Qhov twg zoo dua, digital oscilloscope lossis analog oscilloscope?
Nrog rau kev txhim kho txuas ntxiv thiab kev nce qib ntawm cov cuab yeej siv hluav taws xob niaj hnub no, cov oscilloscopes digital thiab analogue oscilloscopes tau dhau los ua ib qho cuab yeej siv feem ntau rau kev ntsuas hluav taws xob. Qhov ob feem siv digital lossis analogue teeb liab tau los ntsuas cov teeb liab hluav taws xob, txhua tus muaj nws tus yam ntxwv thiab qhov zoo thiab qhov tsis zoo. Yog li qhov twg yog qhov zoo dua, digital oscilloscope lossis analogue oscilloscope? Cov hauv qab no yuav tham los ntawm ntau yam.
1. Txoj Cai
Cov oscilloscopes siv cov teeb liab ua cov thev naus laus zis kom tau txais thiab ua tiav cov teeb liab hluav taws xob, cov teeb liab tawm tswv yim hloov mus rau cov ntaub ntawv digital, tom qab ua cov digital thiab tom qab ntawd hloov mus rau analogue teeb liab tso tawm, thiab thaum kawg tso tawm ntawm qhov screen ntawm oscilloscope. Analogue oscilloscopes, ntawm qhov tod tes, amplify thiab lim cov tswv yim teeb liab ncaj qha, thiab tom qab ntawd tso tawm cov amplified waveform ntawm lub oscilloscope screen. Nws tuaj yeem pom tau tias cov oscilloscopes siv cov teeb liab ua cov hauv paus ntsiab lus, thaum analogue oscilloscopes siv analogue teeb liab ua cov qauv. Hauv qhov kev hwm no, cov oscilloscopes digital yog qib siab dua li analogue oscilloscopes.
2. Kev ua haujlwm
Cov oscilloscopes digital muaj ntau yam kev tshaj lij, xws li kev tsom xam spectrum, waveform capture, tsis siv neeg ntsuas, tsis siv neeg calibration, thiab lwm yam, tab sis kuj muaj qhov ntsuas siab dua thiab lub sij hawm teb sai dua. Analogue oscilloscopes, ntawm qhov tod tes, yog qhov yooj yim thiab tsuas yog ua tau yooj yim ntsuas thiab kev soj ntsuam. Los ntawm qhov no, cov oscilloscopes digital zoo dua li analogue oscilloscopes.
3. Qhov tseeb
Cov oscilloscopes siv cov teeb liab ua cov hauv paus ntsiab lus, tuaj yeem ntsuas qhov tseeb ntawm cov teeb liab hluav taws xob, kev ntsuas qhov tseeb tuaj yeem ncav cuag ntau tshaj kaum kaum qhov chaw, yog li qhov tseeb dua li analogue oscilloscopes. Nyob rau tib lub sijhawm, cov oscilloscopes digital kuj muaj kev daws teeb meem siab dua thiab tuaj yeem tso tawm sai dua thiab nyuaj waveforms. Analogue oscilloscopes siv analogue teeb liab ua cov hauv paus ntsiab lus, muaj cov teeb liab degradation, teeb liab attenuation thiab lwm yam teeb meem, thiab yog li ntawd tsis muaj peev xwm ua tiav qhov tseeb ntawm cov oscilloscopes. Los ntawm qhov no, qhov tseeb ntawm digital oscilloscopes kuj zoo dua li analogue oscilloscopes.
4. Teb ceev
Cov lus teb ceev ntawm cov oscilloscopes yog nrawm dua li ntawm analogue oscilloscopes, thiab cov ntaub ntawv tau txais thiab ua tiav tuaj yeem ua tiav nyob rau hauv ob peb nanoseconds, yog li nws yog qhov tsim nyog rau kev soj ntsuam cov teeb liab ceev thiab kev soj ntsuam. Ntawm qhov tod tes, analogue oscilloscopes muaj lub sijhawm teb qeeb dua thiab tsuas yog tsim nyog rau kev soj ntsuam thiab tshuaj xyuas cov teeb liab qis. Hauv qhov kev hwm no, cov lus teb ceev ntawm cov oscilloscopes yog qhov zoo dua li ntawm analogue oscilloscopes.
5. Tus nqi
Digital oscilloscopes kuj tseem kim, txij li ob peb puas mus rau ntau pua txhiab daus las. Analogue oscilloscopes, ntawm qhov tod tes, yog pheej yig dua li cov oscilloscopes, feem ntau raug nqi tsuas yog ob peb kaum mus rau pua pua nyiaj, ua rau lawv zoo tagnrho rau cov menyuam kawm ntawv thiab cov pib tshiab. Nws yog ib qho tseem ceeb heev uas yuav tau xaiv qhov oscilloscope los yuav raws li qhov xav tau tiag tiag thiab peev nyiaj txiag.
Txhawm rau ua kom tiav, cov oscilloscopes thiab analogue oscilloscopes muaj lawv tus kheej cov yam ntxwv thiab qhov zoo thiab qhov tsis zoo, thiab koj yuav tsum xaiv qhov oscilloscope los yuav raws li koj qhov kev xav tau tiag tiag thiab peev nyiaj txiag. Yog tias koj yuav tsum tau soj ntsuam thiab txheeb xyuas cov teeb liab hluav taws xob nrog kev ua haujlwm siab, kev kub ceev thiab cov waveforms nyuaj, nws raug nquahu kom xaiv cov oscilloscopes digital; Yog tias koj tsuas saib thiab txheeb xyuas cov cim hluav taws xob yooj yim lossis muaj peev txheej tsawg, nws raug nquahu kom xaiv analogue oscilloscopes.
