Phakathi kwamakhulu ezixhobo ezikhoyo kwimarike yokulinganisa ulwazi kumqondiso othile wombane, oomatshini ababini abaqhelekileyo yimultimeter kunye i-oscilloscope. Kodwa baye bahamba ngotshintsho olukhulu kule minyaka ukuze babe ngcono kwaye basebenze ngokufanelekileyo emsebenzini wabo.
Nangona umsebenzi wezi zixhobo zimbini ufana ngandlela ithile, awufani ngokusebenza kunye nokujonga. Zinezinto ezithile ezenza ukuba zikhetheke kwezinye iindawo. Siza kukuxelela umahluko phakathi kwezi zixhobo zimbini ukuze wazi ukuba yeyiphi eya kuba luncedo kuwe phantsi kweemeko ezahlukeneyo.
Ukwahlulahlula i-Oscilloscope kwiMultimeter yeGrafu
Xa ufuna ukufumana umahluko phakathi kwezinto ezimbini, kufuneka uthelekise amanqaku abo kwaye ufumanise ukuba ngubani owenza umsebenzi ongcono womsebenzi othile. Kwaye yile nto kanye esiyenzileyo apha. Senze uphando olubanzi kwaye saphanda malunga nezinto ezibacwangcisayo aba matshini babini, kwaye sazidwelisela ezantsi apha ngezantsi.
Imbali yeNdalo
Ngelixa isixhobo sokuqala sokuhambisa isalathi yayiyigalvanometer ngo-1820, i-multimeter yokuqala yenziwa kwii-1920s zokuqala. Injineli yaseBritish Post uDonald Macadie wasungula umatshini ekhathazekile yimfuno yokuphatha izixhobo ezininzi ezifunekayo kulondolozo lweesekethe zonxibelelwano.
I-oscilloscope yokuqala yaqanjwa ngo-1897 ngu-Karl Ferdinand Braun, owayesebenzisa i-Cathode Ray Tube (CRT) ukubonisa ukufuduka komnyuli ohamba rhoqo omele uhlobo lomqondiso wombane. Emva kwemfazwe yesibini yehlabathi, iikiti ze-oscilloscope zafunyanwa kwintengiso yeedola ezingama-50.
bandwidth
I-oscilloscopes ezisezantsi ezisezantsi zinomda we-bandwidth oyi-1Mhz (MegaHertz) kwaye ufikelela kwiiMegaHertz ezimbalwa. Kwelinye icala, i-graphing multimeter ine-bandwidth ye-1Khz (KiloHertz) kuphela. I-bandwidth engaphezulu ilingana nokuskena okungaphezulu ngomzuzwana okukhokelela kwiifom zamaza ezichanekileyo nezichanekileyo.
I-Outlook: Ubungakanani kunye neenxalenye ezisisiseko
Ii-Oscilloscopes zizixhobo ezilula kwaye eziphathwayo ezibonakala njengebhokisi encinci. Nangona kukho ezinye iinjongo ezikhethekileyo ezixhonyiweyo. Ukuzoba i-multimeter, kwelinye icala, zincinci ngokwaneleyo ukuba ungaziphatha epokothweni.
Ulawulo kunye nescreen kwicala lasekhohlo nasekunene le-oscilloscope. Kwi-oscilloscope, ubungakanani bescreen bukhulu kakhulu xa kuthelekiswa nescreen esincinci segraphing multimeter. Isikrini sigubungela malunga neepesenti ezingama-50 zomzimba wesixhobo kwi-oscilloscope. Kodwa kwimultimeter yegrafu, imalunga neepesenti ezingama-25. Eminye yeyokulawula kunye negalelo.
Iimpawu zeScreen
Izikrini ze-Oscilloscope zikhulu kakhulu kunendlela ye-graphing multimeter. Kwiskrini se-oscilloscope, kukho igridi enezikwere ezincinci ezaziwa njengamacandelo. Oku kubonelela ngokuguquguquka kunye nokuguquguquka njengephepha lokwenene legrafu. Kodwa akukho gridi okanye ukwahlula kwiscreen semultimeter's screen.
Izibuko lokufaka iiJacks
Ngokubanzi, kukho iindlela ezimbini zokufaka kwi-oscilloscope. Ijelo ngalinye lokufaka lifumana umqondiso ozimeleyo usebenzisa iinkqubo. Kwi-multimeter yegrafu, kukho amazibuko ama-3 okufakelwa okubhalwe i-COM (eqhelekileyo), A (okwangoku), kunye ne-V (yombane). Kukwakho nezibuko lokucuthwa kwangaphandle kwi-oscilloscope engekhoyo kwigrafu yemultimeter.
Ulawulo
Ulawulo kwi-oscilloscope yahlulwe yangamacandelo amabini: ethe nkqo kunye ethe tye. Icandelo elithe tyaba lilawula iimpawu ze-X-axis yegrafu eyenziwe kwiscreen. Icandelo elithe nkqo lilawula i-Y-axis. Nangona kunjalo, akukho zilawuli zokulawula igrafu kwi-graphing multimeter.
Kukho ukucofa okukhulu kwimultimeter yegrafu ekufuneka ujikile kwaye ukhombe kwinto ofuna ukuyilinganisela. Umzekelo, ukuba ufuna ukulinganisa umahluko wevolthi, kuya kufuneka ujike ukucofa ku "V" ophawulwe ngokujikeleza ucofo. Olu lawulo lubekwe kufutshane nescreen se-oscilloscope, kanye phambi kwecandelo elithe nkqo.
Kwimultimeter yegrafu, iziphumo ezingagqibekanga lixabiso. Ukufumana igrafu, kufuneka ucofe kwiqhosha "Auto" ngaphantsi kwesikrini. Ii-Oscilloscopes ziya kukunika igrafu ngokwendalo. Unokufumana ulwazi olongezelelekileyo kwigrafu usebenzisa amaqhina akwicala elime nkqo nakwindawo ethe tye kunye nepaneli ecaleni kwesikrini.
Amaqhosha okubamba ixabiso kunye nokukhupha ixabiso kwiimvavanyo ezintsha abekwe kanye emva kweqhosha "Ngokuzenzekelayo". Amaqhosha okugcina iziphumo kwi-oscilloscope ahlala efumaneka ngaphezulu kwecandelo elithe nkqo.
Iindidi zeSweep
In i-oscilloscope, ungenza ngokwezifiso ukutshayela kwakho ukufumana igrafu phantsi kweekhrayitheriya ezithile onokuthi uzibeke. Oku kubizwa ngokuba yi-triggering. Ii-multimeters zeGraphical azinalo olu khetho kwaye ngenxa yoko, azinazo iintlobo ezahlukeneyo zokutshayela njenge-oscilloscopes. IiOscilloscopes zinceda kuphando ngenxa yesakhono sokuxhokonxa.
zekhusi
Ii-oscilloscopes zanamhlanje zinokuthatha umfanekiso weskrini wegrafu eboniswa kwisikrini, kwaye uyigcine elinye ixesha. Ayisiyiyo loo nto kuphela, loo mfanekiso unokugqithiselwa kwisixhobo se-USB. Akukho nanye kwezi mpawu ifumaneka kwi-multimeter. Eyona nto inokuyenza kukugcina ubukhulu bento.
yoGcino
Phakathi ukuya kwi-oscilloscopes ephezulu ayikwazi ukugcina imifanekiso kuphela, kodwa inokugcina iigrafu eziphilayo zexesha elithile. Eli nqaku alifumaneki kuyo nayiphi na i-graphing multimeter kwimarike. Ngenxa yeli nqaku, ii-oscilloscopes ziya zithandwa ngakumbi kwiinjongo zophando, njengoko zinokugcina idatha ethembekileyo yokufunda ixesha elizayo.
Ibala lokuSebenzisa
Iigrafim multimeter kwaye zinokusetyenziswa kuphela kwicandelo lobunjineli bombane. Kodwa ii-oscilloscopes ziyasetyenziswa kwicandelo lesayensi yezonyango ngaphandle kobunjineli bombane. Umzekelo, i I-oscilloscope inokusetyenziswa ukujonga ukubetha kwentliziyo yesigulana kunye nokufumana ulwazi oluxabisekileyo olunxulumene nentliziyo.
ixabiso
I-Oscilloscopes yindlela ebiza ngakumbi kune-graphing multimeter. Ii-Oscilloscopes zihlala ziqala ukusuka kwi- $ 200 ukuya phambili. Kwelinye icala, iigrafim multimeter zinokufumaneka ngexabiso eliphantsi njenge- $ 30 okanye i- $ 50.
Ukuyifumanisa
Ii-Oscilloscopes zineendlela ezininzi kunegrafim multimeter. Kwakhona, i-graphing multimeter ayisondeli nakwi-oscilloscope xa isiza kwizinto ezinokuzenza. Xa sele sithethile, asinakutsho ukuba i-oscilloscope ibetha i-multimeter kudidi ngalunye kwaye kuya kufuneka uthenge i-oscilloscope kuphela.
Ii-Oscilloscopes zenzelwe iinjongo zophando. Kuya kunceda ukufumana iimpazamo kwisekethe efuna amaza achanekileyo kunye novakalelo. Kodwa, ukuba injongo yakho kukufumana kuphela ubukhulu kunye nokujonga ukuba yintoni le fom wave, unokusebenzisa ngokulula i-graphing multimeter. Ayizukusilela kuloo nto.
Unokufunda: Uyisebenzisa kanjani i-Oscilloscope
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.
