciswa zineempawu ezilandelayo:
1. Ukucwangciswa kweenkqubo: Imiqondiso yedijithali okanye ye-analog ingasetyenziselwa ukulawula ukuncitshiswa, ukunyathela, kunye nokutshintsha phakathi kwamanqanaba ahlukeneyo okuncitshiswa kunye neendlela.
2. Uzinzo: I-USB RF Digital Step Attenuator inexabiso elizinzileyo lokunciphisa kwaye ayisoloko ichatshazelwa bubushushu okanye ezinye iimeko zokusingqongileyo.
3. Ukusebenza okuphezulu: Kwiinkalo ezahlukeneyo zobunjineli be-electromagnetic, i-USB attenuator inokuhambelana okuhle kwe-Electromagnetic, ukulingana, ilahleko ephantsi yokufakwa kunye neminye imisebenzi emihle kakhulu.
4. Ukunciphisa i-Miniaturization: I-attenuator elawulwa yi-USB ingafakwa kwiipakethe ezincinci kwaye inobukhulu obuncinci kakhulu.
Izithinteli ezicwangcisiweyo ze-USB ezilawulwa yi-USB zihlala zisetyenziswa ukulinganisa iimeko zokunciphisa isignali yehlabathi lokwenyani kunye nokuqinisekisa ukusebenza kwezixhobo phantsi kweemeko ezahlukeneyo zamandla esignali. Zisetyenziswa kakhulu kwizicelo, kwiinkqubo zonxibelelwano ezingenazingcingo, kunye noyilo kunye novavanyo lweesekethe ze-elektroniki kunye nezinto.
Ngokukodwa, i-attenuator ye-RF ecwangcisiweyo ibandakanya:
1. Inkqubo yonxibelelwano: Sebenzisa i-attenuator ecwangcisiweyo ekulungiseni amandla esignali engenazingcingo ukuze uphephe impembelelo yesignali enamandla kakhulu kwizixhobo nakwiinkqubo.
2. Ukulinganisa izixhobo: Sebenzisa i-attenuator yesinyathelo enokucwangciswa ukuze ulungise ngokuchanekileyo i-frequency kunye ne-attenuation ukuze uhlangabezane neemfuno zovavanyo.
3. I-Aerospace: Kwizixhobo zeenqwelo-moya, iteknoloji yasemajukujukwini, kunye nezixhobo zokuhamba, i-USB RF digital step attenuator isetyenziselwa ukulinganisa iisekethe kunye nokulawula ukuncipha.
4. Irediyo: Isixhobo sokuthomalalisa i-USB sisetyenziswa kushishino lwerediyo ukulawula nokunciphisa imiqondiso.
I-Qualwaveibonelela ngebhendi ebanzi kunye nee-attenuators ezicwangciswayo ezinokusetyenziswa kwii-frequency ezifikelela kwi-40GHz. Inqanaba lingaba yi-0.5dB kwaye uluhlu lokuncitshiswa lungaba yi-80dB nangaphezulu. Ii-attenuators zethu ezicwangciswayo zisetyenziswa kakhulu kwiindawo ezininzi.
