Uwabala njani amaRhoqo kwi-Oscilloscope?

Ndiyakuthanda ukudala umxholo okhululekileyo ogcwele iingcebiso kubafundi bam, wena. Andilwamkeli uxhaso oluhlawulelweyo, uluvo lwam lolwam, kodwa ukuba ufumanisa ukuba izindululo zam ziluncedo kwaye ugqibela ngokuthenga into oyithandayo ngenye yeekhonkco zam, ndingafumana ikhomishini ngaphandle kwendleko ezongezelelweyo kuwe. Funda nzulu

Ii-Oscilloscopes zinokulinganisa kwaye zibonise amandla ombane ngokukhawuleza kodwa gcinani engqondweni ukuba oscilloscope kunye nemultimeter yemizobo ayisiyonto inye. Inesikrini esinegrafu emile nkqo kunye nemigca ethe tyaba. I-oscilloscope ilinganisa ivolthi kwaye iyenze njengevolthi ngokuchasene nexesha kwigrafu kwiscreen. Ihlala ingabonisi imvamisa ngokuthe ngqo kodwa sinokufumana ipharamitha enxulumene ngokusondeleyo kwigrafu. Ukusuka apho singabala ukubakho kwamaxesha. Ezinye zee-oscilloscopes zamva nje zinokubala ngokuzenzekelayo isantya kodwa apha siza kugxila kwindlela yokuzibala ngokwethu.

Ulawulo kunye nokuTshintsha kwi-Oscilloscope

Ukubala amaza, kufuneka siqhagamshele kwintambo ene-probe. Emva kokudibanisa, iya kubonisa i-sine wave enokuhlengahlengiswa kunye nolawulo kunye nokutshintsha kwi-oscilloscope. Ke kubalulekile ukuba wazi malunga nolu tshintsho lolawulo.

Ulawulo-kunye-noTshintsho kwi-Oscilloscope

Phanda iTshaneli Kumgca osezantsi, uya kuba nendawo yokudibanisa iprobe yakho kwi-oscilloscope. Kuxhomekeka kuhlobo lwesixhobo osisebenzisayo kunokubakho ishaneli esinye okanye ngaphezulu kwesinye. Indawo yokuQhobosha Kukho indawo ethe tyaba kunye ethe nkqo kwi-oscilloscope. Xa ibonisa i-sine wave akusoloko kusembindini. Ungajikeleza indawo yokuma nkqo ukwenza umda wamaza embindini wesikrini. Ngendlela efanayo, ngamanye amaxesha umtshangatshangiso uthatha kuphela isahlulo sescreen kwaye sonke iscreen sihlala singenanto. Ungayijikeleza i-knob yemeko ethe tyaba ukwenza indawo ethe tyaba yomtshangatshangiso ibengcono kwaye ugcwalise isikrini. Volt / div kunye nexesha / div Ezi zinqhina zimbini zikuvumela ukuba utshintshe ixabiso ngokwahlulahlula igrafu. Kwi-oscilloscope, umbane uboniswa kwi-Y-axis kwaye ixesha liyaboniswa kwi-X-axis. Jika i-volt / div kunye nexesha / ii-knobs zokuhlengahlengisa ixabiso olifunayo kwicandelo ngalinye ukubonisa kwigrafu. Oku kuya kukunceda ufumane umfanekiso ongcono wegrafu. Ulawulo lokuchukumisa I-oscilloscope ayisoloko inika igrafu ezinzileyo. Ngamanye amaxesha inokugqwethwa kwezinye iindawo. Nanku kuza ukubaluleka ukubangela i-oscilloscope. Ulawulo lokucutha likuvumela ukuba ufumane igrafu ecocekileyo kwiscreen. Kuboniswa njengonxantathu omthubi kwicala lasekunene lesikrini sakho.

Ukulungiswa kweGrafu ye-Oscillosocpe kunye nokuBala amaRhoqo

Ukuphindaphindwa linani elibonisa ukuba mangaphi amaxesha amaza agqibezela umjikelo wawo kwimizuzwana yonke. Kwi-oscilloscope, awunakulinganisa ubude. Kodwa ungalinganisa ixesha. Ixesha lixesha elithathayo ukwenza umjikelo ogcweleyo wamaza. Oku kunokusetyenziselwa ukulinganisa ubungakanani. Nantsi indlela oya kuyenza ngayo.

Ukulungisa-i-Oscillosocpe-Igrafu-kunye nokuBala-ukuRhoqo

Ukudibanisa iProbe

Okokuqala, qhagamshela icala elinye lesiphumo kwisitishi se-oscilloscope probe kunye nelinye icala ocingweni ofuna ukulinganisa. Qiniseka ukuba ucingo lwakho aludilwanga okanye kungenjalo luza kubangela isekethe emfutshane enokuba yingozi.

Sebenzisa iiNdawo zokuBamba

Imicimbi yokubeka indawo kakhulu ngokubhekisele kwixesha eliqhelekileyo. Ukwamkela ukupheliswa komjikelo wamaza iqhosha apha.

Indawo ethe tyaba Emva kokudibanisa ucingo kwi-oscilloscope, iya kunika ukufundwa kwe-sine wave. Le wave ayihlali isembindini okanye ithatha isikrini esigcweleyo. Jika i-knob yendawo ethe tye ngokwewotshi ukuba ayithathi isikrini esigcweleyo. Yiguqule ngokuchaseneyo newashi ukuba uziva ngathi ithatha indawo eninzi kakhulu kwiscreen. Indawo emi nkqo Ngoku ukuba i-sine wave yakho igubungela isikrini sonke, kuya kufuneka uyenze ibe sendaweni egxile kuyo. Ukuba umtshangatshangiso ukwicala elingaphezulu lesikrini jika i-knob ngokwewotshi ukuyihlisa. Ukuba ingezantsi kwescreen sakho kwaye uyijikeleze ngokungqinelana newotshi.

Sebenzisa iTrigger

Ukucofa iswitshi kunokuba liqhina okanye iswitshi. Uza kubona unxantathu omncinci omthubi kwicala lasekunene lesikrini sakho. Leyo yinqanaba lokuqalisa. Lungisa eli nqanaba lokuqala ukuba umboniso wakho ubonakalisile okanye awucaci.

Sebenzisa iVoltage / div kunye nexesha / div

Ukujikeleza ezi ziqhina kuya kubangela utshintsho kubalo lwakho. Nokuba zithini na ezi zixhobo zimbini, isiphumo siya kufana. Lubalo kuphela oluza kwahluka. Ukujikeleza kweVoltage / div knobs kuyakwenza ukuba igrafu yakho ime ngokuthe nkqo okanye mfutshane kwaye ujikeleze ixesha / i-div knob iya kwenza igrafu yakho ngokuthe tye ide okanye mfutshane. Ukulungiselela ukusebenzisa i-volt / i-div kunye ne-1 yexesha / i-div ixesha elide njengoko ubona umjikelo ojikelezayo. Ukuba awukwazi ukubona umjikelo ogcweleyo wokujikeleza kulungiso unokuluguqula ngokweemfuno zakho kwaye usebenzise olo seto kubalo lwakho.

Ixesha lokulinganisa kunye nokuBala amaRhoqo

Masithi ndisebenzise i-0.5 volts kwi-volt / div oko kuthetha ukuba icandelo ngalinye limele .5 voltages. Kwakhona ii-2ms ngexesha / div oko kuthetha ukuba isikwere ngasinye zii-millisecond ezi-2. Ngoku ukuba ndifuna ukubala ixesha emva koko kuya kufuneka ndijonge ukuba mangaphi amacandelo okanye izikwere ezithatha ngokuthe tye kumjikelo ojikelezayo wamaza.

Ukulinganisa-ixesha-kunye nokuBala-ukuRhoqo

Ixesha lokubala

Yithi ndifumene ukuba kuthatha izahlulo ezili-9 ukwenza umjikelo opheleleyo. Emva koko ixesha liphindaphindwe kuseto lwexesha / i-div kunye nenani lamacandelo. Ke kule meko 2ms * 9 = 0.0018 imizuzwana.

Ukubala rhoqo

Ngoku, ngokomgaqo, F = 1 / T. Nanku uF ubude kunye noT ixesha. Ke ubude, kule meko, iya kuba ngu-F = 1 / .0018 = 555 Hz.

Unokubala ezinye izinto ngokusebenzisa ifomula F = C / λ, apho i-λ ubude bobude kunye no-C sisantya sombane esisisantya sokukhanya.

isiphelo

I-oscilloscope sisixhobo esibaluleke kakhulu kwindawo yombane. I-oscilloscope isetyenziselwa ukujonga utshintsho olukhawuleza kakhulu kumbane ekuhambeni kwexesha. Yinto Imultimeter andinakwenza. Apho i-multimeter ikubonisa kuphela amandla ombane, i-oscilloscope inokusetyenziselwa yenze igrafu. Ukusuka kwigrafu, unokulinganisa ngaphezulu kwamandla ombane, anje ngexesha, ubude, kunye nobude bebude. Ke kubalulekile ukuba ufunde malunga nemisebenzi ye-oscilloscope.

NdinguJoost Nusselder, umseki weZixhobo zeGqirha, umthengisi womxholo, kunye notata. Ndiyathanda ukuzama izixhobo ezitsha, kwaye kunye neqela lam ndiye ndenza amanqaku ebhlog anzulu ukusukela ngo-2016 ukunceda abafundi abathembekileyo ngezixhobo kunye neengcebiso zokwenza.
