Oscilloscopes raug cais raws li cov cim sib txawv

Analogue oscilloscope siv ib qho analog circuit (oscilloscope raj, uas yog raws li ib rab phom electron). Cov phom hluav taws xob tso hluav taws xob mus rau qhov screen, uas tau tsom mus tsim ib lub teeb hluav taws xob thiab ntaus lub vijtsam. Sab hauv ntawm lub vijtsam yog coated nrog cov khoom siv fluorescent, kom cov ntsiab lus ntaus los ntawm lub teeb hluav taws xob emit lub teeb.
Cov oscilloscope digital yog qhov ua tau zoo oscilloscope uas tsim los ntawm ntau cov thev naus laus zis xws li kev tau txais cov ntaub ntawv, A / D hloov dua siab tshiab, thiab software programming. Hom kev ua haujlwm ntawm digital oscilloscope yog hloov pauv qhov ntsuas hluav taws xob rau hauv cov ntaub ntawv digital los ntawm kev hloov pauv analog (ADC). Lub oscilloscope digital captures cov qauv ntawm cov qauv ntawm lub waveform thiab khaws cia kom txog thaum nws txiav txim siab seb cov qauv tsim nyog tuaj yeem piav qhia txog lub waveform. Tom qab ntawd, digital oscilloscope reconstructs lub waveform. Cov oscilloscopes tuaj yeem muab faib ua digital storage oscilloscopes (DSOs), digital fluorescence oscilloscopes (DPOs), thiab sampling oscilloscopes.
Txhawm rau txhim kho qhov bandwidth ntawm analog oscilloscopes, nws yog ib qho tsim nyog yuav tsum ua kom tiav cov oscilloscope raj, ntsug amplification, thiab kab rov tav scanning. Txhawm rau txhim kho qhov bandwidth ntawm lub oscilloscope digital, nws tsuas yog tsim nyog los txhim kho kev ua haujlwm ntawm lub hauv ntej-kawg A / D converter, thiab tsis muaj cov cai tshwj xeeb rau oscilloscope raj thiab scanning circuit. Tsis tas li ntawd, cov oscilloscope cov raj tuaj yeem siv tag nrho lub cim xeeb, khaws cia, thiab kev ua haujlwm, nrog rau ntau yam ua rau muaj kev cuam tshuam thiab ua kom muaj peev xwm ua tau zoo. Hauv xyoo 1980, cov oscilloscopes digital tau tshwm sim nrog ntau qhov kev ua tiav, thiab muaj peev xwm hloov pauv cov analog oscilloscopes thoob plaws. Analog oscilloscopes yeej tau tawm ntawm lub hauv ntej mus rau tom qab.
