Oscilloscope fais fab mov Circuit Court
Lub zog hluav taws xob hluav taws xob muab cov hluav taws xob tsis zoo thiab cov hluav taws xob tsis zoo uas yuav tsum tau ua los ntawm txoj kab ntsug thiab kab rov tav amplification circuits, scanning thiab synchronization circuits, thiab oscilloscope raj thiab tswj circuits.
Nws tuaj yeem pom los ntawm daim duab thaiv kev ua haujlwm ntawm oscilloscope uas ntsuas lub teeb liab voltage ntxiv rau Y-axis input kawg ntawm oscilloscope, thiab ntxiv rau cov phaj ntsug deflection ntawm lub oscilloscope raj los ntawm ntsug amplification Circuit Court. Txawm hais tias kab rov tav deflection voltage ntawm oscilloscope siv sawtooth voltage nyob rau hauv feem ntau (rau kev soj ntsuam waveforms), lwm yam kev siv voltages yog siv qee zaum (rau ntsuas zaus, theem sib txawv, thiab lwm yam), yog li ntawm cov tswv yim kawg ntawm kab rov tav amplification Circuit Court muaj. kab rov tav xaiv hloov mus xaiv cov sawtooth yoj voltage nyob rau hauv lub oscilloscope raws li xav tau, los yog siv lwm yam voltages thov mus rau lub X-axis input kawg raws li cov kab rov tav deflection voltage.
Tsis tas li ntawd, txhawm rau ua kom cov duab tso tawm ntawm lub vijtsam fluorescent ruaj khov, qhov zaus ntawm lub sawtooth voltage teeb liab thiab qhov zaus ntawm cov teeb liab ntsuas yuav tsum tau synchronized. Nyob rau hauv txoj kev no, tsis yog tsuas yog qhov zaus ntawm sawtooth yoj voltage yuav tsum tau hloov kho tas li, tab sis kuj tseem muaj lub teeb liab synchronization yuav tsum tau nkag mus rau hauv Circuit Court uas tsim cov sawtooth yoj. Nyob rau hauv txoj kev no, rau ib qho yooj yim oscilloscope (xws li domestic SB10 oscilloscope) uas tsuas tuaj yeem tsim ib lub xeev ntawm kev soj ntsuam tas li (uas yog, tsim ib qho rov tshwm sim thiab tsis tu ncua sawtooth yoj), nws yog ib qho tsim nyog yuav tsum tau nkag mus rau qhov zaus cuam tshuam nrog cov zaus ntawm qhov pom teeb liab ntawm nws lub voj voog scanning. Synchronization teeb liab kom muaj qhov oscillation zaus ntawm sawtooth yoj. Rau oscilloscopes nrog ib tug tos scan muaj nuj nqi (uas yog, tsis muaj sawtooth yoj yog generated nyob rau tib lub sij hawm, thiab ib tug sawtooth nthwv dej yog generated thaum lub ntsuas teeb liab los txog, thiab ib tug scan yog ua) (xws li domestic ST-16 oscilloscope , Sr {-8 Dual-las otcilloscope engicter, yog li ntawd tias lub teeb liab uas sib koom ua ke nrog lub teeb liab raws li kev sim. Nyob rau hauv kev txiav txim hloov mus rau ntau yam kev xav tau, lub teeb liab synchronization (los yog txhais tes) tuaj yeem dhau los ntawm kev sib txuas lossis ua kom lub teeb liab xaiv hloov Kev xaiv, feem ntau muaj peb qhov chaw: ① Cov teeb liab ntsuas tau qhia los ntawm lub voj voog ntsug amplification raws li synchronization (los yog ua rau. ) teeb liab no hu ua "internal synchronization" (los yog "internal trigger") teeb liab; sab nraud trigger") teeb liab. Cov teeb liab no ntxiv rau sab nraud synchronization (los yog lwm qhov ua rau sab nraud) input davhlau ya nyob twg; ③ Qee cov oscilloscopes kuj muaj qhov hloov pauv ntawm kev xaiv lub teeb liab synchronization. Lub iav "lub zog synchronization" yog 220V, 50Hz fais fab mov voltage uas tau nqis los ntawm theem nrab ntawm lub transformer raws li lub teeb liab synchronization.
