Umshini wokupakisha ukuhlolwa kwesifunda okuhlanganisiwe, okuyinhloko kufanele kube ukukala amaphuzu okuhlola abalulekile.
Indlela evamile ukusebenzisa ukuhlola ithuluzi wonke ama-voltage onyawo kanye nokuphina ukumelana nomhlabathi, i-voltage yokufaka neyokukhiphayo, ukusetshenziswa kwamandla kanye ne-oput/output waveform, kanye nemiphumela yokuhlola ihluke namapharamitha esekethe ahlanganisiwe ajwayelekile, ingahlulela isekethe ehlanganisiwe okufanele ihlolwe evamile.
kwe
umshini wokupakisha, ama-microprocessors esekethe ahlanganisiwe asetshenziswa kakhulu, isekethe edidiyelwe yefilimu ewugqinsi kanye nokushintsha amandla okusebenza kweamplifier IC.
Ake sihlaziye kabanzi ngalokhu.
umshini wokupakisha ukuhlolwa kwesifunda okuhlanganisiwe kukhiye wamaphoyinti okuhlola amasekethe ahlanganisiwe.
1.
Ukhiye wephoyinti lokuhlola lesekethe elihlanganisiwe le-microprocessor
ukhiye wephoyinti lokuhlola lesifunda elihlanganisiwe le-microprocessor ngokuyinhloko uhlangothi lokuphakelwa kwamandla e-VDD, UKUSETHWA KABUSHA, UKUSETHWA KABUSHA, okokufaka kwesignali ye-crystal IN yokudlidliza, ukuphela kokuphumayo kwesignali yokudlidliza kwe-Xor kokokufaka, okukhiphayo, namanye amasekhethi.
ukuhlolwa kwe-inthanethi ukulinganisa iphuzu eliyinhloko lokumelana nenani le-voltage futhi okuvamile kungahlulela isifunda esihlanganisiwe sivamile;
2.
Ukhiye wephoyinti lokuhlola le-IC yokushintsha amandla kagesi
isihluthulelo sephoyinti lokuhlola le-IC elishintshayo liwukuphela kokufaka kokutholwa kwe-Vc, i-voltage, okokufaka kokutholwa kwamanje, ukuphuma kwe-pulse, njll.
ukuhlolwa okuku-inthanethi kwasetshenziselwa ukukala i-voltage ehlanganisiwe yesifunda kanye nokumelana kwephini ngalinye, bese kuqhathaniswa nedatha evamile, njengomehluko omkhulu, kufanele futhi kube ingxenye ehlobene nokuhlola, ingxenye inqunywa ngaphansi kwesimo esivamile, ingahlulela Isifunda esihlanganisiwe sonakalisiwe.
Kushubhu lokushintsha elihlanganisiwe lesifunda liyingxenye eyinhloko, isifunda esihlanganisiwe sefilimu esakhelwe ngaphakathi seshubhu enkulu yokushintsha amandla lapho kungalungile ukungabaza ishubhu yokushintsha ingalinganiswa ngokushintsha ishubhu c, b, e kakhulu phakathi kokumelana nokuya phambili nokuhlehlayo. ekwahlulelweni.
3.
Iphoyinti lokuhlola le-IC ye-amplifier yokusebenza engukhiye
ukhiye wephoyinti lokuhlola le-IC yeamplifier ngokuyinhloko okokufaka nokukhiphayo.
Leli phuzu levelu ye-voltage emile liphezulu.
test, i-multimeter kuya ku-dc voltage, ukulinganisa inani le-voltage ephumayo phakathi kokuphela nokuphela kokunikezwa kwamandla okungekuhle.
Ngama-tweezers ensimbi esandla, wona, ethinta isiphetho sokufakwayo okubili kwe-amplifier yokusebenza (
Joyina isignali ye-jamming)
, futhi ubuke isimo se-oscillation yewashi, evamile, i-multimeter pointer izoba ne-oscillation enkulu, njengokuthi i-pointer ayinyakazi, khona-ke i-amplifier yokusebenza yonakalisiwe.
4.
Ukuhlolwa kwephoyinti lesifunda elihlanganisiwe lebhayisikili likagesi.
emshinini wokupakisha, isifunda se-555 sesikhathi esihlanganisiwe se-TL494 esivame ukusetshenziswa.
Ake sibheke ngokuqondile amaphuzu abalulekile ezindlela ezithile zokuhlola (
1)
Ukunqunywa kwesekethe ehlanganisiwe ye-T494
umshini wokupakisha ukuhlolwa kwesifunda okudidiyelwe ukuze kunqunywe isifunda esihlanganisiwe T494 ngezinyathelo ezilandelayo.
1)
Lungiselela insimbi.
Ukuhlolwa kwamasekethe ahlanganisiwe ukuze kukhethwe imisebenzi eyengeziwe, efana ne-digital multimeter, amamodeli anohlobo olusebenzayo lwe-MY68 kanye nohlobo lwe-multimeter yedijithali ye-MS820.
bayakwazi ukubona imvamisa ka-150 KHZ no-200 KHZ.
Futhi udinga i-oscilloscope, i-adjustable resistance wire winding, njll.
2)
Isilinganiso se-oscillation frequency.
I-screw multimeter yokuqala ukuya ku-200 KHZ, inhlolovo yokuqala ye-T494 oscillation rate (
Komunye umjikelezo ohlanganisiwe onjengangaphansi kuka-200 hz, ungalungisa igiya)
, ukuze wenze ngokunembile.
I-T494 oscillation ku-5, kanye nezinyawo ezingu-6, ngakho-ke amapeni e-multimeter nakulezi zinyawo ezimbili, angakwazi ukunquma igagasi le-sawtooth.
Ishaja kanye nesifunda sokulawula imvamisa ye-oscillation ye-20 ~ 80 kh, imiphumela yokunquma inenani elithile, i-oscillation yesifunda ehlanganisiwe ijwayelekile, inani le-capacitance yokumelana lilungile.
uma kungekho zimpawu ze-oscillation, kufanele ahlole indawo yokuxhumana namapeni kanye, izintambo, njll.
Uma ukuhlolwa kabusha kusengaphansi kokukalwa kwezinombolo kwesekethe ehlanganisiwe kunenkinga.
uma i-frequency ingavunyelwe, ukutshela i-Rr noma i-Cr, isimo sokubukwayo ukulungiswa okufanele noma ukushintshwa.
3)
Ukulinganisa isilinganiso somsebenzi.
Ilungele i-oscilloscope, izokhipha iphinikhodi ye-T494 engu-9, 10, ixhume isixhumi esibonakalayo se-oscillograph, futhi ithuthukele ku-9, 10 wamafidi nomthwalo olinganiselwe.
Lapha kubalulekile ukuqaphela ukuthi akukho mthwalo olinganiselwe, isilinganiso somsebenzi akusona isilinganiso esinembile, sisuka enanini lomklamo wokuqala.
Qaphela i-oscilloscope engu-9, 10 izinyawo ze-waveform okukhiphayo, ngesikhathi esifanayo lungisa isilinganiso somsebenzi: ukulawula isici, lungisa isibambo esilawula isivinini, ngo-0 spin;
Ishaja, lungisa inani lokumelana ukusuka ku-0 kuye ku-6 wamafidi (
I-capacitance C, ngesikhathi esifanayo lungisa)
.
Ngalesi sikhathi kusukela ku-oscilloscope kufanele ubone izinguquko zesilinganiso semisebenzi ukusuka ku-zero ukuya kububanzi bamaphesenti ayikhulu.
umshini wokupakisha umjikelezo ohlanganisiwe ujwayelekile noma cha uhlobene nomshini ungasebenza okuvamile, ngakho-ke kubalulekile, ngithemba ukuthi lesi sihloko somshini wokupakisha ukuhlolwa kwesifunda esihlanganisiwe siwusizo kuwe.
Noma nini lapho umbuzo womshini wokukala uphakanyiswa, umuntu uhlangabezana negama elithi ''.
