Ufunani i-oscilloscope? Kubalulekile ukunquma ukuthi uzoyisebenzisela ini, njengoba i-oscilloscope yokuhlaziya amasekhethi edijithali ezingeni elinengqondo ayifani neyodwa ye-RF, noma ukuthi kufanele uyithuthe usuka endaweni ethile uye kwenye, njll. Ngaphezu kwalokho, kubalulekile futhi ukunquma ukuthi uyifunela ukusetshenziswa kochwepheshe noma ukusetshenziswa kokuzilibazisa. Esimweni sokuqala, kufanelekile ukutshala imali eyengeziwe ukuze uthole umshini ochwepheshile futhi onembe kakhudlwana. Esimweni sesibili, kungcono ukukhetha into enenani eliphakathi nendawo.
Ibhajethi: ukwazi ukuthi unemali engakanani ongatshala kuyo imishini yakho kuzokusiza ukuthi ukhiphe amamodeli amaningi angaphandle kwesabelomali futhi kuzonciphisa ububanzi bamathuba.
Umkhawulokudonsa (Hz): Inquma ububanzi bezimpawu ongazikala. Kufanele ukhethe i-oscilloscope enomkhawulokudonsa owanele ukuze uthwebule ngokunembile amaza amasiginali ozobe usebenza ngawo. Khumbula umthetho we-5, okuwukukhetha i-oscilloscope, kanye ne-probe, inikeza okungenani izikhathi ezingu-5 ubukhulu bomkhawulokudonsa wesiginali ojwayele ukuyikala ukuze uthole imiphumela engcono kakhulu.
Isikhathi sokuvuka (= 0.35/Umkhawulokudonsa): Kubalulekile ukuhlaziya ama-pulses noma amagagasi ayisikwele, okungukuthi, amasignali edijithali. Uma ishesha, izilinganiso zesikhathi zinembe kakhulu. Kufanele ukhethe izikophu ezinezikhathi zokukhuphuka ezingaphansi kwezikhathi ezingu-1/5 zesikhathi sokukhuphuka esisheshayo sesignali ozoyisebenzisa.
phenya: Kunamanye ama-oscilloscope anama-probe amaningana akhethekile ezimfuneko ezahlukene. Iningi lama-oscilloscopes anamuhla ngokuvamile liza nama-impedance passive probes aphezulu kanye nama-probe asebenzayo okulinganisa imvamisa ephezulu. Ngobubanzi obuphakathi kungcono ukukhetha ama-probe anemithwalo ye-capacitive engu-<10 pF.
Izinga lesampula noma imvamisa (Amasampuli we-Sa/so ngomzuzwana): izonquma ukuthi zingaki izikhathi lapho imininingwane noma amanani egagasi azolinganiswa athwetshulwa ngeyunithi yesikhathi. Uma iphezulu, ingcono ukulungiswa futhi izosebenzisa inkumbulo ngokushesha. Kufanele ukhethe i-oscilloscope enezikhathi okungenani ezi-5 kunemvamisa ephezulu kakhulu yesekethe ozoyihlaziya.
Ukwenza kusebenze noma ukucupha: Okuhle kakhulu uma inikeza izibangeli ezithuthuke kakhulu zamagagasi ayinkimbinkimbi. Uma kungcono, uzokwazi ukubona izinto ezididayo okunzima ukuzithola.
Ukujula kwenkumbulo noma ubude berekhodi (amaphoyinti): Okuningi, ukulungiswa okungcono kwamasignali ayinkimbinkimbi. Ibonisa inani lamaphoyinti angagcinwa kumemori, okungukuthi, amandla okugcina imiphumela yangaphambilini ngenkathi kwenziwa ukuhlola. Inani lokufundwayo lingarekhodwa futhi wonke amanani angabonwa ukuze afinyelele iziphetho ezinembe kakhudlwana noma alandelelwe.
Inani leziteshi: Khetha i-oscilloscope enenombolo efanele yamashaneli, iziteshi eziningi, imininingwane eyengeziwe ingatholwa. I-analog yayivame ukuba yiziteshi ezi-2 kuphela, kuyilapho ezidijithali zingasuka ku-2 kuya phezulu.
Isikhombi: Kufanele kube ngendlela enembile futhi elula ngangokunokwenzeka, ikakhulukazi uma usaqala. Amanye ama-oscilloscope athuthukile afanele kuphela ochwepheshe, njengoba umsebenzisi onolwazi oluncane angadinga ukufunda njalo imanuwali.
I-analog vs digital: ezidijithali okwamanje zikhonya emakethe ngenxa yezinzuzo zazo, njengokuvumela kalula, futhi ngaphandle kwemikhawulo kubude berekhodi. Ngakho-ke, inketho ekhethwayo kufanele nakanjani ibe i-oscilloscope yedijithali cishe kuwo wonke amacala.
Imikhiqizo: Imikhiqizo ye-oscilloscope ehamba phambili i-Siglent, i-Hantek, i-Rigol, i-Owon, i-Yeapook, njll. Ngakho-ke, ukuthenga enye yamamodeli abo kuzoba isiqinisekiso sokusebenza okuhle nekhwalithi.
