Digital Controlled Attenuators
Digital Controlled Attenuator is in magnetron komponint dat kin kontrolearje de attenuation bedrach fia digitale sinjalen.
It ymplemintaasjeprinsipe is om de demping fan it sinjaal te kontrolearjen troch de steat fan 'e ynterne komponint of de grutte fan it ynfiersinjaal oan te passen, de fersetwearde te feroarjen.Yn ferliking mei tradisjonele meganyske attenuators en fariabele wjerstannen.
Digitaal kontroleare attenuators hawwe de folgjende foardielen:
1. Hege presyzje: De digitale kontrôle attenuator kin berikke hege-precision kontrôle fan attenuation troch digitale kontrôle, meastal berikke in krektens fan 0.1dB of minder.
2. Breedbân: Digital kontrolearre attenuators typysk operearje yn de GHz of sels THz berik en hawwe in brede bânbreedte.
3. Grut dynamysk berik: De digitale kontrôle attenuator kin berikke in ferstelbere berik fan 0dB oant 60dB of grutter, en it oanpassing berik is breed.
4. Programmierbere kontrôle: De digitale kontrôle attenuator kin programmearre wurde troch digitale ynterfaces lykas SPI en I2C, mei hege fleksibiliteit.
Digitaal kontroleare attenuators wurde benammen brûkt yn fjilden lykas mikrogolftesten, radar, kommunikaasje en satellytkommunikaasje.Troch de testapplikaasje as foarbyld te nimmen, kin de digitale kontrôleattenuator brûkt wurde om de krêft fan it testsinjaal oan te passen om de gefoelichheid en lineariteit fan 'e DUT (Device Under Test) te mjitten;Kin brûkt wurde om it testsysteem te kalibrearjen om de krektens en konsistinsje te garandearjen;It kin brûkt wurde foar senario's foar simulaasjetesten om de anty-ynterferinsjeprestaasjes fan it systeem te evaluearjen tsjin ferskate ynterferinsje- en kanaalbetingsten.
Qualwaveleveret brede band en hege dynamyske berik digitale kontrolearre attenuators op frekwinsjes oant 40GHz.De stap kin wêze 0.25dB en attenuation berik kin wêze 100dB of sels mear.Us digitale kontrolearre attenuators hawwe goede kwaliteit en hege betrouberens, Mei mear as 70 diel nûmers, dat kin foldwaan oan de behoeften fan ferskillende klanten en wurde in soad brûkt yn meardere fjilden.
