Kev taw qhia txog oscilloscope ob-kab oscilloscope
Hauv cov txheej txheem ntawm kev siv tshuab hluav taws xob, feem ntau yuav tsum tau soj ntsuam cov txheej txheem ntawm ob (lossis ntau tshaj ob) cov cim hloov nrog lub sijhawm tib lub sijhawm. Thiab ua qhov kev ntsuam xyuas fais fab thiab kev sib piv ntawm cov cim sib txawv no. Txhawm rau kom ua tiav lub hom phiaj no, tib neeg siv ob txoj hauv qab no los nthuav tawm ntau lub waveforms tib lub sijhawm raws li kev siv cov qauv oscilloscope zoo tib yam: ib qho yog ob kab (lossis ntau kab) oscilloscope txoj kev; lwm qhov yog ob txoj kab (lossis Ntau kab) oscillometric txoj kev. Cov oscilloscopes tsim siv ob txoj kev no hu ua dual-line (los yog ntau kab) oscilloscopes thiab dual-trace (los yog ntau kab) oscilloscopes feem.
Ob-xaim (los yog ntau-xaim) oscilloscope yog siv los siv ob rab phom (los yog ntau rab phom) oscilloscope raj. Cov hauv qab no yog ib qho yooj yim piav qhia siv ob rab phom oscilloscope raj ua piv txwv. Ob rab phom oscilloscope muaj ob lub phom hluav taws xob ywj pheej uas tsim ob kab hluav taws xob. Kuj tseem muaj ob pawg ntawm kev ywj pheej deflection systems, uas txhua tus tswj lub nqaj ntawm electrons txav mus, nqis, sab laug thiab sab xis. Lub vijtsam fluorescent tau sib koom, yog li ob qhov sib txawv hluav taws xob teeb liab waveforms tuaj yeem tshwm sim ntawm qhov screen tib lub sijhawm, thiab ob kab oscilloscopes kuj tuaj yeem paub siv ib rab phom dual-kab oscilloscope raj. Hom oscilloscope no tsuas muaj ib rab phom electron xwb, uas tso siab rau cov electrodes tshwj xeeb los faib cov electrons rau hauv ob kab. Tom qab ntawd, ob pawg ntawm kev ywj pheej deflection systems nyob rau hauv lub raj tswj kev nce thiab nqis, sab laug thiab txoj cai txav ntawm ob lub teeb hluav taws xob raws li. Lub vijtsam fluorescent tau sib koom thiab tuaj yeem tso saib ob lub teeb liab sib txawv hluav taws xob sib txawv tib lub sijhawm. Vim yog cov txheej txheem tsim khoom siab thiab tus nqi siab ntawm ob-xaim oscilloscope raj, lawv cov ntawv thov tsis ntau heev.
