Programmable Attenuators USB RF Digital Kauj Ruam USB Tswj
Programmable attenuators yog cov khoom siv hluav taws xob uas tso cai rau kev tswj hwm digital thiab kev hloov pauv ntawm cov qib attenuation.
Lawv feem ntau muaj xws li ib tug series ntawm attenuators tswj los ntawm digital signals. Programmable kauj ruam attenuators tuaj yeem tswj tau los ntawm RS-232 lossis USB interfaces, ua kom yooj yim rau kev koom ua ke rau hauv cov tshuab loj. Piv nrog rau phau ntawv sib txawv ntawm cov attenuators, lawv muab cov neeg raug siab dua thiab rov ua dua, uas yog qhov tseem ceeb heev hauv cov ntawv thov uas yuav tsum tau hloov kho ntau zaus lossis kho kom zoo.
Programmable RF attenuators muaj cov yam ntxwv hauv qab no:
1. Programmability: Digital lossis analog teeb liab tuaj yeem siv los tswj kev attenuation, stepping, thiab hloov ntawm qhov sib txawv attenuation theem thiab hom.
2. Kev ruaj ntseg: USB RF Digital Step Attenuator muaj qhov ruaj khov attenuation tus nqi thiab feem ntau tsis cuam tshuam los ntawm qhov kub thiab txias lossis lwm yam kev mob ib puag ncig.
3. Kev ua haujlwm siab: Nyob rau hauv ntau yam ntawm engineering electromagnetic teb, USB attenuator muaj qhov zoo Electromagnetic compatibility, sib npaug, tsis tshua muaj qhov poob thiab lwm yam kev ua tau zoo.
4. Miniaturization: USB tswj attenuator tuaj yeem muab tso rau hauv cov pob me me thiab muaj qhov me me heev.
USB tswj programmable attenuators feem ntau yog siv los simulate lub ntiaj teb tiag tiag lub teeb liab attenuation scenarios thiab xyuas qhov kev ua tau zoo ntawm cov khoom siv nyob rau hauv cov teeb liab sib txawv zog. Lawv tau siv dav hauv cov ntawv thov, kev sib txuas lus wireless, thiab tsim thiab sim cov khoom siv hluav taws xob thiab cov khoom siv.
Tshwj xeeb, programmable RF attenuator suav nrog:
1. Kev sib txuas lus system: Siv programmable attenuator hauv kev kho cov teeb liab wireless kom tsis txhob muaj kev cuam tshuam ntawm cov teeb liab muaj zog heev ntawm cov khoom siv thiab cov tshuab.
2. Kev ntsuas ntsuas: Siv cov programmable kauj ruam attenuator rau kev hloov kho zaus thiab attenuation kom tau raws li qhov yuav tsum tau ua.
3. Aerospace: Hauv aviation, chaw siv tshuab, thiab cov khoom siv navigation, USB RF digital step attenuator yog siv rau Circuit Court calibration thiab attenuation tswj.
4. Xov tooj cua: USB attenuator yog siv nyob rau hauv xov tooj cua kev lag luam los tswj thiab attenuate signals.
Qualwavemuab broadband thiab siab dynamic range programmable-attenuators ntawm zaus mus txog 40GHz. Cov kauj ruam yuav yog 0.5dB thiab attenuation range tuaj yeem yog 80dB lossis ntau dua. Peb cov programmable-attenuators tau siv dav hauv ntau qhov chaw.
