Ungayibala Kanjani Imvamisa evela ku-Oscilloscope?

Ngiyakuthanda ukudala okuqukethwe kwamahhala okugcwele izeluleko zabafundi bami, wena. Angilwamukeli uxhaso olukhokhelwayo, umbono wami owami, kepha uma uthola izincomo zami zilusizo futhi ugcina uthenga okuthile okuthandayo ngesinye sezixhumanisi zami, bengingathola ikhomishini ngaphandle kwezindleko ezengeziwe kuwe.

Ama-Oscilloscopes angalinganisa futhi abonise amandla we-voltage ngokushesha kodwa akhumbule ukuthi i oscilloscope kanye ne-multimeter ecacile akuyona into efanayo. Siqukethe screen ukuthi unamagrafu emise imigqa mpo futhi enezingqimba. I-oscilloscope ilinganisa i-voltage bese iyakha njenge-voltage kuqhathaniswa negrafu yesikhathi esibukweni. Imvamisa ayibonisi imvamisa ngqo kepha singathola ipharamitha ehlobene kakhulu kusuka kugrafu. Ukusuka lapho singabala imvamisa. Amanye ama-oscilloscopes akamuva kulezi zinsuku angakwazi ukubala ngokuzenzakalela imvamisa kepha lapha sizogxila ekutheni singazibala kanjani thina.

Izilawuli Nokushintsha ku-Oscilloscope

Ukubala imvamisa, sidinga ukuyixhuma ocingweni olunephenyo. Ngemuva kokuxhuma, izokhombisa igagasi le-sine elingaguqulwa nezilawuli nokushintsha ku-oscilloscope. Ngakho-ke kubalulekile ukwazi ngalezi zinguquko zokulawula.

Izilawuli-kanye-nama-switch-on-the-Oscilloscope

Hlolisisa Isiteshi Okusemqoka, uzoba nendawo yokuxhuma uphenyo lwakho ku-oscilloscope. Ngokuya ngohlobo lwedivayisi oyisebenzisayo kungaba nesiteshi esisodwa noma ngaphezulu kwesisodwa. Inkinobho Yesikhundla Kukhona i-knob yokuma enezingqimba futhi emile ku-oscilloscope. Lapho kukhombisa igagasi le-sine akuhlali kusenkabeni njalo. Ungazungezisa isibambo sokuma mpo ukwenza ifomu lokuphakama libe maphakathi kwesikrini. Ngendlela efanayo, kwesinye isikhathi igagasi lithatha kuphela ingxenye yesikrini bese sonke isibuko sihlala singenalutho. Ungazungezisa isibambo sesimo esivundlile ukuze wenze indawo evundlile yegagasi ibe ngcono futhi ugcwalise isikrini. I-Volt / div ne-Time / div Lezi zinkinobho ezimbili zikuvumela ukuthi ushintshe inani ngokuhlukaniswa ngakunye kwegrafu. Ku-oscilloscope, i-voltage ikhonjiswa ku-Y-axis futhi isikhathi sikhonjiswa ku-X-axis. Vula izinkinobho ze-volt / div kanye nesikhathi / div ukuze ulungise inani olifunayo ngokuhlukaniswa ngakunye ukuze uboniswe kugrafu. Lokhu kuzokusiza nokuthi uthole isithombe esingcono segrafu. Ukubangela Ukulawula I-oscilloscope ayiniki njalo igrafu ezinzile. Kwesinye isikhathi kungaphanjaniswa kwezinye izindawo. Lapha kufika ukubaluleka kwe- ukuqala kwe-oscilloscope. Isilawuli se-Trigger sikuvumela ukuthi uthole igrafu ehlanzekile esibukweni. Kuboniswa njengonxantathu ophuzi ohlangothini lwesokunene sesikrini sakho.

Ukulungisa i-Oscillosocpe Graph nokubala imvamisa

Imvamisa yinombolo ekhombisa ukuthi igagasi liqeda kangaki umjikelezo walo njalo ngomzuzwana. Ku-oscilloscope, awukwazi ukukala imvamisa. Kepha ungalinganisa isikhathi. Isikhathi yisikhathi esithathayo ukwakha umjikelezo ogcwele amagagasi. Lokhu kungasetshenziswa ukukala imvamisa. Nakhu ukuthi uzokwenza kanjani.

Ukuxhuma i-Probe

Okokuqala, xhuma uhlangothi olulodwa lwesheke esiteshini se-oscilloscope probe nolunye uhlangothi ocingweni ofuna ukululinganisa. Qiniseka ukuthi ucingo lwakho aludabuki noma kungenjalo kuzodala isekhethi elifushane elingaba yingozi.

Kusetshenziswa Izinduku Zokuma

Ukubeka izinto kubaluleke kakhulu maqondana nemvamisa. Ukuqaphela ukunqanyulwa komjikelezo wamagagasi ukhiye lapha.

Isikhundla esivundlile Ngemuva kokuxhuma ucingo ku-oscilloscope, izonikeza ukufundwa kwe-sine wave. Leli gagasi alihlali liphakathi noma lithatha isikrini esigcwele. Jika isibambo sokuma enezingqimba ngokwewashi uma ingathathi isikrini esigcwele. Yenze ibe ngewashi uma uzizwa sengathi ithatha isikhala esiningi esikrinini. Isikhundla Esiqondile Manje njengoba igagasi lakho le-sine selimboze sonke isikrini, kufanele usenze sigxile. Uma igagasi lingasohlangothini olungenhla lwesikrini vula i-knob ngokwewashi ukuyiletha phansi. Uma ingezansi kwesikrini sakho bese uyijikeleza ngokungafani newashi.

Isebenzisa i-Trigger

I-Trigger switch ingaba yisibambo noma iswishi. Uzobona unxantathu omncane ophuzi ngakwesokudla kwesikrini sakho. Lelo yizinga le-trigger. Lungisa leli zinga le-trigger uma igagasi lakho elibonisiwe limile noma lingacaci.

Usebenzisa i-Voltage / div ne-Time / div

Ukuzungezisa lezi zinkinobho ezimbili kuzoholela kuzinguquko kusibalo sakho. Akunandaba ukuthi amasethingi lawa ayiziphi izilungiselelo, umphumela uzofana. Ukubalwa kuphela okuzohluka. Amajazi we-Voltage / div ajikelezayo azokwenza igrafu yakho ibheke phezulu noma ibe mfushane futhi ijikeleze isikhathi se-Time / div knob sizokwenza igrafu yakho ibe yinde noma ibe mfushane ngokuvundlile. Ukuze kube lula sebenzisa i-1 volt / div no-1 isikhathi / div inqobo nje uma ubona umjikelezo ogcwele wegagasi. Uma ungakwazi ukubona umjikelezo ogcwele wamaza kulezi zilungiselelo ungakushintsha ngokuya ngesidingo sakho bese usebenzisa lawo masethingi ekubaleni kwakho.

Isikhathi sokulinganisa nokubala imvamisa

Ake sithi ngisebenzise ama-volts ama-0.5 ku-volt / div okusho ukuthi isigaba ngasinye simele .5 voltages. Futhi 2ms ngesikhathi / div okusho ukuthi isikwele ngasinye ngama-millisecond ama-2. Manje uma ngifuna ukubala isikhathi kuzofanela ngibheke ukuthi zingaki izigaba noma izikwele ezithatha ngokuvundlile ukuze kwenziwe umjikelezo ogcwele wamagagasi.

Ukulinganisa-Isikhathi-nokubala-Imvamisa

Isikhathi sokubala

Ithi ngithole ukuthi kuthatha ukwahlukaniswa okungu-9 ukwakha umjikelezo ogcwele. Lapho-ke inkathi ukuphindaphindwa kwezilungiselelo zesikhathi / i-div kanye nenombolo yezigaba. Ngakho-ke kuleli cala 2ms * 9 = 0.0018 imizuzwana.

Kubalwa Imvamisa

Manje, ngokusho kwefomula, F = 1 / T. Lapha u-F imvamisa no-T yisikhathi. Ngakho-ke imvamisa, kuleli cala, kuzoba ngu-F = 1 / .0018 = 555 Hz.

Futhi ungabala ezinye izinto ngokusebenzisa ifomula F = C / λ, lapho i-λ ubude bomkhawulo kanye no-C kuyisivinini segagasi okuyisivinini sokukhanya.

Isiphetho

I-oscilloscope iyithuluzi elibaluleke kakhulu emkhakheni kagesi. I-oscilloscope isetshenziselwa ukubuka izinguquko ezisheshayo ku-voltage ngokuhamba kwesikhathi. Kuyinto i-multimeter angikwazi ukwenza. Lapho i-multimeter ikubonisa kuphela i-voltage, i-oscilloscope ingasetshenziselwa kwenze igrafu. Kusuka kugrafu, ungalinganisa ngaphezu kwamandla kagesi, njengesikhathi, imvamisa, nobude bamaza. Ngakho-ke kubalulekile ukufunda ngemisebenzi ye-oscilloscope.
