Yuav siv cov oscilloscopes li cas thiab cov lus nug nquag nug
Yuav siv li cas oscilloscope
1. Tau txais cov hauv paus ntsiab lus: Thaum tus neeg teb xov tooj siv lub oscilloscope yam tsis muaj phau ntawv qhia, nws yuav tsum xub tau txais qhov zoo tshaj plaws kab rov tav lub hauv paus ua ntej siv qhov kev sojntsuam los ua lwm yam kev ntsuas. Cov txheej txheem tshwj xeeb yog raws li hauv qab no: (1) Preset cov keyboards thiab pob qhov rooj ntawm lub vaj huam sib luag. Teem lub brightness mus rau nruab nrab, lub tsom xam thiab pab tsom mus rau nruab nrab, ntsug input coupling rau "AC," lub ntsug voltage ntau yam xaiv rau "5mv / div", ntsug ua hauj lwm hom xaiv rau "CHl", ntsug rhiab heev. -tuning calibration txoj hauj lwm rau "CAL", Lub ntsug channel synchronization qhov chaw xaiv yog teem rau nruab nrab txoj hauj lwm, txoj hauj lwm ntsug yog teem rau nruab nrab txoj hauj lwm, lub sij hawm scan A thiab B yog preset ua ke ntawm "0. 5ms / div", lub sij hawm scan zoo yog teem rau calibration txoj hauj lwm "CAL", thiab txoj hauj lwm kab rov tav yog teem rau nruab nrab txoj hauj lwm, lub scanning ua hauj lwm hom yog teem rau "A", lub trigger synchronization hom yog teem rau "AUTO", txoj kab nqes hloov yog teem rau "+", qhov kev sib txuas ntawm qhov sib txuas yog teem rau "AC", thiab qhov kev xaiv qhov kev xaiv yog teem rau "INT". (2) Nias lub hwj chim hloov. Qhov taw qhia teeb yog qhib. (3) Kho qhov cuam tshuam cov pob qhov rooj xws li Kev tsom teeb ci kom tsim tau ib qho yooj yim thiab ci scanning hauv paus. Kho lub hauv paus kom nws txoj hauj lwm nyob rau hauv nruab nrab ntawm qhov screen yeej coincides nrog rau kab rov tav coordinate scale. (4) Kho qhov kev tswj hwm kev sib luag kom ua rau lub hauv paus Parallel mus rau txoj kab rov tav.
2. Cov teeb liab pom: Raws li ib txwm muaj, oscilloscope nws tus kheej muaj 0.5Vp-p tus qauv square yoj teeb liab tawm qhov chaw nres nkoj. Tom qab tau txais lub hauv paus, qhov kev sojntsuam tuaj yeem txuas rau ntawm no. Nyob rau lub sijhawm no, yuav tsum muaj cov xwm txheej square nthwv dej ntawm lub vijtsam. Kho qhov voltage. Qhov ntau thiab cheb lub sij hawm zoo knobs, lub amplitude thiab dav ntawm lub square yoj yuav tsum hloov. Qhov no txhais tau hais tias oscilloscope tau hloov kho thiab tuaj yeem muab tso rau hauv kev siv.
3. Ntsuas lub teeb liab: Txuas cov kab xeem mus rau CHl lossis CH2 input qhov (socket), kov lub ntsuas ntsuas mus rau qhov ntsuas ntsuas, thiab tom qab ntawd saib cov qauv waveform ntawm oscilloscope. Yog hais tias lub waveform amplitude loj dhau los yog me me, kho qhov voltage ntau qhov pob qhov rooj; Yog hais tias lub sij hawm waveform zaub tsis haum, kho lub scan ceev knob.
Txoj kev siv tshwj xeeb 1. AC ncov voltage ntsuas (1) Tau txais lub hauv paus. (2) Kho lub V / div pob qhov rooj kom lub waveform qhia 5div (piv txwv li 5 daim phiaj) nyob rau hauv txoj kab ntsug. (3) Kho "Ib theem pib" kom tau txais cov zaub ruaj khov. (4) Xam qhov siab tshaj voltage siv cov qauv hauv qab no. Voltage (pp): ntsug deflection amplitude/degree x (VOLTS/div)/hloov iav ncej x sojntsuam attenuation magnification. Piv txwv li: qhov ntsuas deflection ntawm lub ncov qaum teb mus rau lub ncov qis yog 5.6 degrees, lub VOLTS / dir hloov yog teem rau {{10}}.5, thiab x10 sojntsuam attenuation magnification yog siv, thiab cov ntaub ntawv yog hloov: Voltage 2 5. 6 X{31}}.5X10228V. 2. Kev ntsuas lub sij hawm nce lub sij hawm: kab rov tav nrug (degree) x lub sij hawm / degree (iav) / expansion coefficient. Piv txwv li: qhov kev ncua deb ntawm ob lub ntsiab lus ntawm lub waveform yog 5 degrees, lub sij hawm/degree theem yog 1Us, x10 expansion tsis nthuav (ie x1), tus nqi muab yog hloov los ntawm: nce lub sij hawm kuv faib; 5X1/1; 51xs ib. 3. Kev ntsuas qhov sib txawv Phase sib txawv: kab rov tav sib txawv tus nqi (degree) x kab rov tav nplai calibration tus nqi (degree/degree). Piv txwv li: kab rov tav sib txawv yog 0.6 degrees, thiab txhua qib yog calibrated rau 45 degrees. Hloov tus nqi muab rau hauv cov qauv: theem sib txawv: 0.6x45:27
1. Yuav ua li cas ntsuas DC voltage?
Teb: Ua ntej, koj yuav tsum tau teeb tsa lub coupling hom rau DC, kho cov iav ntsug kom tsim nyog tus nqi raws li qhov kwv yees, thiab tom qab ntawd sib piv cov kev hloov pauv ntawm cov kab offset thiab cov cim channel.
2. Cov neeg siv tau tshaj tawm tias qhov amplitude tshaj qhov screen ntau thaum ntsuas 220V lub zog hluav taws xob? Yuav ntsuas cov theem sib txawv ntawm peb-theem fais fab mov li cas?
Teb: Qhov siab tshaj plaws input peak-rau-peak voltage yog 400V. Raws li cov txiaj ntsig zoo ntawm kev hloov pauv hloov pauv-rau-nruab mis mis, 220V lub zog hluav taws xob ntau tshaj 400V ncov-rau-peak voltage, thiab qhov amplitude tshaj li qhov qub ntawm qhov screen. Thaum siv lub oscilloscope los ntsuas cov theem hloov ntawm peb-theem fais fab mov, koj tuaj yeem teeb tsa qhov chaw rau lub hauv paus, siv ib qho channel los ntsuas AB waveform ua ntej, tom qab ntawd khaws cia raws li kev siv waveform, thiab tom qab ntawd siv qhov kev sojntsuam. txuas BC. Lub sijhawm no, kev hloov pauv theem tuaj yeem ntsuas tau.
3. Dab tsi yog kev txwv tsis meej?
Teb: Tsis meej pem yog ib yam mob tshwm sim los ntawm qhov zaus uas tau sau los ntawm oscilloscope tau qis dua ob npaug ntawm qhov siab tshaj plaws ntawm lub teeb liab tiag tiag. Kev tawm tsam tsis meej pem yog tshwj xeeb tsim los tiv thaiv qhov tshwm sim ntawm kev tsis meej pem. Kev tsis sib haum xeeb tuaj yeem txheeb xyuas qhov ntau zaus ntawm lub teeb liab thiab sau cov teeb liab ntawm 2 npaug ntawm qhov siab tshaj plaws.
