Oscilloscope siv _Oscilloscope siv txoj kev thiab cov tswv yim
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 cov txheej txheem kab rov tav thinnest ua ntej yuav 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. Brightness yog teem rau nruab nrab, tsom thiab pab tsom xam yog teem rau nruab nrab, ntsug input coupling yog teem rau "AC,,, ntsug voltage ntau yam xaiv yog teem rau 5mv / div, ntsug ua hauj lwm hom xaiv yog teem rau "CHl", ntsug rhiab heev fine-tuning calibration txoj hauj lwm yog teem rau "CAL, ntsug channel synchronization Qhov chaw xaiv yog teem rau nruab nrab txoj hauj lwm, ntsug txoj hauj lwm yog teem rau nruab nrab txoj hauj lwm, lub sij hawm scan A thiab B yog preset ua ke ntawm "{{4} }.5ms/div, A scan sij hawm zoo hloov kho yog teem rau calibration txoj hauj lwm "CAL", txoj kab rov tav yog teem rau nruab nrab txoj hauj lwm, scanning ua hauj lwm hom teeb "A", lub trigger synchronization hom yog teem rau "AUTO ", txoj kab nqes hloov yog teem rau "+", qhov kev sib txuas sib txuas tau teeb tsa rau "AC", thiab qhov kev xaiv qhov kev xaiv yog teem rau INT (2) Nias lub hwj huam hloov thiab lub teeb qhia lub zog yuav teeb. (3) Kho lub teeb tsom teeb pom kev zoo thiab lwm yam kev tswj cov pob khawm kom tau txais lub hauv paus nyias thiab ci ci. Kho lub hauv paus kom nws txoj hauj lwm nyob rau hauv nruab nrab ntawm qhov screen thiab yeej coincides nrog rau kab rov tav coordinate scale. (4) Kho qhov kev tswj hwm kev sib luag kom ua kom lub hauv paus sib luag mus rau kab rov tav kev tswj hwm.
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 lub qhov (socket), kov qhov ntsuas qhov ntsuas mus rau qhov ntsuas qhov ntsuas, thiab tom qab ntawd soj ntsuam cov 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. Phase sib txawv ntsuas Phase sib txawv: kab rov tav sib txawv tus nqi (degree) x kab rov tav 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
