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
I-oscilloscope ilinganisa unikezelo lwamandla ombane kuwo nawuphi na umthombo kwaye ibonisa i-voltage yevoltage ngokuchasene negrafu yexesha kwiscreen sedijithali esincanyathiselwe kuyo. Le grafu isetyenziswa kwiinkalo ezahlukeneyo zobunjineli bombane kunye neyeza. Ngenxa yokuchaneka kunye nokubonakaliswa okubonakalayo kwedatha, ii-oscilloscopes sisixhobo esisetyenziswa ngokubanzi. Ekuboneni kokuqala, kunokubonakala kungekho nto ikhethekileyo kodwa kunokuba luncedo kakhulu ekuqondeni indlela umqondiso oziphatha ngayo. Ukubeka iliso kwinguqu eqhubekayo kunokukunceda ukuba ufumane iinkcukacha ezibukhali obungenakukwazi ukuzifumana ngaphandle kwegrafu ephilayo. Siza kukufundisa ukufunda isikrini se-oscilloscope ngeenjongo zonyango kunye nezobunjineli eziqhelekileyo.
Kule posi siza kugubungela:
Ukusetyenziswa kwe-Oscilloscope
Ukusetyenziswa kwe-oscilloscope ibonakala kakhulu kwiinjongo zophando. Kwinjineli yombane, inika imbonakalo ethe tye kwaye ichanekile yokubonwa kwemisebenzi ye-wave entsonkothileyo. Ngaphandle kwezona ziseko, ukuphindaphinda, kunye nokuphakama, zinokusetyenziselwa ukufundela nayiphi na ingxolo kwiisekethe. Imilo yamaza inokujongwa nayo. Kwinkalo yesayensi yezonyango, ii-oscilloscopes zisetyenziselwa ukwenza iimvavanyo ezahlukeneyo entliziyweni. Utshintsho oluqhubekayo lwevolthi ngexesha liguqulelwa ekubetheni kwentliziyo. Ukujonga igrafu kwii-oscilloscopes, oogqirha banokuqonda ulwazi olubalulekileyo malunga nentliziyo.
Ukufunda isikrini se-Oscilloscope
Emva kokuba uqhagamshele iinkqubo kumthombo ombane kwaye wakwazi ukufumana imveliso kwiscreen, kuya kufuneka ukwazi ukufunda nokuqonda ukuba kuthetha ntoni na ukuphuma. Iigrafu zithetha izinto ezahlukeneyo kubunjineli nakumayeza. Siza kukunceda uqonde zombini ngokuphendula eminye yemibuzo eqhelekileyo.
Ungawulinganisa njani umbane we-AC kunye ne-Oscilloscope?
Ukutshintsha komthombo wangoku okanye ombane we-AC utshintsha indlela yokuhamba malunga nexesha. Ke, igrafu efunyenwe kumbane we-AC yintsimbi ye-sine. Singa Bala ubungakanani, Amplitude, ixesha, iingxolo, njl njl kwigrafu.
Inyathelo 1: Ukuqonda iNqanaba
Kukho iibhokisi ezincinci zesikwere kwiscreen se-oscilloscope yakho. Isikwere ngasinye kuthiwa lisahlulo. Isikali, nangona kunjalo, lixabiso olinike isikwere ngasinye, okt ulwahlulo. Kuxhomekeka kwinqanaba oseta kuzo zombini izembe ufundo lwakho luya kwahluka, kodwa baya kuguqulela kwinto enye ekugqibeleni.
Inyathelo 2: Yazi nkqo kunye namaCandelo athe tyaba
Kuyo yonke i-oxis ethe tyaba okanye i-X-axis, amaxabiso oza kuwafumana abonisa ixesha. Kwaye sinamaxabiso ombane kwi-Y-axis. Kukho iqhina kwicandelo elithe nkqo lokuseta iivolthi ngecandelo ngalinye (volts / div) ixabiso. Kukho iqhina kwicandelo elithe tyaba nalo elimisela ixesha ngokwecandelo (ixesha / div) ngexabiso. Ngokwesiqhelo, amaxabiso exesha alisetwanga ngemizuzwana. I-Milliseconds (ms) okanye ii-microseconds zixhaphake kakhulu kuba umlinganiso wevolthi yokulinganisa ubukhulu becala ubekwa kwi-kilohertz (kHz). Amaxabiso ombane afumaneka kwii-volts (v) okanye kwi-millivolts.
Inyathelo 3: Cofa iiNqanawa zokuBeka
Zimbini ezinye izikhonkwane, zombini kwindawo ethe tyaba kunye necandelo le-oscilloscope, ekuvumela ukuba uhambise yonke igrafu / inani lomqondiso kwi-X kunye ne-Y-axis. Oku kunokuba luncedo kakhulu ukufumana idatha echanekileyo kwiscreen. Ukuba ufuna idatha echanekileyo kwigrafu, ungahambisa igrafu kwaye uyihambise kunye nencam yesikwere sokwahlula. Ngale ndlela, unokuqiniseka ngokubalwa kwamacandelo. Nangona kunjalo, ungalibali ukuqaphela indawo esezantsi yegrafu.
Inyathelo 4: Ukuthatha iMilinganiselo
Nje ukuba usete amaqhina kwimeko efanelekileyo, unako qalisa ukuthatha imilinganiselo. Ukuphakama okuphezulu okuphezulu okuya kufikelela kwigrafu kwi-equilibrium kuthiwa kukuphakama. Yitsho, usete isikali kwi-Y-axis njenge-1volts kwicandelo ngalinye. Ukuba igrafu yakho ifikelela kwizikwere ezi-3 ezincinci ukusuka kwi-equilibrium, ke ukuphakama kwayo zii-3volts.
Kutheni amaza amakhulu abonwa kwi-Oscilloscope
Amanye amaqhina akwindawo ethe nkqo kunye ethe tyaba angacofa ukutshintsha isikali segrafu. Ngokutshintsha isikali, uza kungena uphume. Ngenxa yesikali esikhulu, yithi, iiyunithi ezi-5 kwisahlulo ngasinye, amaza amakhulu aya kubonakala kwi-oscilloscope.Yintoni i-DC Offset kwi-Oscilloscope
Ukuba intsingiselo ye-wave amplitude, ingu-zero, iliza lenziwa ngendlela yokuba i-X-axis inexabiso le-zero kulungelelwaniso (amaxabiso e-Y-axis). Nangona kunjalo, ezinye zeefomathi zenziwe ngaphezulu kwe-X-axis okanye zibethe i-X-axis. Kungenxa yokuba ukuphakama kwabo kuthetha ukuba ayisiyi-zero, kodwa ngaphezulu okanye ngaphantsi kwe-zero. Le meko ibizwa ngokuba yiDC offset.
Kutheni le nto amaza amakhulu ebonwa kwi-Oscilloscope emele iVentricular Contraction
Xa amaza amakhulu ebonwa kwi-oscilloscope, imele ukusikwa kwe-ventricular. Amagagasi makhulu kuba isenzo sokumpompa kwee-ventricle zentliziyo somelele kakhulu kune-atria. Kungenxa yokuba i-ventricle impompoza igazi liphuma entliziyweni, liye kuwo wonke umzimba. Ke, ifuna isixa esikhulu samandla. Oogqirha bajonga amaza kwaye bafunda amaza akhiwe kwi-oscilloscope ukuqonda imeko ye-ventricles kunye ne-atria kwaye ekugqibeleni, nentliziyo. Nawuphi na ummo ongaqhelekanga okanye inqanaba lokwakheka kwamaza libonisa iingxaki zentliziyo abanokuthi bathambekele kuzo oogqirha.
Jonga ulwazi olongezelelweyo kwiScreen
I-oscilloscopes yanamhlanje ayibonisi kuphela igrafu kodwa iseti yolunye idatha nayo. Eyona nto ixhaphakileyo kwezi datha kukuhamba rhoqo. Kuba i-oscilloscope inika idatha ehambelana nexesha elithile, ixabiso lamaxesha anokuqhubeka ngokutshintsha malunga nexesha. Ixabiso lotshintsho luxhomekeke kwisifundo sovavanyo. Iinkampani ezenza umgangatho oscilloscopes ophezulu bahlala bezama ukuphucula amava omsebenzisi ngezixhobo zabo kwaye batyhale umda. Ngale njongo engqondweni, babeka inani elikhulu kuseto olongezelelweyo lwesixhobo. Izinketho zokugcina igrafu, ukuqhuba into ngokuphindaphindiweyo, ukukhenkceza igrafu, njl. Njengabaqalayo, ukukwazi ukufunda nokuqokelela idatha kwigrafu kuko konke okudingayo. Awudingi ukuziqonda zonke ekuqaleni. Nje ukuba ukhululeke ngayo, qala ukhangele amaqhosha kwaye ubone ukuba loluphi utshintsho oluzayo kwiscreen.isiphelo
I-oscilloscope sisixhobo esibalulekileyo kwicandelo lezesayensi yezonyango kunye nobunjineli bombane. Ukuba unayo nayiphi na imizekelo emidala yee-oscilloscopes, sicebisa ukuba uqale ngayo. Kuya kuba lula kwaye kungadideki kuwe ukuba uqala ngento esisiseko.
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.
