Ndimakonda kupanga zinthu zaulere zodzaza ndi malingaliro kwa owerenga anga, inunso. Sindimavomereza ndalama zolipiridwa, malingaliro anga ndi anga, koma mukawona malingaliro anga akuthandizani ndipo mumatha kugula china chake chomwe mumakonda kudzera paulalo mwanga, nditha kupeza ntchito popanda mtengo wowonjezera kwa inu. Dziwani zambiri
Oscilloscopes ndi olowa m'malo mwachindunji ma multimeter. Zomwe multimeter ingachite, ma oscilloscopes amatha kuchita bwino. Ndipo pakuwonjezeka kwa magwiridwe antchito, kugwiritsa ntchito oscilloscope kumakhala kovuta kwambiri kuposa ma multimeter, kapena zida zilizonse zoyezera zamagetsi. Koma, si sayansi ya rocket. Apa tikambirana zoyambira zomwe muyenera kudziwa mukamagwira ntchito ndi oscilloscope. Tidzafotokoza zochepa zomwe muyenera kudziwa kuti mugwire ntchito ndi ma oscilloscopes.
Mu positi iyi tikambirana:
Mbali Zofunika za Oscilloscope
Tisanadumphe mu phunziroli, pali zinthu zingapo zomwe muyenera kuchita kudziwa za oscilloscope. Popeza ndi makina ovuta, ali ndi ziboda zambiri, mabatani chifukwa cha ntchito yake yonse. Koma Hei, simuyenera kudziwa za aliyense wa iwo. Tikambirana mbali zofunika kwambiri za kuchuluka komwe muyenera kudziwa musanapite.Ndimayeso
Oscilloscope ndi yabwino ngati mutha kuyilumikiza ndi siginecha, ndipo pazifukwa izi mukufunikira zofufuza. Ma probes ndi zida zolowetsa kamodzi zomwe zimatumiza chizindikiro kuchokera kudera lanu kupita komwe kuli. Ma probe odziwika amakhala ndi nsonga yakuthwa ndi waya pansi. Ma probe ambiri amatha kutsitsa chizindikirocho mpaka kakhumi kuposa chizindikiro choyambirira kuti chiwoneke bwino.Kusankhidwa Kwa Channel
Ma oscilloscopes abwino kwambiri ali ndi njira ziwiri kapena zingapo. Pali batani lodzipatulira pambali pa doko lililonse kuti musankhe njirayo. Mukasankha, mutha kuwona zotuluka panjirayo. Mutha kuwona zotulutsa ziwiri kapena zingapo nthawi imodzi ngati musankha njira zingapo nthawi imodzi. Zachidziwikire, payenera kukhala zolowetsa ma sign pa doko la mayendedwe.Choyambitsa
Kuwongolera kwa trigger pa oscilloscope kumakhazikitsa pomwe jambulani pa mawonekedwe amayambira. M'mawu osavuta, poyambitsa mu oscilloscope imakhazikika pazotulutsa zomwe tikuwona pachiwonetsero. Pa analogi oscilloscopes, kokha pamene a mlingo wina wamagetsi anali atafikiridwa ndi mawonekedwe a mafunde angayambike. Izi zitha kupangitsa kuti kusanthula kwa ma waveform kuyambike nthawi imodzi pamayendedwe aliwonse, ndikupangitsa kuti mawonekedwe awonekedwe okhazikika.Kupindula Kwambiri
Kuwongolera uku pa oscilloscope kumasintha kupindula kwa amplifier yomwe imayendetsa kukula kwa siginecha mu axis ofukula. Imayendetsedwa ndi mfundo yozungulira yokhala ndi milingo yosiyanasiyana yolembedwapo. Mukasankha malire apansi, zotsatira zake zidzakhala zazing'ono pazitsulo zolunjika. Mukawonjezera mulingo, zotulukazo zidzalowetsedwa ndikukhala zosavuta kuziwona.Ground Line
Izi zimatsimikizira malo a olamulira opingasa. Mukhoza kusankha malo ake kuti muwone chizindikiro pa malo aliwonse awonetsero. Izi ndi zofunika kuyeza matalikidwe mulingo wa chizindikiro chanu.Nthawi
Imayendetsa liwiro lomwe chophimba chimafufuzidwa. Kuchokera apa, nthawi ya waveform imatha kuwerengedwa. Ngati kuzungulira kwathunthu kwa mawonekedwe a waveform mpaka ma 10 ma microseconds kuti amalize, izi zikutanthauza kuti nthawi yake ndi 10 microseconds, ndipo ma frequencywo ndi ofanana ndi nthawiyo, mwachitsanzo 1 / 10 microseconds = 100 kHz.Gwirani
Izi zimagwiritsidwa ntchito kusunga chizindikiro kuti chisasinthe pakapita nthawi. Izi zimathandiza kuwona chizindikiro chosuntha mwachangu mosavuta.Kuwala & Kuthamanga Kwambiri
Iwo amachita zimene amanena. Pali ziboda ziwiri zolumikizirana paliponse zomwe zimakupatsani mwayi wowongolera kuwala kwa chinsalu ndikusintha kulimba kwa siginecha yomwe mukuwona pachiwonetsero.Kugwira ntchito ndi Oscilloscope
Tsopano, pambuyo pa zokambirana zonse zoyambira, tiyeni tiyatse kukula ndikuyamba zochitazo. Osathamanga, tipita pang'onopang'ono:- Lumikizani chord ndi kuyatsa kukula kukanikiza batani la / kuzimitsa. Ambiri mwa oscilloscope amakono ali nawo. Zotha ntchito zimayatsa pongolumikiza.
- Sankhani tchanelo chomwe mungagwiritse ntchito ndikuzimitsa ena. Ngati mukufuna tchanelo choposa chimodzi, sankhani ziwiri ndikuzimitsa zina zonse monga kale. Sinthani mlingo wapansi kulikonse kumene mukufuna ndikukumbukira mlingo.
- Lumikizani kafukufukuyo ndikukhazikitsa mulingo wochepetsera. Kuchepetsa kosavuta kwambiri ndi 10X. Koma mutha kusankha nthawi zonse malinga ndi zomwe mukufuna komanso mtundu wa chizindikiro.
- Tsopano muyenera calibrate kafukufuku. Nthawi zambiri mumangolumikiza kafukufuku wa oscilloscope ndikuyamba kuyeza. Koma ma probe a oscilloscope amayenera kuyesedwa asanazengedwe kuti atsimikizire kuti yankho lawo ndi lathyathyathya.
- Mukamaliza kukonza, gwirani nsonga yolunjika ya probe mu terminal yabwino ya dera lanu ndikutsitsa poyambira. Ngati zonse zikuyenda bwino ndipo dera likugwira ntchito, mudzawona chizindikiro pazenera.
- Tsopano, nthawi zina simudzawona chizindikiro chabwino nthawi yomweyo. Ndiye muyenera kuyambitsa linanena bungwe ndi choyambitsa mfundo.
- Mutha kuwona zotuluka momwe mukufunira posintha ma voliyumu pagawo lililonse ndikusintha kosintha pafupipafupi. Amawongolera kupindula koyima komanso nthawi yoyambira.
- Kuti muwone zambiri palimodzi, gwirizanitsani kafukufuku wina ndikusunga yoyamba yolumikizana. Tsopano sankhani njira ziwiri nthawi imodzi. Ndi zimenezotu.
Kutsiliza
Miyezo yochepa ikapangidwa, zimakhala zosavuta kugwiritsa ntchito oscilloscope. Popeza ma oscilloscope ndi chimodzi mwa zida zofunika kwambiri, ndikofunikira kuti aliyense amene ali ndi zida zamagetsi adziwe momwe angagwiritsire ntchito chipangizochi komanso momwe angagwiritsire ntchito bwino.
