Programmable Attenuators USB RF Digital Mohato USB Controled
Li-attenuators tse ka reroang ke lisebelisoa tsa elektroniki tse lumellang taolo ea dijithale le tokiso e nepahetseng ea maemo a phokotso.
Hangata li na le letoto la li-attenuators tse laoloang ke matšoao a dijithale. Li-attenuators tse ka reroang li ka laoloa ka RS-232 kapa li-interface tsa USB, ho etsa hore ho be bonolo ho li kopanya le lits'ebetso tse kholoanyane. Ha ho bapisoa le li-attenuators tse feto-fetohang ka letsoho, li fana ka ho nepahala le ho pheta-pheta ho holimo, tse thusang haholo lits'ebetsong tse hlokang ho lokisoa khafetsa kapa ho lokisoa hantle.
Li-attenuators tsa RF tse hlophisitsoeng li na le litšobotsi tse latelang:
1. Programmability: Lipontšo tsa digital kapa analog li ka sebelisoa ho laola ho fokotseha, ho hata le ho fetoha pakeng tsa maemo a fapaneng a ho fokotsa le mekhoa.
2. Botsitso: USB RF Digital Step Attenuator e na le boleng bo tsitsitseng ba attenuation mme hangata ha e amehe ke mocheso kapa maemo a mang a tikoloho.
3. Ts'ebetso e phahameng: Libakeng tse ngata tse fapaneng tsa masimo a motlakase oa boenjiniere, USB attenuator e na le ts'ebelisano e ntle ea Electromagnetic, tekano, tahlehelo e tlase ea ho kenya le lits'ebetso tse ling tse ntle haholo.
4. Miniaturization: Attenuator e laoloang ke USB e ka kenngoa ka har'a liphutheloana tse nyenyane 'me e na le boholo bo fokolang haholo.
Li-attenuators tse laoloang ke USB li atisa ho sebelisoa ho etsisa maemo a ho fokotsa matšoao a sebele lefatšeng le ho netefatsa ts'ebetso ea lisebelisoa tlas'a maemo a fapaneng a matla a mats'oao. Li sebelisoa haholo lits'ebetsong, lits'ebetsong tsa puisano tse se nang mohala, le moralo le tlhahlobo ea lipotoloho le likarolo tsa elektroniki.
Haholo-holo, programmable RF attenuator e kenyelletsa:
1. Sistimi ea likhokahano: Sebelisa attenuator e lokiselitsoeng ho lokisa matla a leqhubu la waelese ho qoba tšusumetso ea mats'oao a matla ho feta lisebelisoa le lits'ebetso.
2. Tekanyo ea lisebelisoa: Sebelisa attenuator e ka lokisoang bakeng sa tokiso e nepahetseng ea khafetsa le ho theola maikutlo ho fihlela litlhoko tsa tlhahlobo.
3. Sefofane sa sefofane: Sebakeng sa lifofane, theknoloji ea sebaka, le lisebelisoa tsa ho tsamaisa, USB RF digital step attenuator e sebelisoa bakeng sa ho lekanya potoloho le taolo ea ho fokotsa.
4. Radio: USB attenuator e sebelisoa indastering ea seea-le-moea ho laola le ho fokotsa matšoao.
Qualwavee fana ka li-band tse pharalletseng le li-attenuators tse phahameng tse matla tse ka khonehang ho fihla ho 40GHz. Bohato bo ka ba 0.5dB mme sebaka sa attenuation se ka ba 80dB kapa ho feta. Li-programmable-attenuators tsa rona li sebelisoa haholo libakeng tse ngata.
