Programmable Attenuators USB RF Digital Gawo USB Yoyendetsedwa
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. Othandizira masitepe 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 osinthika a RF ali ndi izi:
1. Programmability: Zizindikiro za digito kapena analogi zitha kugwiritsidwa ntchito kuwongolera kutsika, kupondaponda, ndikusintha pakati pamilingo ndi mitundu yosiyanasiyana yochepetsera.
2. Kukhazikika: USB RF Digital Step Attenuator ili ndi mtengo wokhazikika wochepetsera ndipo nthawi zambiri sichikhudzidwa ndi kutentha kapena zinthu zina zachilengedwe.
3. Kuchita bwino kwambiri: M'magawo osiyanasiyana a engineering electromagnetic field, USB attenuator ili ndi kugwirizanitsa kwa Electromagnetic, kufanana, kutayika kochepa koyika ndi machitidwe ena abwino kwambiri.
4. Miniaturization: USB controlled attenuator akhoza kuphatikizidwa mu phukusi laling'ono ndipo ali ndi kukula kochepa kwambiri.
Ma attenuators oyendetsedwa ndi USB nthawi zambiri amagwiritsidwa ntchito kuyerekezera zochitika zenizeni zapadziko lapansi ndikutsimikizira momwe zida zimagwirira ntchito pansi pamikhalidwe yosiyanasiyana yamphamvu. Amagwiritsidwa ntchito kwambiri pakugwiritsa ntchito, machitidwe olumikizirana opanda zingwe, komanso kupanga ndi kuyesa mabwalo amagetsi ndi zida.
Makamaka, pulogalamu ya RF attenuator imaphatikizapo:
1. Njira yolumikizirana: Gwiritsani ntchito cholumikizira chokhazikika posintha mphamvu yamawu opanda zingwe kuti mupewe kukhudzidwa kwamphamvu kwambiri pazida ndi makina.
2. Muyezo wa zida: Gwiritsani ntchito chowongolera chowongolera kuti musinthe pafupipafupi komanso kuti muchepetse kuti mukwaniritse zoyeserera.
3. Zamlengalenga: Pazoyendetsa ndege, ukadaulo wapamlengalenga, ndi zida zoyendera, USB RF digito sitepe attenuator imagwiritsidwa ntchito pakuwongolera dera komanso kuwongolera.
4. Wailesi: USB attenuator imagwiritsidwa ntchito m'makampani a wailesi kuwongolera ndikuchepetsa ma siginecha.
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.
