RF High Power BroadBand Test Systems Programmable Attenuators
Ma attenuators osinthika ndi zida zamagetsi zomwe zimalola kuwongolera kwa digito ndikusintha moyenera milingo yochepetsera.
Nthawi zambiri amakhala ndi ma attenuators angapo omwe amayendetsedwa ndi ma sign a digito. Ma attenuators osinthika amatha kuwongoleredwa kudzera pa RS-232 kapena mawonekedwe a USB, kupangitsa kuti ikhale yosavuta kuphatikiza mumakina akuluakulu. Poyerekeza ndi ma attenuators osintha pamanja, amapereka kulondola kwambiri komanso kubwerezabwereza, komwe kumakhala kothandiza kwambiri pamapulogalamu omwe amafunikira kusintha pafupipafupi kapena kukonza bwino.
Ma attenuators omwe amatha kukhazikika ali ndi izi:
1. Programmability: Zizindikiro za digito kapena analogi zitha kugwiritsidwa ntchito kuwongolera kutsika, kupondaponda, ndikusintha pakati pamilingo yocheperako komanso mitundu yosiyanasiyana.
2. Kukhazikika: Ili ndi mtengo wokhazikika wochepetsera ndipo nthawi zambiri sichikhudzidwa ndi kutentha kapena zochitika zina zachilengedwe.
3. Kuchita bwino kwambiri: m'magawo osiyanasiyana a engineering electromagnetic minda, ili ndi kuyanjana kwa Electromagnetic, kufanana, kutayika kochepa koyika ndi machitidwe ena abwino kwambiri.
4. Miniaturization: Ikhoza kuphatikizidwa m'mapaketi ang'onoang'ono ndipo imakhala ndi kukula kochepa kwambiri.
Ma attenuators otha kusintha nthawi zambiri amagwiritsidwa ntchito kuyerekezera zochitika zenizeni zapadziko lapansi komanso kutsimikizira momwe zida zimagwirira ntchito pansi pa mphamvu zamphamvu zosiyanasiyana. Amagwiritsidwa ntchito kwambiri pakugwiritsa ntchito, machitidwe olumikizirana opanda zingwe, komanso kupanga ndi kuyesa mabwalo amagetsi ndi zida.
Makamaka, zimaphatikizapo:
1. Njira yolumikizirana: Igwiritseni ntchito posintha mphamvu zamawu opanda zingwe kuti mupewe kukhudzidwa kwamphamvu kwambiri pazida ndi makina.
2. Muyezo wa zida: Chigwiritseni ntchito kuti musinthe pafupipafupi komanso kuti muchepetse kuti mukwaniritse zoyeserera.
3. Zamlengalenga: Pazoyendetsa ndege, luso la zakuthambo, ndi zida zoyendera, zimagwiritsidwa ntchito powongolera dera komanso kuwongolera kuwongolera.
4. Wailesi: Imagwiritsidwa ntchito m'makampani opanga mawayilesi kuwongolera ndikuchepetsa mawilo.
Qualwaveimapereka bandi yotakata komanso zowongolera zosinthika kwambiri pama frequency mpaka 40GHz. Gawolo likhoza kukhala 0.5dB ndipo mtundu wocheperako ukhoza kukhala 80dB kapena kupitilira apo. Othandizira athu okhazikika amagwiritsidwa ntchito kwambiri m'malo ambiri.
