Dual-trace oscilloscope ua hauj lwm hauv paus ntsiab lus Dual-trace oscilloscope lub ntsiab qhov chaw
Oscilloscopes yog siv los tso saib qhov hluav taws xob waveforms thiab lawv cov ntsiab lus tseem ceeb yog oscilloscope. Lub oscilloscope muaj ib rab phom hluav taws xob, Y-deflection phaj, X-deflection phaj, thiab lub vijtsam fluorescent, thiab siv lub tshuab hluav taws xob hloov mus sij hawm tig ob lub cim hluav taws xob los ntsuas, YCH1 thiab YCH2, mus rau Y-deflection. phaj. Vim qhov pom kev hysteresis, ob lub waveforms tuaj yeem pom ntawm lub vijtsam fluorescent.
Txoj Cai Ua Haujlwm ntawm Ob Chav Kab Oscilloscope
Cov phom electron yog rhuab los ntawm cov filament thiab emits electrons. Lub tsom electrode tsom cov electrons tawm los ntawm rab phom electron mus rau hauv lub teeb hluav taws xob zoo heev, uas ua rau cov duab waveform pom meej. Lub accelerating ncej muaj qhov zoo voltage kom nyiam cov khoom siv hluav taws xob los ntawm cov phom hluav taws xob kom txav mus los ntawm kev kub ceev; cov zaub muaj qhov zoo voltage kom nyiam electrons los tsoo cov zaub nto kom cov zaub nto coated nrog cov khoom fluorescent kom emit lub teeb. Vertical deflection phaj thiab kab rov tav deflection phaj nrog deflection voltage, lub polarity thiab amplitude ntawm deflection voltage los tswj txoj hauj lwm ntawm lub electron beam cuam tshuam rau ntawm cov zaub nto. Lub polarity thiab amplitude ntawm deflection voltage tswj txoj hauj lwm ntawm electron beam tsoo rau saum npoo ntawm cov zaub. Thaum lub deflection voltage ua raws li qhov kev hloov ntawm lub teeb liab input, lub electron beam tuaj yeem ua rau "kos" lub teeb liab waveform ntawm qhov screen. Dual trace oscilloscopes muaj ob lub tswv yim, tso cai rau ob lub teeb liab hluav taws xob sib txuas ua ke rau cov zaub. Nyob rau hauv lub oscilloscope, lub input teeb liab yuav amplified, kev siv ntawm hluav taws xob keyboards yuav ob lub input signals rotating hloov mus rau lub oscilloscope deflection phaj, thiaj li hais tias ob lub teeb liab tshwm nyob rau hauv lub screen ntawm oscilloscope tib lub sij hawm, kom yooj yim. kev soj ntsuam ntawm ob lub cim rau kev sib piv.
Qhov tseem ceeb ntawm dual-trace oscilloscope
Lub ntsiab tseem ceeb muaj xws li oscilloscope, lub amplifier, scanning thiab triggering system, uas yog ces hloov raws li cov khoom specifications teev nyob rau hauv cov khoom catalogue.
