Compensated attenuators yog cov circuits uas yog siv los txo lub sij hawm nce vim tsis muaj zog capacitance los ntawm kev qhia cov capacitors kom sib npaug ntawm cov stray capacitanceNyob rau hauv feem ntau ntawm cov kev siv hluav taws xob, lub amplitude ntawm Lub teeb liab tau nthuav dav nrog kev pab los ntawm lub amplifier.
Tus nqi them rov qab yog dab tsi?
Ib qho nyiaj them poob haujlwm yog ib qho yooj yim ob-chaw nres nkoj network muab qhov ruaj khov voltage attenuation hla ntau zaus band. Cov tes hauj lwm zoo li no yog siv qhov kev ntsuas qhov ntsuas qhov ntsuas qhov tseeb, tshwj xeeb tshaj yog thaum lub teeb liab tsis yog sinusoidal.
Vim li cas thiaj li yuav tau txais cov attenuators tiv thaiv thiab lawv siv qhov twg?
Attenuators yog tsim los hloov qhov loj ntawm lub teeb liab tawm tswv yim pom nyob rau ntawm theem input, thaum nthuav tawm qhov impedance tas li ntawm txhua qhov ntawm lub attenuator input. Kev them nyiaj RC attenuator yuav tsum ua kom txhua zaus sib npaug.
Dab tsi yog qhov ua haujlwm ntawm kev them nyiaj yug attenuator thiab ncua kab hauv ntsug deflection system ntawm oscilloscope?
A Compensated Attenuator yog ib qho yooj yim ob qhov chaw nres nkoj network uas muab qhov kev cuam tshuam tas mus li ntawm ntau qhov ntau zausNtawm no kuv piav qhia cov attenuators thiab them nyiaj hauv cov tswv yim ntawm ntsug deflection amplifiers siv hauv oscilloscopes rau kev piav qhia.
Lub luag haujlwm tseem ceeb ntawm oscilloscope yog dab tsi?
Oscilloscopes (los yog scopes) ntsuas thiab tso tawm qhov hluav taws xob hluav taws xob raws li cov qauv nthwv dej, cov duab sawv cev ntawm qhov hloov pauv ntawm qhov hluav taws xob dhau sijhawm Cov teeb liab tau teeb tsa ntawm daim duab, uas qhia tau hais tias lub teeb liab li cas kev hloov. Kev nkag mus ntsug (Y) sawv cev rau qhov ntsuas hluav taws xob thiab kab rov tav (X) axis sawv cev rau lub sijhawm.
