Izithasiselo Ezihlelekayo ze-USB RF Digital Step USB Controlled
Ama-attenuator ahlelweyo amadivayisi kagesi avumela ukulawulwa kwedijithali kanye nokulungiswa okunembile kwamazinga okunciphisa.
Ngokuvamile zakhiwe uchungechunge lwezinciphisi ezilawulwa yizibonakaliso zedijithali. Izinciphisi zezinyathelo ezihlelwayo zingalawulwa nge-RS-232 noma i-USB interface, okwenza kube lula ukuhlanganiswa nezinhlelo ezinkulu. Uma kuqhathaniswa nezinciphisi eziguquguqukayo ezenziwe ngesandla, zinikeza ukunemba okuphezulu kanye nokuphindaphindeka, okuwusizo kakhulu ezinhlelweni zokusebenza ezidinga ukulungiswa njalo noma ukulungiswa kahle.
Ama-attenuator e-RF angahlelwa anezici ezilandelayo:
1. Ukuhleleka: Amasignali edijithali noma e-analog angasetshenziswa ukulawula ukuncishiswa, ukunyathela, nokushintsha phakathi kwamazinga nezindlela ezahlukene zokuncishiswa.
2. Ukuzinza: I-USB RF Digital Step Attenuator inenani elizinzile lokunciphisa futhi ngokuvamile ayithinteki izinga lokushisa noma ezinye izimo zemvelo.
3. Ukusebenza okuphezulu: Ezindaweni eziningi zobunjiniyela be-electromagnetic, i-USB attenuator inokuhambisana okuhle kwe-Electromagnetic, ukulingana, ukulahlekelwa okuphansi kokufakwa kanye neminye imisebenzi emihle kakhulu.
4. Ukunciphisa: I-attenuator elawulwa yi-USB ingafakwa emaphaketheni amancane futhi inosayizi omncane kakhulu.
Ama-attenuator alawulwa yi-USB avame ukusetshenziswa ukulingisa izimo zokunciphisa isignali yangempela nokuqinisekisa ukusebenza kwamadivayisi ngaphansi kwezimo ezahlukene zamandla esignali. Asetshenziswa kabanzi ezinhlelweni zokusebenza, ezinhlelweni zokuxhumana ezingenantambo, kanye nokuklama nokuhlola amasekethe kagesi kanye nezingxenye.
Ngokuqondile, i-RF attenuator ehlelwe ihlanganisa:
1. Uhlelo lokuxhumana: Sebenzisa i-attenuator ehlelwe kahle ekulungiseni amandla esignali engenantambo ukuze ugweme umthelela wesignali enamandla kakhulu kumadivayisi nezinhlelo.
2. Ukulinganisa insimbi: Sebenzisa i-attenuator yesinyathelo ehlelekayo ukuze ulungise imvamisa ngokunembile kanye nokunciphisa ukuze kuhlangatshezwane nezidingo zokuhlola.
3. Izindiza: Kwezindiza, ubuchwepheshe basemkhathini, kanye nemishini yokuzulazula, i-USB RF digital step attenuator isetshenziselwa ukulinganisa isekethe kanye nokulawula ukuncipha.
4. Umsakazo: I-USB attenuator isetshenziswa embonini yomsakazo ukulawula nokunciphisa amasignali.
I-Qualwaveinikeza ibhendi ebanzi kanye nama-attenuator anamandla okusebenza asezingeni eliphezulu kuma-frequency afinyelela ku-40GHz. Isinyathelo singaba yi-0.5dB kanti ububanzi bokusebenza bungaba yi-80dB noma ngaphezulu. Ama-attenuator ethu anamandla okusebenza asetshenziswa kabanzi ezindaweni eziningi.
