indlela yokukhetha

Ngexesha le khetha i-oscilloscope elungileyo, kufuneka uthathele ingqalelo ezinye zezi mpawu zilandelayo. Ngale ndlela, uya kuba nakho ukukhetha eyona ilungileyo kwaye ilungele ukusetyenziswa kwakho:

  • Ufuna ntoni i-oscilloscope? Kubalulekile ukumisela ukuba uza kuyisebenzisela ntoni na, kuba i-oscilloscope yokuhlalutya iisekethe zedijithali kwinqanaba le-logic ayifani ne-RF, okanye kufuneka uthuthe ukusuka kwenye indawo ukuya kwenye, njl. Ukongeza, kukwabalulekile ukufumanisa ukuba uyayifuna ukuba isetyenziswe ngobuchwephesha okanye kusetyenziso lokuzonwabisa. Kwimeko yokuqala, kufanelekile ukutyala imali kancinci ngakumbi ukuze ufumane isixhobo sobuchwephesha kunye nesichanekileyo. Kwimeko yesibini, kungcono ukhethe into enexabiso eliphakathi.
  • Bhajethi: ukwazi ukuba ungakanani utyalo-mali kwisixhobo sakho kuya kukunceda ulawule iimodeli ezininzi ezingaphandle kwebhajethi kwaye ziya kunciphisa uluhlu olunokwenzeka.
  • Ububanzi (Hz): Imisela uluhlu lweempawu onokuthi uzilinganise. Kuya kufuneka ukhethe i-oscilloscope ene-bandwidth eyaneleyo yokubamba ngokuchanekileyo ezona zihlandlo ziphezulu zeempawu oza kusebenza nazo. Khumbula umgaqo we-5, okukukhetha i-oscilloscope, kunye ne-probe, inikezela ubuncinane ngamaxesha angama-5 ubuninzi be-bandwidth yesiginali odla ngokuyilinganisa ngeziphumo ezilungileyo.
  • Ixesha lokunyuka (= 0.35/Bandwidth): Kubalulekile ukuhlalutya i-pulses okanye amaza angama-square, oko kukuthi, iimpawu zedijithali. Okukhona ikhawulezayo, kokukhona ichaneka ngakumbi imilinganiselo yexesha. Kuya kufuneka ukhethe imida enamaxesha okunyuka angaphantsi kwe-1/5 amaxesha elona xesha likhawulezayo lokunyuka kophawu oza kulisebenzisa.
  • probes: Kukho ezinye ii-oscilloscopes ezineprobe ezininzi ezikhethekileyo kwiimfuno ezahlukeneyo. Uninzi lwee-oscilloscopes zanamhlanje ngokuqhelekileyo ziza ne-impedance passive probes ephezulu kunye ne-probes esebenzayo yemilinganiselo ephezulu yefrikhwensi. Kuluhlu oluphakathi kungcono ukhethe iiprobes kunye nemithwalo ye-capacitive <10 pF.
  • Ireyithi yesampulu okanye amaxesha amaninzi (Sa/so Samples ngeSekondi): iya kugqiba ukuba mangaphi amaxesha iinkcukacha okanye amaxabiso amaza aya kulinganiswa afakwe kwiyunithi yexesha. Iphezulu, ngcono isisombululo kwaye ngokukhawuleza iya kusebenzisa imemori. Kuya kufuneka ukhethe i-oscilloscope enobuncinci amaxesha ama-5x elona xesha liphezulu lesekethe oya kuyihlalutya.
  • Ukuqalisa okanye ukuxhokonxa: Eyona nto ingcono ukuba inikezela ngezivuseleli eziqhubela phambili ngakumbi kwiifom zamaza ezintsonkothileyo. Okukhona kungcono, kokukhona uya kukwazi ukubona izinto ezingaqhelekanga ekunzima ukuzifumana.
  • Ubunzulu benkumbulo okanye ubude berekhodi (iipt): Okukhona, isisombululo esingcono kwiimpawu ezinzima. Ibonisa inani lamanqaku anokugcinwa kwinkumbulo, oko kukuthi, amandla okugcina iziphumo zangaphambili ngelixa usenza umfuniselo. Inani lokufundwa linokurekhodwa kwaye onke amaxabiso anokubonwa ukwenza izigqibo ezichanekileyo okanye ukulandelela.
  • Inani leendlela: Khetha i-oscilloscope enenani elifanelekileyo lamatshaneli, amajelo amaninzi, iinkcukacha ezininzi zinokufunyanwa. I-analog isetyenziselwa ukuba ibe ngamajelo e-2 kuphela, ngelixa i-digital ingahamba ukusuka kwi-2 ukuya phezulu.
  • Ujongano: Kufuneka kube lula kwaye kube lula, ngakumbi ukuba ungumqali. Ezinye ii-oscilloscopes eziphucukileyo zilungele kuphela iingcali, kuba umsebenzisi onamava angafunekiyo afunde rhoqo le ncwadana.
  • I-Analogs yedijithali: iidijithali okwangoku zilawula kwimarike ngenxa yeenzuzo zazo, ezifana nokuvumela ukukhululeka okukhulu, kwaye ngaphandle kwemida kubude berekhodi. Ke ngoko, ukhetho olukhethiweyo kufuneka lube yi-oscilloscope yedijithali phantse kuzo zonke iimeko.
  • Iimpawu: ezona mpawu zeoscilloscope zibalaseleyo yiSiglent, Hantek, Rigol, Owon, Yeapook, njl. Ngoko ke, ukuthenga enye yeemodeli zabo kuya kuba sisiqinisekiso sokusebenza kakuhle kunye nomgangatho.
