Pakati pemazana ezvekushandisa zviripo pamusika wekuyera ruzivo pane imwe magetsi chiratidzo, maviri emachina akajairika ndiwo multimeter uye oscilloscope. Asi ivo vakapfuura nemukuchinja kukuru pamusoro pemakore kuti vave nani uye vabudirire pabasa ravo.
Kunyangwe iro basa remidziyo miviri iri rakada kufanana, ivo havana kufanana zvese maererano nekushanda uye kutaridzika. Ivo vane zvimwe zvakasarudzika maficha izvo zvinoita kuti ivo vasarudzika kune mamwe minda. Isu tinokuudza mutsauko wese uripo pakati pemidziyo miviri iyi kuti uzive kuti ndeipi ichakubatsira zvakanyanya pasi pemamiriro akasiyana.
Kusiyanisa iyo Oscilloscope kune Graphing Multimeter
Kana iwe uchida kutsvaga mutsauko uripo pakati pezvinhu zviviri, iwe unongofanirwa kuenzanisa maficha avo uye uone kuti ndeipi inoita basa riri nani kune rimwe basa. Uye ndizvo chaizvo zvatakaita pano. Takaita ongororo yakadzama uye takadzidza pane izvo zvinhu zvinomisikidza michina miviri iyi, uye takanyora izvo pasi zvako pazasi.
Nhoroondo yeKusika
Nepo mudziyo wekutanga wekufambisa-wekugadzira wakagadzirwa yaive galvanometer muna 1820, yekutanga multimeter yakagadzirwa mukutanga kwema1920. British Post Office injinjini Donald Macadie akagadzira muchina uchinetsekana nekudiwa kwekutakura akawanda madivayiri anodikanwa ekuchengetedza materevhizheni maseketi.
Yekutanga oscilloscope yakagadzirwa muna 1897 naKarl Ferdinand Braun, uyo akashandisa iyo Cathode Ray Tube (CRT) kuratidza kushandurwa kweye anogara achifamba musarudzo anomiririra chimiro chechiratidzo chemagetsi. Mushure mehondo yechipiri yenyika, makitsi eoscilloscope akawanikwa pamusika kweinosvika madhora makumi mashanu.
Bandwidth
Low-end oscilloscopes ine yekutanga bandwidth ye1Mhz (MegaHertz) uye inosvika kune mashoma MegaHertz. Kune rimwe divi, graphing multimeter ine bandwidth ye1Khz (KiloHertz) chete. Kuwedzera bandwidth yakaenzana nekuwanda kwescans pasekondi iyo inoguma neyakajeka uye chaiwo waveforms.
Maonero: Saizi uye Basic Zvikamu
Oscilloscopes akareruka uye anotakurika zvigadzirwa zvinoita kunge diki bhokisi. Kunyangwe paine zvimwe zvakakosha chinangwa zviyero zvine rack-zvakaiswa. Girafu multimeter, kune rumwe rutivi, idiki zvakakwana kutakura muhomwe yako.
Iwo maitirwo uye iyo skrini iri kuruboshwe uye kurudyi divi reoscilloscope. Mune oscilloscope, iyo saizi saizi yakakura kwazvo kana ichienzaniswa neiyo diki skrini ye graphing multimeter. Iyo skrini inovhara nezve 50% yemuviri wechigadzirwa mune oscilloscope. Asi pane graphing multimeter, inenge 25%. Zvimwe zvese ndezvekutonga uye zvekushandisa.
Screen Zvivakwa
Oscilloscope screens ari makuru nzira kupfuura iyo ye graphing multimeter. Pane iyo skrini yeiyo oscilloscope, pane grid ine zvidiki zvikwere zvinozivikanwa semadivisi. Izvi zvinopa kuita kwakasiyana siyana uye kushanduka senge girafu chairo. Asi hapana grid kana zvikamu mu graphing multimeter's skrini.
Zviteshi zveInput Jacks
Kazhinji, pane maviri ekupinza chiteshi pane oscilloscope. Chiteshi chega chega chekupinza chinogamuchira chiratidzo chakazvimirira uchishandisa ma probes. Mune graphing multimeter, kune matatu ekupinza madoko akanyorwa COM (zvakajairika), A (yezvazvino), uye V (yemagetsi). Iko kune zvakare chiteshi chekunze chinokonzeresa mune oscilloscope iyo isipo pane graphing multimeter.
anotonga
Iwo maitirwo mune oscilloscope akapatsanurwa kuita zvikamu zviviri: iyo yakatwasuka uye yakatwasuka. Chikamu chakatwasuka chinodzora hunhu hweiyo X-axis yegirafu yakaumbwa pachiratidziri. Chikamu chakamira chinodzora Y-axis. Nekudaro, hapana masimba ekudzora girafu mune graphing multimeter.
Iko kune dial hombe mune graphing multimeter iwe yaunofanirwa kutendeuka wonongedzera kuchinhu iwe chaunoda kuyera. Semuenzaniso, kana iwe uchida kuyera mutsauko wemagetsi, saka unofanirwa kudzosera dial ku "V" yakamisikidzwa pakakomberedza dial. Aya maitirwo ari padyo nechidzitiro cheoscilloscope, pamberi chaipo pechikamu chakamira.
Mune graphing multimeter, iyo yakasarudzika kuburitsa ndiyo kukosha. Kuti uwane girafu, unofanirwa kubaya pane "Auto" bhatani pazasi pechidzitiro. Oscilloscopes inokupa girafu nekukasira. Iwe unogona kuwana rumwe ruzivo pane iyo girafu uchishandisa mapfundo pane iyo yakatwasuka uye chikamu chakatwasuka pamwe nepaneru iri padyo nechidzitiro.
Mabhatani ekubata kukosha uye kuburitsa kukosha kwemiedzo mitsva inowanikwa iko chaiko mushure me "Auto" bhatani. Mabhatani ekuchengetedza mhedzisiro mune oscilloscope anowanzo kuwanikwa pamusoro peiyo chikamu chakamira.
Mhando dzekutsvaira
In oscilloscope, unogona kugadzirisa kutsvaira kwako kuti uwane girafu pasi pemaitiro chaiwo aunogona kuseta. Izvi zvinonzi triggering. Graphical multimeters haina iyi sarudzo uye semhedzisiro, ivo havana akasiyana marudzi ekutsvaira senge oscilloscopes. Oscilloscopes anobatsira mukutsvaga nekuda kwekugona kukonzeresa.
Screenshots
Mazuva ano oscilloscopes anogona kutora skrini yemifananidzo yegirafu iri kuratidzwa pachiratidziri, uye ichichengetera imwe nguva. Kwete izvozvo chete, mufananidzo iwoyo unogona kuendeswa kune USB mudziyo zvakare. Hapana chimwe chezvimiro izvi inowanikwa mune multimeter. Iyo yakanakisisa yainogona kuita kuchengeta ukuru hwechimwe chinhu.
chengetedzo
Pakati kusvika kumusoro-kumagumo oscilloscopes anokwanisa kuchengeta kwete chete mifananidzo, asi ivo vanogona zvakare kuchengeta mhenyu mairafu eimwe imwe nguva muganho. Ichi chimiro hachiwanikwe pane chero graphing multimeter kunze pamusika. Nekuda kwechinhu ichi, maoscilloscopes ari kuve anozivikanwa zvakanyanya nekuda kwekutsvagisa, sezvo vachigona kuchengeta data rakaomarara rekufunda mune ramangwana.
Munda weKushandisa
Graphing multimeter ari uye anogona chete kushandiswa mumunda weinjiniya yemagetsi. Asi oscilloscopes ari kushandiswa mumunda wesainzi yekurapa kunze kwemagetsi enjiniya. Semuenzaniso, an oscilloscope inogona kushandiswa kuona kurova kwemoyo kwemurwere uye kuwana ruzivo rwakakosha rwakanangana nemoyo.
mutengo
Oscilloscopes ndiyo nzira inodhura zvakanyanya kupfuura graphing multimeter. Oscilloscopes inowanzotanga kubva pamadhora mazana maviri zvichienda mberi. Kune rimwe divi, graphing multimeter inogona kuwanikwa yakachipa kunge $ 200 kana $ 30.
Kuti Sum Sum Up
Oscilloscopes ine nzira dzakawanda maficha pane graphing multimeter. Zvakare, graphing multimeter haina kana kusvika padhuze neiyo oscilloscope kana zvasvika pazvinhu zvayingaite. Nezvo zvataurwa, hatigone kutaura kuti oscilloscope inorova iyo multimeter mune yega yega chikamu uye iwe unofanirwa kungotenga oscilloscope.
Oscilloscopes ndeyekutsvagisa zvinangwa. Izvo zvinobatsira kuwana zvikanganiso mudunhu zvinoda chaiwo uye akaomarara mafungu. Asi, kana chinangwa chako chiri chekungowana kumwe kukura uye wotarisa kuti chii chinonzi waveform, saka unogona kushandisa nyore nyore graphing multimeter. Hazvizokundikane iwe mune izvo.
