Dab tsi yog cov peev txheej ntawm cov khoom siv fais fab tso zis tawm?
Siv 2 {{{{m oscilloscope bandwidth li tus qauv txwv, lub voltage yog teeb tsa rau pk-pk (muaj txiaj ntsig zoo tau). Tshem tawm cov hlau clamp thiab av xaim rau ntawm osop lub suab nrov (vim tias lub kav hlau txais xov hluav taws xob (nws kuj tseem tuaj yeem siv lub ntsej muag hauv av, tab sis qhov yuam kev tsim nyog yuav tsum tau txiav txim siab). Parallel A 10UF Electrolytic Capacitor thiab ib tug 0.1uf ceramic Capacitor ntawm cov kev sojntsuam, thiab kuaj ntsuas tus oscilloscope zoo nkauj; Yog tias cov kev sojntsuam Oscilloscope tsis ncaj qha hu ncaj qha rau cov zis taw tes, nws yuav tsum ntsuas siv khub khub khub cable lossis 50 ω coaxial cables.
Cov zis ripple ntawm hloov hluav taws xob cov khoom siv feem ntau yog los ntawm tsib yam: Cov lus qhia tsawg-zaus Ripple; High zaus Riple; Hom suab nrov sib xws los ntawm cov kab mob cab; Ultra High zaus Roundonance nrov nrov tsim tawm thaum hloov cov txheej txheem ntawm cov khoom siv fais fab; Ripple suab los ntawm kaw-lub voj kev cai tswj.
Ripple yog ACT kev cuam tshuam teeb tsa lub teeb liab superimposed ntawm DC lub teeb liab thiab yog qhov tseem ceeb ntawm kev sim tshuaj. Tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob siv rau cov hom phiaj tshwj xeeb, xws li cov khoom siv hluav taws xob tshwj xeeb, Ripple yog ib qho ntawm lawv cov neeg tuag taus. Yog li, kev sim ntawm lub hwj chim ripple yog qhov tseem ceeb heev.
Muaj cov kwv yees ob txoj kev rau ntsuas hluav taws xob ripple: ib qho yog txoj kev ntsuas ntsuas teeb liab; Lwm lub moos yog qhov ntsuas teeb tsa teeb tsa tam sim no.
Feem ntau, rau qhov ntsuas hluav taws xob tas li lossis qhov chaw tam sim no uas muaj cov kev xav tau tsawg Txog qhov chaw tam sim no nrog cov kev xav tau loj, nws yog qhov zoo tshaj plaws los siv cov teeb tsa ntsuas ntsuas cov teeb liab tam sim no.
Kev ntsuas teeb liab riple kom raug rau siv tus oscilloscope los ntsuas cov piplex teeb liab teeb liab superimposed ntawm DC voltage teeb liab. Rau qhov chaw voltage tas li, kev sim tuaj yeem siv cov kev sojntsuam voltage los ntsuas qhov hluav taws xob cov teeb liab tawm mus rau lub nra. Rau kev sim cov chaw tam sim no tas li, feem ntau yog ua los ntawm kev siv cov kev soj ntsuam voltage ntawm ob qho kawg ntawm cov qauv resistor. Thaum lub sij hawm tag nrho cov txheej txheem xeem, teeb tsa ntawm oscilloscope yog tus yuam sij rau seb cov cim tseem ceeb tuaj yeem yog tus qauv.
