Programmable Attenuators USB RF Digital Inyathelo USB elawulwa
I-programmable attenuators zizixhobo zombane ezivumela ulawulo lwedijithali kunye nohlengahlengiso oluchanekileyo lwamanqanaba okunciphisa.
Ngokuqhelekileyo zibandakanya uthotho lwee-attenuators ezilawulwa yimiqondiso yedijithali. Izithinteli ezicwangcisekileyo zinokulawulwa nge-RS-232 okanye ujongano lwe-USB, nto leyo eyenza kube lula ukudibanisa kwiinkqubo ezinkulu. Xa kuthelekiswa ne-attenuators ye-manual variable, zibonelela ngokuchaneka okuphezulu kunye nokuphindaphinda, oku luncedo kakhulu kwizicelo ezifuna ukulungiswa rhoqo okanye ukulungiswa kakuhle.
I-programmable RF attenuators inezi mpawu zilandelayo:
1. Programmability: Iimpawu zedijithali okanye ze-analog zingasetyenziselwa ukulawula ukuthotywa, ukunyathela, kunye nokutshintsha phakathi kwamanqanaba ahlukeneyo kunye neendlela.
2. Uzinzo: I-USB RF Digital Step Attenuator inexabiso elizinzileyo lokunciphisa kwaye idla ngokungachatshazelwa bubushushu okanye ezinye iimeko zokusingqongileyo.
3. Ukusebenza okuphezulu: Kuluhlu olubanzi lweenkalo zobunjineli be-electromagnetic, i-USB attenuator inokuhambelana kakuhle kwe-Electromagnetic, ukulingana, ilahleko ephantsi yokufaka kunye nezinye izinto ezibalaseleyo.
4. I-Miniaturization: I-attenuator elawulwa yi-USB inokudibaniswa kwiiphakheji ezincinci kwaye inobukhulu obuncinane kakhulu.
I-USB elawulwa yi-programmeable attenuators idla ngokusetyenziswa ukulinganisa imeko yokwenyani yophawu lwehlabathi kunye nokuqinisekisa ukusebenza kwezixhobo phantsi kweemeko zamandla omqondiso ezahlukeneyo. Zisetyenziswa ngokubanzi kwizicelo, iinkqubo zonxibelelwano ezingenazingcingo, kunye noyilo kunye novavanyo lweesekethe zombane kunye namacandelo.
Ngokukodwa, i-RF attenuator ecwangcisekileyo ibandakanya:
1. Inkqubo yoNxibelelwano: Sebenzisa i-attenuator ecwangcisiweyo ekulungiseni amandla omqondiso ongenazingcingo ukuphepha impembelelo yemiqondiso eyomeleleyo ngokugqithisileyo kwizixhobo kunye neenkqubo.
2. Umlinganiselo wesixhobo: Sebenzisa isilahlisi esinocwangciso lohlengahlengiso oluchanekileyo kunye nokuthomalalisa ukuhlangabezana neemfuno zovavanyo.
3. I-Aerospace: Kwinqwelomoya, iteknoloji yasemajukujukwini, nakwizixhobo zokuhamba, i-USB RF yedijithali yesithinteli senqanaba ledijithali sisetyenziselwa ulungelelwaniso lwesekethe kunye nolawulo lokuthothisa.
4. Irediyo: Isithinteli se-USB sisetyenziswa kushishino lukanomathotholo ukulawula nokuthomalalisa imiqondiso.
Qualwaveibonelela ngebhendi ebanzi kunye noluhlu oluphezulu oluguquguqukayo olunokucwangciswa-attenuators kumaza ukuya kuthi ga kwi-40GHz. Inyathelo linokuba yi-0.5dB kunye noluhlu lokuthomalalisa lunokuba yi-80dB okanye nangaphezulu. I-programmable-attenuators yethu isetyenziswa ngokubanzi kwiindawo ezininzi.
Inombolo yendawo | Ukuphindaphinda(GHz, min.)  | Ukuphindaphinda(GHz, ubuninzi.) | Uluhlu lokuthomalalisa(dB) | Inyathelo(dB, umz.) | Ukuchaneka(+/-) | Ilahleko yokuFaka(dB, ubuninzi.) | VSWR | Ukutshintsha Ixesha(nS, ubuninzi.) | Amandla(dB, ubuninzi.) | Ixesha lokukhokhela(iiveki) |
