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 zibambela ngokuthe ngqo ii-multimeters. Yintoni enokuyenza i-multimeter, i-oscilloscopes ingayenza ngcono. Kwaye ngokunyuka kokusebenza, ukusetyenziswa kwe-oscilloscope yindlela enzima kakhulu kune-multimeters, okanye naziphi na ezinye izixhobo zokulinganisa i-elektroniki. Kodwa, ayisiyiyo isayensi ye-rocket ngokuqinisekileyo. Apha siza kuxoxa ngeziseko ekufuneka uzazi ngelixa usebenza i-oscilloscope. Siza kugubungela ubuncinci kwizinto ekufuneka uzazi ukuze wenze umsebenzi wakho wenziwe ngeeoscilloscopes.
Kule posi siza kugubungela:
Amacandelo abalulekileyo e-Oscilloscope
Ngaphambi kokuba singene kwisifundo, kukho izinto ezimbalwa ekufuneka uzenzile Yazi malunga ne-oscilloscope. Njengomatshini ontsonkothileyo, unamaqhina amaninzi, amaqhosha ekusebenzeni kwawo ngokupheleleyo. Kodwa ke, awunyanzelekanga ukuba wazi ngayo yonke enye yazo. Siza kuthetha ngezona ndawo zibalulekileyo zomgangatho ekufuneka uyazi ngaphambi kokuba uhambe.Iindlela
I-oscilloscope ilungile kuphela ukuba ungayiqhagamshela kwisiginali, kwaye ngenxa yoko ufuna iprobes. Inkqubo zinegalelo elinye lokuhambisa umqondiso ukusuka kwisekethe yakho ukuya kwinqanaba. Iiprobes eziqhelekileyo zineengcebiso ezibukhali kunye nocingo lomhlaba ngayo. Uninzi lweeproses zinokuthothisa umqondiso ukuya kumaxesha alishumi umqondiso wokuqala ukunika ukubonakala okungcono.Ukhetho lwesitishi
Eyona oscilloscopes ineendlela ezimbini okanye ezingaphezulu. Kukho iqhosha elizinikeleyo ecaleni kwazo zonke izibuko lejelo ukukhetha elo jelo. Nje ukuba ukhethe, unokujonga iziphumo kweso sitishi. Uyakwazi ukujonga iziphumo ezimbini nangaphezulu ngaxeshanye ukuba ukhetha ngaphezulu kwesinye isiteshi ngexesha. Ewe kunjalo, kufuneka kubekho ukufakwa kwesiginali kwizibuko lesitishi.Ukuqalisa
Ulawulo lwenkungu kwi-oscilloscope lubeka indawo apho i-scan kwifom ye-wave iqala khona. Ngamazwi alula, ngokubangela i-oscilloscope uzinzisa imveliso esiyibonayo kumboniso. Kwii-oscilloscopes ze-analogu, kuphela xa inqanaba elithile levolthi ifikelelwe kwifom ye-wave iya kuqala ukuskena. Oku kuyakwenza ukuba ukuskena kwifom yokuqalisa ukuba kuqalise ngaxeshanye kumjikelo ngamnye, okwenza ukuba ifom ye-wave ezinzileyo iboniswe.Ukuma ngokuthe nkqo
Olu lawulo kwi-oscilloscope lutshintsha inzuzo yesikhulisi esilawula ubungakanani besiginali kwi-axis ethe nkqo. Ilawulwa liqhina elijikelezileyo elinamanqanaba ahlukeneyo aphawulwe kuwo. Xa ukhetha umda ongezantsi, iziphumo ziya kuba zincinci kwi-axis ethe nkqo. Xa uya kunyusa inqanaba, iziphumo ziya kusondezwa kwaye kube lula ukuzijonga.Umgca osezantsi
Oku kugqiba indawo ye-axis ethe tyaba. Unokukhetha indawo yokujonga umqondiso nakwesiphi na isikhundla somboniso. Oku kubalulekile ukulinganisa inqanaba lokuphakama komqondiso wakho.Ixesha lexesha
Ilawula isantya esikrinini esikrinini. Ukusuka koku, ixesha lefomathi elinokubalwa linokubalwa. Ukuba umjikelo opheleleyo wefom ye-wave ukuya kwi-10 microseconds ukugqiba, oku kuthetha ukuba ixesha lazo zii-microsecond ezili-10, kwaye ukuphindaphinda kukuphindaphinda kwexesha, okt 1/10 microseconds = 100 kHz.Bamba
Oku kusetyenziselwa ukubamba umqondiso ukusuka kwahluka ngokuhamba kwexesha. Oku kunceda ukugcina umqondiso wokuhamba ngokukhawuleza ngokulula ngakumbi.Ukuqaqamba noLawulo lokuqina
Benza oko bakuthethayo. Zimbini iincakuba zokudibanisa kuzo zonke iindawo ezikuvumela ukuba ulawule ukukhanya kwescreen kwaye uhlengahlengise amandla esignali oyibonayo kumboniso.Ukusebenza ne-Oscilloscope
Ngoku, emva kwazo zonke iintetho zokuqala, masivule indawo kwaye siqale amanyathelo. Akukho kungxama, siya kuhamba inyathelo ngenyathelo:- Xhuma kwi-chord kwaye uvule ubungakanani ngokucinezela iqhosha lokucima / lokucima. Uninzi lwe-oscilloscope yanamhlanje inayo. Eziphelelwe lixesha ziya kuvulwa kuphela ngokuzifaka ngaphakathi.
- Khetha ijelo oza kusebenza nalo kwaye ucime ezinye. Ukuba ufuna ijelo elingaphezulu kwesinye, khetha ezimbini kwaye ucime ezinye njengangaphambili. Guqula inqanaba lomhlaba naphina apho ufuna khona kwaye ukhumbule inqanaba.
- Qhagamshela uphando kwaye usete inqanaba lokuncitshiswa. Olona hlobo lululo yi-10X. Kodwa ungasoloko ukhetha ngokweminqweno yakho kunye nohlobo lomqondiso.
- Ngoku kufuneka ulinganise iphenyo. Ngokwesiqhelo unokufaka iplagi ye-oscilloscope kwaye uqalise ukwenza imilinganiselo. Kodwa i-oscilloscope probes kufuneka ilungiswe ngaphambi kokuba ihlawulwe ukuze iqinisekise ukuba impendulo yabo ithe tyaba.
- Emva kokuba ulungiso lwenziwe, chukumisa incam yesiphelo seprosesa kwisiphelo esifanelekileyo sesekethe yakho kunye nomhlaba kwisiphelo somhlaba. Ukuba yonke into ihamba kakuhle kwaye isekethe iyasebenza, uya kubona umqondiso kwiscreen.
- Ngoku, ngamanye amaxesha awuyi kubona isiginali egqibeleleyo kwangoko. Emva koko kuya kufuneka ukhuphe imveliso ngeqhina lokubangela.
- Ungayibona imveliso ngendlela oyifunayo ngokuhlengahlengisa ivolthi ngecandelo ngalinye kunye nokutshintsha kwamaqhina. Balawula inzuzo ethe nkqo kunye nexesha lesiseko.
- Ukujonga ngaphezulu kwesiginali esinye kunye, qhagamshela enye iprojekhthi yokugcina eyokuqala isadibene. Ngoku khetha la majelo mabini ngaxeshanye. Nako usiya.
isiphelo
Nje ukuba kwenziwe imilinganiselo embalwa, kuya kuba lula ngakumbi ukusebenzisa i-oscilloscope. Njengoko ii-oscilloscopes sesinye sezixhobo eziphambili, kubalulekile ukuba nabani na obandakanyekayo kwizixhobo ze-elektroniki azi indlela yokusebenzisa i-oscilloscope kunye nendlela yokusebenzisa kakuhle.
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.
