Ungahle ubone izangoma eziningi noma abenzi bemilingo ngama-wands abo kuma-movie, akunjalo? Lezi zingubo zabenza baba namandla amakhulu futhi cishe babekwazi ukwenza konke. Huh, uma lokhu bekuyiqiniso. Kepha uyazi, cishe wonke umcwaningi nelebhu uza ne-wand magic futhi. Yebo, lokhu kuyi- i-oscilloscope lokho kwavula indlela yokwakhiwa komlingo. 
Ngo-1893, ososayensi basungula i-gizmo enkulu, i-oscilloscope. Indima enkulu yalo mshini ukuthi kungathatha ukufundwa kwezimpawu zikagesi. Lo mshini ungakha futhi izakhiwo zesiginali kwigrafu. Lawa makhono akhukhule kakhulu ukuthuthukiswa kwemikhakha kagesi nezokuxhumana.
Kule nkathi, ama-oscilloscopes anezibonisi futhi akhombisa ukushaya kwenhliziyo noma isignali kakhulu. Kepha ngenxa yobuchwepheshe ama-oscilloscopes ahlukaniswa abe izinhlobo ezimbili. I-oscilloscope yedijithali ne-oscilloscope ye-analog. Incazelo yethu izokunikeza umbono ocacile wokuthi iyiphi oyidingayo.
Kulokhu okuthunyelwe sizomboza:
Yini i-Analog oscilloscope?
Ama-oscilloscopes we-analog kumane kunguhlobo oludala lwama-oscilloscopes edijithali. Lawa magajethi eza nezici ezingatheni nokuhamba. Isibonelo, lawa ma-oscilloscopes eza nesibonisi esidala se-cathode ray tube, umkhawulokudonsa we-frequency limited.

Lapho isazi sefilosofi saseFrance u-André Blondel eqala ukusungula i-oscilloscope, yayivame ukuhlela amasiginali kagesi ngemishini kwigrafu. Njengoba yayinemikhawulo eminingi, ngo-1897 uKarl Ferdinand Braun wengeza ithubhu le-cathode ray ukuze abone isignali ekhonjisiwe. Ngemuva kokuthuthuka okuncane, sathola i-oscilloscope yethu yokuqala ye-analog ngo-1940.
Izici nobuchwepheshe
Ama-oscilloscopes we-analogi alula kakhulu phakathi kwalabo abakhona manje emakethe. Phambilini, lawa ma-oscilloscopes enzeka ngokunikela nge-CRT noma i-cathode ray tube ukukhombisa isignali kepha okwamanje, ungathola i-LCD ekhonjiswe kalula. Ngokuvamile, lezi zinamashaneli ambalwa kanye ne-bandwidth, kepha lokhu kwanele kumasifundisane alula.
Ukusebenziseka Ezikhathini Zanamuhla
Yize i-oscilloscope ye-analog ingazwakala njengeyesidala, lokhu kwanele kuwe uma imisebenzi yakho ingaphakathi kwekhono le-oscilloscope. Lawa ma-oscilloscopes kungenzeka angabi nezinketho eziningi zesiteshi njengeyedijithali kepha kwabaqalayo, lokhu kungaphezu kokwanele. Ngakho-ke, udinga ukwazi izidingo zakho kuqala ngaphandle kohlobo.
Yini i-Digital Oscilloscope?
Ngemuva kwenani elikhulu lomzamo nentuthuko, i-oscilloscope yedijithali yeza. Yize umthetho oyisisekelo womsebenzi womabili ofanayo uyefana, idijithali iza namandla angeziwe okuphatha. Ingagcina igagasi ngezinombolo ezithile zedijithali futhi ilikhombise kusibonisi liyisusa ikhodi.
Umlando
Ukuqala nge-oscilloscope yokuqala, ososayensi baqhubeka nokucwaninga ukuyithuthukisa ngokwengeziwe. Ngemuva kokuthuthuka okumbalwa, i-oscilloscope yokuqala yedijithali yafika emakethe ngonyaka we-1985. Lawa ma-oscilloscopes ayenomkhawulokudonsa obanzi ngokumangazayo, ukusetshenziswa kwamandla okuphansi, nokunye okunye okuhle kakhulu.
Izici nobuchwepheshe
Yize le kuyimikhiqizo ephezulu kakhulu emakethe, kukhona nokuhlukahluka okuthile phakathi kwama-oscilloscopes edijithali ngokobuchwepheshe bawo. Lezi izi:
- Isitoreji Sedijithali Ama-Oscilloscopes (i-DSO)
- I-Digital Stroboscopic Oscilloscopes (DSaO)
- I-Digital Phosphor Oscilloscopes (DPO)
DSO
Ama-Oscilloscopes Wokugcina Kwedijithali aklanyelwe nje futhi asetshenziswa kabanzi ngama-oscilloscopes edijithali. Ngokuyinhloko, izibonisi zohlobo lwe-raster zisetshenziswa kulawa ma-oscilloscopes. Okuwukuphela kwempendulo yalokhu uhlobo lwama-oscilloscopes ukuthi lawa ma-oscilloscopes awakwazi ukuthola ukuqina kwesikhathi sangempela.
I-DSaO
Ukufakwa kwebhuloho lesampula ngaphambi kwesekethe lokunamathisela noma le-amplifier kwenza kucace bha. Ibhuloho lesampula lisampula isignali ngaphambi kwenqubo yokukhulisa. Njengoba isignali eyisampuli ingeyemvamisa ephansi, kusetshenziswa i-bandwidth amplifier ephansi eyenza igagasi lokukhiphayo libe bushelelezi futhi linembe.
I-DPO
I-Digital Phosphor Oscilloscope uhlobo oludala kakhulu lwe-oscilloscope yedijithali. Lawa ma-oscilloscopes awasetshenziswa kabanzi kulezi zinsuku kepha lawa ma-oscilloscopes akhiwe ngendlela ehluke ngokuphelele. Ngakho-ke, lawa ma-oscilloscopes anganikela ngamakhono ahlukile ngenkathi kuvuselelwa kabusha isignali ekubonisweni.
Ukusebenziseka Ezikhathini Zanamuhla
Ama-oscilloscopes edijithali yi-oscilloscope ephezulu kakhulu manje etholakala emakethe. Ngakho-ke, akukho kungabaza ngokusetshenziswa kwazo ezikhathini zanamuhla. Kepha kunento eyodwa okufanele uyikhumbule ukuthi, kuzofanele ukhethe okufaneleka kahle kakhulu. Ngoba ubuchwepheshe bama-oscilloscopes buyahluka ngokuya ngezinhloso zabo.
I-Analog Oscilloscope Vs Digital Oscilloscope
Ngokungangabazeki, i-digital oscilloscope uthola isandla esiphezulu phezu kwe-analog, eqhathanisa umehluko othile. Kodwa lo mehluko ungase ume ungasizi ngenxa yesidingo sakho somsebenzi. Ukuze uxazulule le nkinga, sinikeza ukuqhathanisa okufushane ukukuvumela ukuthi uvume umehluko oyinhloko.
Iningi lama-oscilloscopes edijithali afaka isibonisi esibukhali futhi esinamandla sokubonisa i-LCD noma i-LED. Ngenkathi, ama-oscilloscopes amaningi we-analog eza nezibonisi zeCRT. Ama-oscilloscopes edijithali eza nenkumbulo egcina inani ledijithali ledijithali futhi futhi angalicubungula.
Ukuqaliswa kwe-ADC noma i-analog kumjikelezo wedijithali wokuguqula kwenza igebe elikhulu phakathi kwe-analog ne-oscilloscope yedijithali. Ngaphandle kwalezi zinsiza, ungaba neziteshi eziningi zamasiginali ahlukile neminye imisebenzi eyengeziwe engatholakali kwi-oscilloscope ejwayelekile ye-analog.
Isincomo Sokugcina
Ngokuyinhloko, isimiso esisebenzayo sama-oscilloscopes we-analog nedijithali ayafana. I-oscilloscope yedijithali ifaka obunye ubuchwepheshe obengeziwe obengeziwe bokucubungula okungcono kwamasignali nokukhohlisa ngeziteshi eziningi. Ngokuphambene nalokho, i-oscilloscope ye-analog ingafaka okuncane kokubonisa okudala nezici. Ungacabanga ukuthi zifana ne-multimeter negrafu, kepha kukhona okuyisisekelo umehluko phakathi kwe-oscilloscope ne-graphing multimeter.
Uma unamathele umehluko phakathi kwe-analog ne-oscilloscope yedijithali, khona-ke kufanele nakanjani uye nge-oscilloscope yedijithali. Ngoba i-oscilloscope yedijithali ibangela imali eningi impela kune-analog eyodwa. Emisebenzini elula yasendlini noma elebhu, ama-analog noma ama-oscilloscopes edijithali awenzi mehluko.
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.
