Yintoni i-logic probe?
Omnye I-Logic probe sisixhobo esibalulekileyo sokusombulula ingxaki kwi-elektroniki yedijithali. Umsebenzi wayo ophambili kukubeka iliso kwi-voltage ekhoyo kwiindawo ezahlukeneyo kwisekethe, kwaye ibonise ukuba la manqaku akwizinga eliphezulu okanye eliphantsi lombane. Iprobe inokubona zombini amanqanaba ombane alungileyo kunye namabi. I-logic probe isetyenziselwa ukuxilonga iingxaki kwii-elektroniki zedijithali. Inokukunceda ukuba ufumane iimpazamo kwisekethe. Ikwaluncedo kwisoftware yokulungisa ingxaki, ukuchonga unxibelelwano olubi, kunye nokunceda uqonde indlela inkqubo ezenzekelayo okanye irobhothi esebenza ngayo. I-logic probe ingaba luncedo ukuba usebenza rhoqo kunye ne-microprocessors okanye enye i-digital control circuitry. Isetyenziselwa ikakhulu ukujonga i-voltage kunye namanqanaba akhoyo kumanqaku ahlukeneyo kwisekethe.
Ingaba i-logic probe isebenza njani?
I-logic probe inenxalenye yokuba itshintsha imeko yayo (0 okanye 1, TRUE okanye FALSE) xa i-voltage itshintsha kwindawo ethile kwisekethe. I-probe ineziqhagamshelo ezimbini, enye yegalelo kunye neyokuphuma. Igalelo lixhunywe kwindawo ye-voltage kunye nesiphumo kwisalathisi. Isalathiso seprobe sikhanyisa xa i-voltage kwi-probe input iguquka ukusuka ezantsi ukuya phezulu, okanye ukusuka phezulu ukuya phantsi. Xa i-voltage kwindawo egadiweyo iguquka, isiphaluka seprobe sivula okanye sivale. Olu tshintsho lwemeko lugqithiselwa kwimveliso yeprobe kwaye isalathisi seprobe sikhanyisa.
Kusetyenziswa ii-logic probes ukulawula amanqanaba ombane kwiisekethe izinto zombane. I-probe ineziqhagamshelo ezimbini, enye yegalelo kunye neyokuphuma. Igalelo leprobe lixhunywe kwindawo yombane kunye nesiphumo kwisalathisi. Xa i-voltage kwindawo ebekwe esweni itshintsha, isiphaluka seprobe sitshintsha isimo saso ukubonisa oku. Olu tshintsho lwemeko lugqithiselwa kwimveliso yeprobe, kwaye isalathisi seprobe sikhanyisa. Isalathisi kwiprobe ngokuqhelekileyo ukukhanya okanye i-LED. Isenokuba sisandi okanye intshukumo.
Yintoni ekufuneka uyiqwalasele xa uthenga i-logic probe?
Xa uthenga i-logic probe, qiniseka ukuba inokuwenza umsebenzi owufunayo. Iprobe oyikhethayo kufuneka ilungele isicelo sakho. Nika ingqalelo kwezi ngongoma zilandelayo:
- amanqanaba ombane: Iindidi ezahlukeneyo ze-logic probes zinokubeka iliso kumanqanaba ombane ahlukeneyo. Qinisekisa ukuthenga iprobe enokubeka iliso kumanqanaba ombane kwisekethe yakho.
- amanqanaba angoku: Iprobe yangoku ingasetyenziselwa ukulinganisa i-AC okanye i-DC currents. Qinisekisa ukuba uthenga iprobe yangoku enokulinganisa ukuhamba kwangoku kwisekethe yakho.
- Uhlobo lwengqiqo luyaxhaswa: Ii-Logic probes zinokuxhasa iindidi ezahlukeneyo zengqiqo, njenge-DTL, TTL, CMOS, njl. Qinisekisa ukuba ixhasa usapho lwezo ziphaluka ofuna ukuzivavanya.
- probe ubude: Qinisekisa ukuba uthenga i-logic probe yobude obufanelekileyo. Iiprobe ezimfutshane zilungele uvavanyo lwe-PCB, ngelixa ezinde zingasetyenziselwa ukuvavanya izihlanganisi kunye nezinye izixhobo.
Isetyenziswa njani i-logic probe?
Zininzi iindlela zokusebenzisa i-logic probe. Ungayisebenzisa ukuvavanya iisekethe, ukufumana izinto ezingalunganga, ukulandelela unxibelelwano olubi, kunye neengxaki zesoftware. Apha sichaza indlela yokwenza:
- Ukujonga isekethe: Ungasebenzisa i-logic probe ukuvavanya iisekethe ngokubeka iliso kumbane okhoyo kwiindawo ezahlukeneyo kwisekethe. Emva koko unokubona iingxaki ngokujonga utshintsho kwi-voltage yesiphaluka. Umzekelo, ungasebenzisa iprobe ukubona ukuba isekethe yedijithali isebenza njengoko kulindelekile. Unokujonga kwakhona ukuba isiphaluka sinikwe amandla ngokuchanekileyo.
- Fumana amalungu angalunganga: ungasebenzisa iprobe ukufumana izixhobo ezingalunganga ngokubeka esweni amandla ombane. Ngokomzekelo, i-probe ingasetyenziselwa ukujonga i-voltage ekuphumeni kwe-transistor. Ukuba imveliso ye-transistor ayinayo i-voltage elindelekileyo, usenokuba ufumene ingxaki.
- Ukulandela umdibaniso ongalunganga: Ungasebenzisa i-logic probe ukulandelela uxhulumaniso olubi ngokubeka iliso kwi-voltage kwiindawo kwisekethe. Ukuba ufumanisa ukuba i-voltage kwinqanaba elinye kwisekethe lihluke kwi-voltage kwindawo efanayo kwisekethe engummelwane, unokufumana uxhulumaniso olubi.
- Ukulungisa iingxaki kwiSoftware: Ungasebenzisa i-logic probe ukulungisa iingxaki zesoftware ngokubeka iliso kwi-voltage kwiindawo kwisekethe. Ukuba ufumanisa ukuba yonke into ibonakala ichanekile kwicala le-hardware, kunokwenzeka ukuba ukungasebenzi kakuhle kungenxa yesoftware.
Yintoni enokwenziwa i-logic probe monitor?
La Uxinzelelo kwiindawo ezahlukeneyo yesekethe yedijithali ingahluka ukusuka kwi-0 ukuya kwi-5 volts (phakathi kwezinye ii-voltages). Oko kukuthi, abo kunye no-zero, okanye iindawo eziphezulu kunye neziphantsi njengoko zibizwa ngokuba yi-elektroniki yedijithali. Kwakhona, khumbula ukuba iprobe inokubeka iliso kwimisinga ukuya kuthi ga kwi-amps ezili-10.
Ngokuqinisekileyo, unokujonga zonke uxinzelelo oluqhelekileyo yesekethe yedijithali. Oku kubandakanya amandla ombane obonelelo, amandla ombane omhlaba, amandla ombane aphezulu edijithali (i-VDH, ngokuqhelekileyo ii-volts ezi-5), i-digital low voltage (VDL, i-0 volts), kunye naluphi na umbane okhoyo kwisekethe ngenxa yangoku. I-probe ingasetyenziselwa ukubeka esweni i-voltage kwigalelo lesekethe ephilayo, i-voltage ekuphumeni kwesekethe, okanye i-current equkuqelayo kwisekethe. I-probe ingasetyenziselwa ukubeka esweni ii-voltages kwiisekethe zokwenziwa.
