Cov muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb ntawm oscilloscope dynamic hluav taws xob ntsuas qhov system
Kev ntsuas hluav taws xob hluav taws xob yog qhov paub tab, feem ntau siv thiab tseem ceeb rau kev ntsuas tshuab. Nws yog ze ze rau cov teeb meem loj xws li kev siv hluav taws xob, cov txiaj ntsig kev lag luam thiab kev tiv thaiv ib puag ncig. Txawm li cas los xij, cov khoom kuaj ntawm qhov feem ntau hu ua "kev ntsuas hluav taws xob" feem ntau yog DC lossis lub zog hluav taws xob ntau zaus hluav taws xob. Lawv txhua tus coj tus cwj pwm tsis tu ncua. Nws tus nqi tsis hloov nrog lub sijhawm lossis hloov maj mam lossis tsis tu ncua. Feem ntau hais lus, ntau yam khoom siv hluav taws xob ntsuas hluav taws xob tuaj yeem siv los ntsuas qee qhov ntsuas qhov tseem ceeb raws li cov qauv kev lag luam. Txawm li cas los xij, nrog kev txhim kho ntawm cov ntawv thov kev tshawb fawb thiab kev siv tshuab thev naus laus zis niaj hnub no, hauv ntau qhov kev sim, cov txheej txheem kev lag luam thiab cov khoom lag luam, kev hloov pauv ntawm lub zog tsis yog cov txheej txheem tsis tu ncua, tab sis tshwm sim tam sim ntawd, random thiab instantaneous hloov nyob rau hauv lub sij hawm. yog tus txheej txheem dynamic time domain. Muaj ntau yam piv txwv zoo li no hauv kev xyaum. Piv txwv li, nyob rau hauv lub automated tswj ntawm industrial cov txheej txheem, kev khiav hauj lwm tej yam kev mob ntawm motors yog ua complex, uas yog manifested los ntawm ib tug loj nce nyob rau hauv cov kev hloov pauv ntawm lub cev muaj zog ua hauj lwm. Ntawd yog, txhawm rau txhawm rau ua tiav cov lus qhia kev tswj hwm, lub cev muaj zog yuav tsum nquag pib, nres, hloov ceev, rov qab kev taw qhia, thauj khoom, tshem tawm, thiab lwm yam. Lwm qhov piv txwv yog kev sau thiab tso tawm ntawm lub zog hauv cov khoom siv hluav taws xob (capacitors, inductors, roj teeb, thiab lwm yam), uas feem ntau tshwm sim raws li ib qho kev hloov pauv hloov sijhawm. Lwm qhov piv txwv yog lub zog hluav taws xob ntawm lub tshuab hluav taws xob, uas yog lub sijhawm ua haujlwm nrog lub voj voog me me, lub plawv dhia ceev heev, thiab muaj zog electromagnetic cuam tshuam. Txawm hais tias qhov kev sim ntsuas ntawm lub zog ruaj khov thiab lub zog tsis muaj zog yog tib yam, qhov hluav taws xob thiab qhov tam sim no tau muab sib npaug ntawm lub sijhawm sib txuas kom tau txais lub zog thiab tom qab ntawd sib xyaw ua ke dhau sijhawm, qhov nyuaj ntawm kev sim tshuab thiab cov khoom siv nyuaj heev. txawv. Lub tom kawg xav tau qhov kev sim ntsuas kom muaj bandwidth txaus, zoo dynamic teb thiab muaj zog tiv thaiv kev cuam tshuam. Nyob rau tib lub sijhawm, cov ntaub ntawv raug ntes yuav tsum tau muab khaws cia rau hauv lub sijhawm, thiab tom qab ntawd tshuaj xyuas, ua tiav, thiab tau txais raws li lub sijhawm ua haujlwm waveforms ntawm voltage, tam sim no, lub zog, thiab lub zog, tsis yog qhov tseem ceeb ntawm qee lub sijhawm. Txhawm rau ua tiav cov haujlwm ntsuas saum toj no, tam sim no tsis muaj cov khoom siv hluav taws xob npaj ua kom muaj zog los xaiv los ntawm, thiab koj yuav tsum tsim koj tus kheej qhov kev sim. Ntawm ntau txoj hauv kev, cov kev daws teeb meem yog: qhov hluav taws xob thiab kev sojntsuam tam sim no + desktop ntse oscilloscope + khoos phis tawj + daim ntawv thov kev pabcuam. Ntawm lawv, kev xaiv kom raug ntawm oscilloscope yog qhov tseem ceeb.
Kuaj qhov system muaj pes tsawg leeg thiab cov yam ntxwv tseem ceeb
Lub zog ntsuas hluav taws xob ua haujlwm raws li TDS1000/2000/3000B series oscilloscopes feem ntau muaj cov khoom siv hluav taws xob thiab tam sim no, TDS series oscilloscopes, daim ntawv thov software, khoos phis tawj thiab khoom siv peripheral.
Tam sim no coj cov roj av cav hluav taws xob ntsuas hluav taws xob ua piv txwv los piav qhia txog cov txheej txheem kev ua haujlwm ntawm qhov kev sim: ua ntej, qhov ntsuas hluav taws xob high-voltage attenuates pulse high voltage tso zis los ntawm cov khoom siv hluav taws xob thiab xa mus rau Y input channel ntawm TDS. series oscilloscope, thaum lub sij hawm soj ntsuam tam sim no attenuates lub mem tes tso zis los ntawm lub ignition ntaus ntawv. Qhov me me tam sim no hloov mus rau hauv qhov sib txuam me me mem tes voltage thiab cov tswv yim rau lwm Y input channel ntawm TDS series oscilloscope. Tom qab ntawd kho ntau yam kev ua haujlwm tsis zoo ntawm oscilloscope, ntes qhov hluav taws xob thiab lub sijhawm tam sim no lub sijhawm ua haujlwm waveforms raws sijhawm thiab raug, thiab khaws cia rau hauv cov ntaub ntawv siv cim xeeb. Thaum kawg, nrog kev pab ntawm daim ntawv thov kev soj ntsuam software, cov ntaub ntawv ntes tau los ntawm oscilloscope yog xa mus rau lub computer thiab ua tiav kom tau txais cov ntaub ntawv hais txog lub zog thiab lub sij hawm sau waveform daim duab. Yog tias tsim nyog, cov ntaub ntawv yuav tsum tau muab tso rau hauv daim ntawv nyuaj lossis xa tawm hauv lub network.
