Usenokuba ubonile abaninzi abathakathi okanye oosiyazi ngeentonga zabo kwiimuvi, akunjalo? Ezi ntambo zazibenza babe namandla kakhulu kwaye phantse babenokwenza yonke into. Hee, ukuba ezi beziyinyani. Kodwa uyazi, phantse wonke umphandi kunye nelebhu uza nentonga yomlingo nayo. Ewe, oku ku i-oscilloscope eyavula indlela yokuveliswa komlingo. 
Ngomnyaka we-1893, izazinzulu zenza i-gizmo enkulu, i-oscilloscope. Indima ephambili yomatshini yayikukuba inokuthatha ukufundwa kwemiqondiso yombane. Lo matshini unokucwangcisa iimpawu zomqondiso kwigrafu. Ezi zakhono ziphazamise uphuhliso lwecandelo lombane kunye nonxibelelwano kakhulu.
Ngeli xesha, ii-oscilloscopes zinemiboniso kwaye zibonisa i-pulse okanye isignali ebukhali kakhulu. Kodwa ngenxa yetekhnoloji i-oscilloscopes yahlulwa yaba ziindidi ezimbini. I-oscilloscope yedijithali kunye ne-analog oscilloscope. Inkcazo yethu iya kukunika umbono ocacileyo wokuba yeyiphi oyifunayo.
Kule posi siza kugubungela:
Yintoni iAnalog oscilloscope?
Ii-oscilloscopes ze-Analog ziinguqulelo ezindala zee-oscilloscopes zedijithali. Ezi gajethi ziza kunye neempawu ezingaphantsi kancinci kunye nokusebenziseka. Ngokomzekelo, ezi oscilloscopes ziza kunye nomboniso omdala we-cathode ray, i-bandwidth elinganiselweyo, njl.
imbali
Xa isazi sefilosofi saseFransi u-André Blondel waqala ukwenza i-oscilloscope, yayisetyenziselwa ukucwangcisa iimpawu zombane ngomatshini kwigrafu. Njengoko yayinezithintelo ezininzi, ngo-1897 uKarl Ferdinand Braun wongeza ityhubhu ye-cathode ray ukuze abone umqondiso ekuboniseni. Emva kophuhliso olumbalwa, safumana i-analog oscilloscope yethu yokuqala ngo-1940.
Iimpawu kunye neTekhnoloji
I-Analog oscilloscopes zezona zilula phakathi kwezo zikhoyo ngoku kwimarike. Ngaphambili, ezi oscilloscopes zenzeke ukuba zinikeze iCRT okanye i-cathode ray ityhubhu ukubonisa isignali kodwa okwangoku, unokufumana i-LCD eboniswe ngokulula. Ngokubanzi, ezi zinetshaneli ezimbalwa kunye ne-bandwidth, kodwa ezi zanele kwiiworkshops ezilula.
Ukusebenziseka kwixesha langoku
Nangona i-analog oscilloscope inokuvakala ngathi isemva, oku kwanele kuwe ukuba imisebenzi yakho ingaphakathi kwisakhono se-oscilloscope. Ezi oscilloscopes zisenokungabi nokhetho oluninzi lwetshaneli njengedijithali kodwa kumntu oqalayo, oku kungaphezulu kokwaneleyo. Ke, kuya kufuneka wazi iimfuno zakho kuqala nokuba loluphi na uhlobo.
Yintoni iDigital Oscilloscope?
Emva komzamo omkhulu kunye nenkqubo yophuhliso, i-oscilloscope yedijithali yeza. Nangona umgaqo osisiseko wokusebenza kuzo zombini ezi zinto ufana, idijithali iza nesakhono esongezelelweyo sokulawula. Inokugcina amaza ngamanani athile edijithali kwaye iyibonise kumboniso oyicacisayo.
imbali
Ukuqala kwi-oscilloscope yokuqala, izazinzulu ziye zaqhubeka nophando ukuze ziphuhlise ngakumbi nangakumbi. Emva kophuhliso oluthile, i-oscilloscope yokuqala yedijithali yeza kwimarike ngonyaka ka-1985. Ezi oscilloscopes zine-bandwidth ebanzi ngokumangalisayo, ukusetyenziswa kwamandla aphantsi, kunye nezinye izinto ezinkulu ezongezelelweyo nazo.
Iimpawu kunye neTekhnoloji
Nangona ezi izezona mveliso ziphezulu zentengiso, kukwakho umahluko phakathi kwee-oscilloscopes zedijithali ngokwetekhnoloji yazo. Zezi:
- I-Digital Storage Oscilloscopes (DSO)
- I-Digital Stroboscopic Oscilloscopes (DSaO)
- I-Digital Phosphor Oscilloscopes (DPO)
I-DSO
I-Digital Storage Oscilloscopes ziyilwe ngokulula kwaye zisetyenziswa ngokubanzi ii-oscilloscopes zedijithali. Ikakhulu, iziboniso zohlobo lwe-raster zisetyenziswa kwezi oscilloscopes. I-drawback kuphela yale nto uhlobo lwe oscilloscopes kukuba ezi oscilloscopes azikwazi ukufumana ubunzulu bexesha lokwenyani.
DSaO
Ukubandakanywa kwebhulorho yeesampuli phambi kwe-attenuator okanye i-amplifier circuit yenza ukuba ihluke kakhulu. Isampulu ibhulorho iisampulu umqondiso phambi kwenkqubo yokukhulisa. Njengoko umqondiso wesampulu uphantsi rhoqo, i-amplifier ye-bandwidth ephantsi iyasetyenziswa eyenza i-wave wave igudile kwaye ichanekile.
Dpo
I-Digital Phosphor Oscilloscope lolona hlobo ludala lwe-digital oscilloscope. Ezi oscilloscopes azisetyenziswa kakhulu kule mihla kodwa ezi oscilloscopes zolwakhiwo olwahluke ngokupheleleyo. Ke, ezi oscilloscopes zinokubonelela ngezakhono ezahlukeneyo ngelixa kusakhiwa kwakhona umqondiso kumboniso.
Ukusebenziseka kwixesha langoku
Ii-oscilloscopes zedijithali zezona ziphezulu-notshi ze-oscilloscope ezikhoyo ngoku kwimarike. Ke, akukho mathandabuzo malunga nokusetyenziswa kwazo kumaxesha anamhlanje. Kodwa inye into ekufuneka uyikhumbule ukuba, kuya kufuneka ukhethe eyona ifanelekileyo. Ngenxa yokuba iteknoloji yeeoscilloscopes iyahluka ngokweenjongo zazo.
I-Analog Oscilloscope Vs Digital Oscilloscope
Ngokuqinisekileyo, i-oscilloscope yedijithali ifumana isandla esiphezulu kwi-analog, ithelekisa ezinye iiyantlukwano. Kodwa le yantlukwano inokuma ingasebenzi kuwe ngenxa yemfuno yakho yomsebenzi. Ukusombulula le ngxaki, sinika uthelekiso olufutshane ukukuvumela ukuba uvume iiyantlukwano eziphambili.
Uninzi lwe oscilloscopes digital ziquka ezibukhali kwaye enamandla ukubonisa LCD okanye iziboniso LED. Ngelixa, uninzi lweeoscilloscopes ze-analog ziza neziboniso zeCRT. Ii-oscilloscopes zeDijithali ziza nenkumbulo egcina ixabiso lamanani edijithali lophawu kwaye iyakwazi ukuyiqhuba.
Ukuphunyezwa kwe-ADC okanye i-analog to digital converter circuit yenza umsantsa omkhulu phakathi kwe-analog kunye ne-digital oscilloscope. Ngaphandle kwezi zibonelelo, unokuba namajelo amaninzi emiqondiso eyahlukeneyo kunye neminye imisebenzi eyongezelelweyo engafumanekiyo kwi-analog oscilloscope ngokubanzi.
Ingcebiso yokugqibela
Ngokusisiseko, umgaqo wokusebenza we-analog kunye ne-digital oscilloscopes ziyafana. I-oscilloscope yedijithali ibandakanya iitekhnoloji ezongezelelweyo ezimbalwa zokusetyenzwa ngcono kophawu kunye nokuqhathwa ngamatshaneli amaninzi. Ngokuchasene noko, i-analog oscilloscope inokubandakanya umboniso omncinci omdala kunye neempawu. Unokucinga ukuba zifana ne-multimeter enegrafu, kodwa kukho ezinye ezisisiseko Umahluko phakathi kwe-oscilloscope kunye ne-multimeter ye-graphing.
Ukuba ubambekile kumahluko phakathi kwe-analog kunye ne-oscilloscope yedijithali, ngokuqinisekileyo kuya kufuneka uye kwi-oscilloscope yedijithali. Kuba i-oscilloscope yedijithali ibangela iirandi ezimbalwa ngakumbi kune-analog. Kwimisebenzi elula yasekhaya okanye yaselabhoratri, i-analog okanye i-oscilloscopes yedijithali azenzi mahluko.
