RF High Power BroadBand Test Systems Programmable Attenuators
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, li 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 ho phahameng le ho pheta-pheta, tse thusang haholo lits'ebetsong tse hlokang ho lokisoa khafetsa kapa ho lokisoa hantle.
Li-attenuators tse ka khonehang 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: 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 tsa boenjiniere ba motlakase oa motlakase, e na le ts'ebelisano e ntle ea Electromagnetic, tekano, tahlehelo e tlaase ea ho kenya le lits'ebetso tse ling tse babatsehang.
4. Miniaturization: E ka kopanngoa le liphutheloana tse nyenyane 'me e na le boholo bo fokolang haholo.
Li-attenuators tse ka reroang hangata li sebelisoa ho etsisa maemo a phokotso ea mats'oao a lefats'e le ho netefatsa ts'ebetso ea lisebelisoa tlasa 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, e kenyelletsa:
1. Sistimi ea likhokahano: E sebelise ho lokisa matla a mats'oao a waelese ho qoba tšusumetso ea mats'oao a matla ho feta lisebelisoa le lits'ebetso.
2. Tekanyo ea seletsa: E sebelisetse ho lokisa khafetsa le ho theola maikutlo ho fihlela litlhoko tsa tlhahlobo.
3. Sepakapaka: Sebakeng sa lifofane, theknoloji ea sepakapaka, le thepa ea ho sesa, se sebelisetsoa ho lekanya potoloho le taolo ea ho fokotsa matla.
4. Seea-le-moea: Se 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. Mohato o 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.
