Switched Attenuators Hloov chaw tsuas yog muaj ib qho attenuator kom ua tiav qhov xav tau ntawm attenuation, tus neeg attenuator pads tuaj yeem txuas lossis cascaded ua ke kom nce tus nqi attenuation hauv cov kauj ruam ntawm attenuation.
Koj puas tuaj yeem txuas cov attenuators hauv koob?
Koj yuav tsum tsis txhob sim cascade ob TA197 10: 1 attenuators rau 2 yog vim li cas. Thawj yog kev nyab xeeb - lub attenuator yog ntsuas ntawm 400V max. Siv 2 hauv koob tsis nce qhov kev nyab xeeb ua haujlwm voltage - nws tseem yog 400V.
Koj muab lub attenuator nyob qhov twg?
Qhov no yog qhov zoo tshaj plaws nruab deb ntawm cable modem nce toj, piv txwv li sab nraud ntawm koj qhov chaw nyob ntawm tus kais. Thaum koj attenuate lub upstream frequencies, lub cable modem raug yuam los ntawm CMTS kom nws lub hwj chim, kom "hais lus louder ".
3db attenuator ua dab tsi?
FAM-3 in-line attenuator tuaj yeem yog ntxig rau coaxial cable txau kom txo cov teeb liab. Kev sib xyaw ntawm cov attenuators tuaj yeem siv ua ke los tsim cov teeb liab ploj uas xav tau.
Puas yog tus attenuator yog tus resistor?
Vim ib lub voj voog attenuator tsuas yog passive resistorcov ntsiab lus, nws yog ob qho tib si linear thiab reciprocal.
