RF coaxial hloov yog ib qho cuab yeej siv hauv RF thiab microwave kev sib txuas lus los tsim lossis hloov kev sib txuas ntawm txoj kab sib txawv coaxial. Nws tso cai rau kev xaiv ntawm ib qho kev tawm tswv yim lossis kev tso tawm los ntawm ntau txoj kev xaiv, nyob ntawm qhov xav tau kev teeb tsa.
Cov yam ntxwv hauv qab no:
1. Kev hloov ceev: RF coaxial keyboards tuaj yeem hloov pauv sai ntawm txoj kev sib txawv RF teeb liab, thiab lub sijhawm hloov pauv feem ntau yog qib millisecond.
2. Kev poob qis qis: Cov qauv hloov pauv yog compact, tsis tshua muaj teeb liab poob, uas tuaj yeem ua kom muaj kev sib kis ntawm cov teeb liab zoo.
3. Kev sib cais siab: Qhov hloov pauv muaj kev sib cais siab, uas tuaj yeem txo qhov kev cuam tshuam ntawm cov teeb liab.
4. Kev ntseeg siab: RF coaxial hloov tau txais cov ntaub ntawv zoo thiab cov cuab yeej tsim khoom siab, uas muaj kev ntseeg siab thiab ruaj khov.
