Mashiinka baakaynta isku-dhafka tijaabada wareegga, ugu weyn waa inuu cabbiraa dhibcaha imtixaanka muhiimka ah.
Habka guud waa in la isticmaalo tijaabinta qalabka cagaha kasta oo lugaha iyo pin si ay dhulka iska caabin ah, gelinta iyo danab wax soo saarka, isticmaalka tamarta iyo galinta / wax soo saarka waveform, iyo natiijada imtixaanadu ka duwan yihiin xuduudaha wareegga isku dhafan ee caadiga ah, xukumi kara wareegga isku dhafan in la tijaabiyo waa caadi.
gudaha
mashiinka baakadaha, Microprocessors-ka wareegga isku-dhafan ee caadi ahaan loo isticmaalo, wareegga isku-dhafan ee filimka dhumuc weyn leh iyo beddelka qalabka korontada ku shaqeeya ee IC.
Aynu si faahfaahsan arrimahan u falanqeyno.
mashiinka baakadaha Tijaabada isku-dhafan ee furaha dhibcaha tijaabada wareegga isku dhafan.
1.
Furaha barta tijaabada wareegga isku dhafan ee microprocessor
Furaha microprocessor-ka isku-dhafka ah ee tijaabada wareegga inta badan waa dhinaca awoodda VDD, RESET, RESET, crystal IN signal vibration input, Xor crystal wax soo saarka calaamadda gariirka dhamaadka soo-gelinta, soo-saarka, iyo wareegyada kale.
tijaabinta internetka waxay cabbirtaa barta muhiimka ah ee iska caabbinta iyo qiimaha danab iyo caadiga ah waxay xukumi kartaa wareegga isku dhafan waa caadi;
2.
Furaha korantada wareejinta barta IC
Furaha wareejinta korantada IC barta tijaabada inta badan waa Vc dhamaadka gelinta, danab, gelinta ogaanshaha hadda, wax soo saarka garaaca, iwm.
imtixaanka online waxaa loo isticmaalay in lagu cabbiro danab isku dhafan ee isku dhafan iyo iska caabinta pin kasta, ka dibna la barbar dhigo xogta ku saabsan caadiga ah, sida farqiga weyn, sidoo kale waa in la tijaabiyo qayb la xidhiidha, qayb waxaa lagu go'aamiyaa hoos xaaladda caadiga ah, xukumi karaa wareegga isku dhafan waa la dhaawacay.
Tuubbada wareejinta isku-dhafan ee isku-dhafan waa qaybta udub-dhexaadka ah, filimka dhumucda leh ee isku dhafan ee isku-dhafan ee tuubbada wareejinta awoodda weyn marka aysan fiicneyn in la shakiyo tuubada wareejinta waxaa lagu qiyaasi karaa iyadoo la beddelayo tube c, b, e aad u dhexeeya caabbinta hore iyo gadaal. xukun.
3.
Qalabka muhiimka ah ee cod-weyneeye IC barta tijaabada
furaha cod-weyneeyeha hawlgalka IC barta tijaabada inta badan waa gelinta iyo soo saarista.
Bartan qiimaha danabka taagan ayaa ka sarreeya.
tijaabi, multimeter-ka ilaa dc danab, cabbiraya qiimaha danab soo saarka u dhexeeya dhamaadka iyo dhamaadka korontada taban.
Iyada oo leh maroojiyeyaasha birta ah ee gacanta, iyaguna, taabashada labada gelinta ee dhamaadka cod-weyneeye (
Ku biir calaamada jaamamka)
, oo fiirso xaalada oscillation saacada, caadi ahaan, tilmaamayaasha multimeter-ka ayaa yeelan doona luxul weyn, sida tilmaame oo aan dhaqaaqin, ka dib cod-weyneeye hawleedka ayaa dhaawac gaadhay.
4.
Baaskiil koronto oo gaar ah oo isku dhafan oo tijaabo ah.
Mashiinka baakadaha, inta badan la isticmaalo 555 saldhiga isku dhafan ee wareegga wareegga TL494 iyo wareegga.
Aynu si gaar ah u eegno qodobada muhiimka ah ee hababka tijaabada gaarka ah (
1)
Go'aaminta wareegga isku dhafan ee T494
mashiinka wax lagu xidho ee isku dhafan tijaabada wareegga si loo go'aamiyo isku-dhafka isku-dhafka ah ee T494 ee tallaabooyinka sida soo socota.
1)
Diyaarso qalab.
Tijaabinta wareegyada isku dhafan si loo doorto hawlo badan, sida multimeter-ka dhijitaalka ah, moodooyinka leh MY68 nooca la taaban karo iyo nooca MS820 multimeter-ka dhijitaalka ah.
waxay ogaan karaan inta jeer ee 150 KHZ iyo 200 KHZ.
Waxa kale oo aad u baahan tahay oscilloscope, dabaylo silig iska caabin ah oo la hagaajin karo, iwm.
2)
Cabbirka soo noqnoqda oscillation.
Multimeter-ka ugu horreeya ee isku xira ilaa 200 KHZ, heerka sahaminta hordhaca ah ee T494
Wareegyada kale ee isku dhafan sida ka hooseeya 200 Hz, waxay hagaajin karaan qalabka)
, si loo saxo.
T494 oscillation ee 5, iyo 6 cagood, sidaas darteed qalinka multimeterka iyo labadan cagood, waxay go'aamin karaan mowjadda sawtooth.
Xakamaynta iyo xakamaynta wareegga wareegga oscillation ee 20 ~ 80 kh, natiijooyinka go'aaminta waa qiimo gaar ah, wareegga wareegga isku dhafan waa mid caadi ah, qiimaha awoodda caabbinta waa sax.
haddii aysan jirin calaamado gariir, waa in ay fiiriyaan barta xiriirka iyo qalimaan, fiilooyinka, iwm.
Haddii dib-u-eegista ay weli ka yar tahay cabbirka tirooyinka wareegga isku-dhafan ayaa dhibaato leh.
haddii inta jeer ee aan la ogolayn, u sheegaya Rr ama Cr, xaaladda muuqaalka hagaajinta habboon ama beddelka.
3)
Cabbiraadda saamiga waajibaadka
U diyaarsan oscilloscope, T494 wuxuu soo saari doonaa pin 9, 10, wuxuu isku xiri doonaa interface interface oscillograph, oo u sii gudbi 9, 10 cagood iyo culeyska la qiimeeyay.
Halkan waxaa muhiim ah in la ogaado in aan lahayn culeys la qiimeeyay, saamiga waajibaadku maaha cabbir sax ah, oo ka soo jeeda qiimaha naqshadda asalka ah.
U fiirso oscilloscope 9, 10 cagood oo ah waveform-ka soo-saarka, isla markaana hagaaji saamiga waajibaadka: si aad u xakamayso curiyaha, hagaajiso xawliga habaynta xakame, by 0 spin;
Dabaylaha, hagaaji qiimaha iska caabinta 0 ilaa 6 cagood (
Awoodda C, isla markaana hagaajiso)
.
Waqtigaan laga bilaabo oscilloscope-ka waa in lagu arko saamiga waajibaadka oo ka beddelaya eber ilaa boqol boqol oo kala duwan.
Mashiinka baakadaha isku-dhafka ah ee isku-dhafka ah waa mid caadi ah ama ma aha mid la xidhiidha mishiinka hawlgalka caadiga ah, markaa waa muhiim, waxaan rajeynayaa in maqaalkani mashiinka baakadaha isku-dhafka ah ee isku-dhafka ah uu ku caawinayo adiga.
Mar kasta oo su'aasha mashiinka miisaamiyaha la kiciyo, mid ayaa ka soo baxa ereyga ''.
