I-Attenuators Ehlelekayo ye-USB RF Digital Isinyathelo se-USB esilawulwa
Ama-attenuators ahlelekayo amadivaysi e-elekthronikhi avumela ukulawula kwedijithali nokulungiswa okunembile kwamaleveli okuncisha.
Ngokuvamile ahlanganisa uchungechunge lwama-attenuators alawulwa amasignali edijithali. Izinqamuleli zezinyathelo ezihlelekayo zingalawulwa nge-RS-232 noma nge-USB interface, okwenza kube lula ukuzihlanganisa kumasistimu amakhulu. Uma kuqhathaniswa nama-attenuators aguquguqukayo okwenziwa ngesandla, ahlinzeka ngokunemba okuphezulu nokuphindaphinda, okuwusizo kakhulu ezinhlelweni ezidinga ukulungiswa njalo noma ukulungiswa kahle.
Ama-attenuators e-RF ahlelekayo anezici ezilandelayo:
1. Ukuhleleka: Amasiginali edijithali noma e-analogi angasetshenziswa ukulawula ukuncipha, ukunyathela, kanye nokushintsha phakathi kwamazinga ahlukene nezindlela zokunciphisa.
2. Ukuzinza: I-USB RF Digital Step Attenuator inenani eliqinile lokunciphisa futhi ngokuvamile alithintwa izinga lokushisa noma ezinye izimo zemvelo.
3. Ukusebenza okuphezulu: Ezinkambini eziningi zobunjiniyela be-electromagnetic, i-USB attenuator inokuhambisana okuhle kwe-Electromagnetic, ukulingana, ukulahleka kokufakwa okuphansi nokunye ukusebenza okuhle kakhulu.
4. I-Miniaturization: I-attenuator elawulwa yi-USB ingahlanganiswa namaphakheji amancane futhi inosayizi omncane kakhulu.
Izinqamuleli ezilawulekayo ezilawulwa nge-USB zivame ukusetshenziselwa ukulingisa izimo zokuncisha isignali yomhlaba wangempela kanye nokuqinisekisa ukusebenza kwamadivayisi ngaphansi kwezimo zamandla esignali ezihlukile. Asetshenziswa kakhulu ezinhlelweni zokuxhumana ezingenantambo, kanye nokwakhiwa nokuhlolwa kwamasekethe kagesi kanye nezingxenye.
Ngokukhethekile, i-RF attenuator ehlelekayo ihlanganisa:
1. Isistimu yokuxhumana: Sebenzisa isibaliseli esihlelekayo ekulungiseni amandla esignali engenantambo ukuze ugweme umthelela wamasignali aqine ngokwedlulele kumadivayisi namasistimu.
2. Ukulinganisa insimbi: Sebenzisa isibambisi isinyathelo esihlelekayo ukuze ulungise kahle imvamisa kanye nokuncishiswa ukuze uhlangabezane nezidingo zokuhlola.
3. I-Aerospace: Kwezokundiza, ubuchwepheshe basemkhathini, namathuluzi okuzulazula, i-USB RF digital step attenuator isetshenziselwa ukulinganisa isekethe nokulawula ukuncisha.
4. Umsakazo: I-USB attenuator isetshenziswa embonini yomsakazo ukuze ulawule futhi unciphise amasignali.
Qualwaveihlinzeka ngebhendi ebanzi kanye nezihlanganisi ezihlelekayo ezisezingeni eliphezulu kumafrikhwensi afika ku-40GHz. Isinyathelo singaba ngu-0.5dB futhi ububanzi bokunciphisa bungaba ngu-80dB noma ngisho nangaphezulu. Ama-attenuators ethu ahlelekayo asetshenziswa kabanzi ezindaweni eziningi.
