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. Funda kabanzi
I-oscilloscope ikala ukunikezwa kwamandla kagesi kwanoma yimuphi umthombo futhi ibonisa igrafu ye-voltage uma iqhathaniswa nesikhathi esikrinini sedijithali esinamathiselwe kuyo. Le grafu isetshenziswa emikhakheni ehlukene yobunjiniyela bakagesi kanye nemithi. Ngenxa yokunemba nokumelwa okubonakalayo kwedatha, ama-oscilloscopes ziyizisetshenziswa ezisetshenziswa kakhulu. Uma uthi nhlá, kungase kubonakale kungelutho olukhethekile kodwa kungaba usizo kakhulu ekuqondeni ukuthi isignali iziphatha kanjani. Ukwengamela ushintsho olungaguquki kungakusiza ukuthi uthole imininingwane ebucayi obungeke ukwazi ukuyithola ngaphandle kwegrafu ebukhoma. Sizokufundisa ukufunda isikrini se-oscilloscope ngezinjongo ezithile ezivamile zezokwelapha nobunjiniyela.
Kulokhu okuthunyelwe sizomboza:
Ukusetshenziswa kwe-Oscilloscope
Ukusetshenziswa kwe-oscilloscope ibonakala kakhulu ngenhloso yocwaningo. Kubunjiniyela kagesi, inikezela ngesibonisi esibucayi nesinembile semisebenzi yamagagasi eyinkimbinkimbi. Ngaphandle kwezisekelo eziyisisekelo, imvamisa, nobubanzi, zingasetshenziselwa ukutadisha noma yimiphi imisindo esekelweni. Ukuma kwamagagasi kungabukwa futhi. Emkhakheni wesayensi yezokwelapha, ama-oscilloscopes asetshenziselwa ukwenza izivivinyo ezahlukahlukene enhliziyweni. Ukushintshwa okuqhubekayo kwamandla ngesikhathi kuhunyushwa ekushayeni kwenhliziyo. Uma bebheka igrafu kuma-oscilloscopes, odokotela bangathola imininingwane ebalulekile mayelana nenhliziyo.
Kufundwa i-Oscilloscope Screen
Ngemuva kokuthi uxhume ama-probes kumthombo we-voltage futhi wakwazi ukuthola okukhiphayo esikrinini, kufanele ukwazi ukufunda futhi uqonde ukuthi kusho ukuthini lokho kukhishwa. Amagrafu asho izinto ezihlukile zobunjiniyela nemithi. Sizokusiza uqonde yomibili ngokuphendula eminye yemibuzo ejwayelekile.
Ungayilinganisa kanjani i-AC Voltage nge-Oscilloscope?
Ukushintshana komthombo wamanje noma amandla we-AC kushintsha umkhombandlela wokugeleza maqondana nesikhathi. Ngakho-ke, igrafu etholwe kumthamo we-AC yigagasi le-sine. Singakwazi abale imvamisa, ubukhulu, isikhathi, imisindo, njll. kusuka kugrafu.
Isinyathelo 1: Ukuqonda iSikali
Kukhona amabhokisi ayisikwele amancane esikrinini se-oscilloscope yakho. Sinye naleto tikwele sibitwa ngekwehlukaniswa. Isikali, nokho, yinani olinikeza isikwele ngasinye, isb ukuhlukaniswa. Ngokuya ngesilinganiso osibeka kuzo zombili izimbazo ukufundwa kwakho kuzohluka, kepha kuzohumushela entweni efanayo ekugcineni.
Isinyathelo 2: Yazi Izigaba Eziqondile Nezivundlile
Ngaphesheya kokuvundlile noma i-X-eksisi, amanani ozowathola akhombisa isikhathi. Futhi sinamanani wevolthi yonkana i-Y-axis. Kukhona isibonisi esigabeni esime mpo sokusetha ama-voltages ngokuhlukaniswa ngakunye (volts / div) inani. Kukhona idolo engxenyeni evundlile nayo esetha isikhathi inani lokuhlukanisa ngakunye (isikhathi / div). Imvamisa amanani esikhathi awasethiwe ngemizuzwana. Ama-milliseconds (ms) noma ama-microseconds ajwayelekile kakhulu ngoba imvamisa yamandla kagesi evame ukulinganiselwa ivame ukufikela kuma-kilohertz (kHz). Amanani we-voltage atholakala kuma-volts (v) noma ama-millivolts.
Isinyathelo 3: Shayela ama-Positioning Knobs
Kunezinye izinkinobho ezimbili, zombili ezingxenyeni enezingqimba nengaphezulu ye-oscilloscope, ekuvumela ukuthi uhambise lonke igrafu / isibalo sesiginali ngaphesheya kwe-X ne-Y-axis. Lokhu kungasiza kakhulu ukuthola idatha enembile kusuka esikrinini. Uma ufuna idatha enembile kusuka kugrafu, ungahambisa igrafu nxazonke bese uyifanisa nethiphu lesikwele sokuhlukanisa. Ngale ndlela, ungaqiniseka ngokubalwa kokuhlukaniswa. Noma kunjalo, ungakhohlwa ukubheka ingxenye engezansi yegrafu.
Isinyathelo 4: Ukuthatha Isilinganiso
Lapho ususethe izinkinobho zaba sesimeni esifanele, unga qala ukuthatha izilinganiso. Ukuphakama okuqondile okuphezulu okuzofinyelelwa igrafu kusuka ku-equilibrium kubizwa ngokuthi yi-amplitude. Ithi, usethe isikali ku-Y-axis njengama-1volts esigabeni ngasinye. Uma igrafu yakho ifinyelela izikwele ezi-3 ezincane kunazo zonke kusukela ku-equilibrium, khona-ke ubukhulu bayo bungamavolts ama-3.
Kungani Amagagasi Amakhulu Ebonakala ku-Oscilloscope
Amanye ama-knob asengxenyeni evundlile nesezingqimba angashayelwa ukushintsha isikali segrafu. Ngokushintsha isikali, usondeza ngaphandle nangaphakathi. Ngenxa yesilinganiso esikhudlwana, yithi, ama-5units ngokuhlukana ngakunye, amagagasi amakhulu azobonakala ku-oscilloscope.Yini i-DC Offset ku-An Oscilloscope
Uma ubukhulu be-wave's wave, bungu-zero, igagasi lakheka ngendlela yokuthi i-X-axis inamanani we-zero wokuhlelwa (amanani we-Y-axis). Kodwa-ke, amanye ama-waveforms enziwa ngaphezulu kwe-X-axis noma agxume i-X-axis. Lokho kungenxa yokuthi i-amplitude yabo ayiyona zero, kepha ingaphezulu noma ingaphansi kuka-zero. Lesi simo sibizwa nge-DC offset.
Kungani Amagagasi Amakhulu Ebonakala ku-Oscilloscope Emele Ukuncipha Kwama-Ventricular
Lapho amagagasi amakhulu ebonakala ku-oscilloscope, imele ukusikwa kwe-ventricular. Amagagasi makhulu ngoba isenzo sokumpompa kwama-ventricles enhliziyo sinamandla kakhulu kune-atria. Lokho kungenxa yokuthi i-ventricle iphampa igazi lisuke enhliziyweni, liye kuwo wonke umzimba. Ngakho-ke, kudinga inani elikhulu lamandla. Odokotela baqapha amagagasi futhi bafunde amagagasi akhiwe kwi-oscilloscope ukuqonda isimo se-ventricles kanye ne-atria futhi ekugcineni, nenhliziyo. Noma yikuphi ukuma okungajwayelekile noma isilinganiso sokwakheka kwegagasi kukhombisa izinkinga zenhliziyo odokotela abangathambekela kuzo.
Bheka eminye imininingwane kusikrini
Ama-oscilloscopes ezinsuku zanamuhla awakhombisi igrafu kuphela kodwa neqoqo lenye idatha futhi. Okuvame kakhulu kuleyo datha imvamisa. Njengoba i-oscilloscope inika idatha ephathelene nesikhathi esithile, inani lemvamisa lingaqhubeka liguquke maqondana nesikhathi. Inani loshintsho lincike esihlokweni sokuhlola. Izinkampani ezenza ama-oscilloscopes ekhwalithi ephezulu bazama njalo ukuthuthukisa ulwazi lomsebenzisi ngamadivayisi wabo futhi bacindezele umngcele. Ngalo mgomo engqondweni, bafaka inani elikhulu lamasethingi angeziwe wedivayisi. Izinketho zokugcina igrafu, sebenzisa okuthile kaninginingi, uqandisa igrafu, njll. Ezinye zezinto ongabona imininingwane kusikrini. Njengokuqala, ukukwazi ukufunda nokuqoqa idatha kusuka kugrafu konke okudingayo. Awudingi ukuziqonda zonke ekuqaleni. Uma usutholile ngayo, qala ukuhlola izinkinobho bese ubona ukuthi iziphi izinguquko eziza esibukweni.Isiphetho
I-oscilloscope iyithuluzi elibalulekile emkhakheni wesayensi yezokwelapha nobunjiniyela kagesi. Uma unamamodeli amadala ama-oscilloscopes, sincoma ukuthi uqale ngawo. Kuzoba lula futhi kungadideki kuwe uma uqala ngento eyisisekelo.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
