Masu shirye-shiryen Attenuators USB RF Digital Mataki na USB Sarrafa
Shirye-shiryen attenuators su ne na'urorin lantarki waɗanda ke ba da izini don sarrafa dijital da daidaitaccen daidaitawar matakan attenuation.
Yawanci sun ƙunshi jerin na'urorin attenuators da siginar dijital ke sarrafawa. Ana iya sarrafa masu ɗaukar matakan matakai masu shirye-shirye ta hanyar RS-232 ko kebul na musaya, yana sauƙaƙa haɗawa cikin manyan tsarin. Idan aka kwatanta da na'urori masu canzawa na hannu, suna samar da daidaito mafi girma da maimaitawa, wanda ke da amfani sosai a aikace-aikacen da ke buƙatar daidaitawa akai-akai ko daidaitawa.
Masu shirye-shiryen RF na shirye-shiryen suna da halaye masu zuwa:
1. Programmability: Ana iya amfani da siginar dijital ko analog don sarrafa attenuation, mataki, da sauyawa tsakanin matakan attenuation daban-daban da hanyoyi.
2. Kwanciyar hankali: USB RF Digital Step Attenuator yana da tsayayye ƙima kuma yawanci zazzabi ko wasu yanayin muhalli ba ya shafa.
3. Babban aiki: A cikin nau'o'in filayen lantarki na injiniya na injiniya, USB attenuator yana da kyakkyawar daidaitawar Electromagnetic, daidaito, ƙarancin shigarwa da sauran ayyuka masu kyau.
4. Miniaturization: Ana iya haɗa mai sarrafa kebul na USB a cikin ƙananan fakiti kuma yana da ƙananan girman.
Ana amfani da na'urori masu sarrafa shirye-shirye na USB don daidaita yanayin yanayin siginar sigina na gaske da kuma tabbatar da aikin na'urori ƙarƙashin yanayi ƙarfin sigina daban-daban. Ana amfani da su sosai a aikace-aikace, tsarin sadarwa mara waya, da ƙira da gwajin da'irori da kayan aikin lantarki.
Musamman, RF attenuator mai shirye-shirye ya haɗa da:
1. Tsarin sadarwa: Yi amfani da attenuator mai shirye-shirye a daidaita ƙarfin siginar mara waya don guje wa tasirin sigina mai ƙarfi a kan na'urori da tsarin.
2. Ma'auni na kayan aiki: Yi amfani da shirye-shiryen attenuator mataki don daidaitaccen daidaitawar mita da attenuation don saduwa da buƙatun gwaji.
3. Aerospace: A cikin jirgin sama, fasahar sararin samaniya, da kayan kewayawa, USB RF dijital mataki attenuator ana amfani da da'ira calibration da attenuation kula.
4. Rediyo: Ana amfani da kebul attenuator a masana'antar rediyo don daidaitawa da rage sigina.
Qualwaveyana ba da fa'ida mai fa'ida da manyan kewayon shirye-shirye-attenuators a mitoci har zuwa 40GHz. Mataki na iya zama 0.5dB kuma kewayon attenuation na iya zama 80dB ko ma fiye. Ana amfani da shirye-shiryen mu-attenuators a wurare da yawa.
