Indlela ukwenza oscilloscope ukusuka ikhadi lesandi

Wonke radio engahlawulwayo kufuneka ibe ifowuni, njenge oscilloscope zaselebhu yakhe ekhaya. Yena kufuneka ukulungisa nokulungelelanisa iintambo zobuchwepheshe. Ngapha koko, ngaphandle wathi isixhobo akuthethi ukuphatha isifundo iziphaluka ezitsha kunye neempawu zazo. Nakuba kunjalo, iindleko oscilloscope lwedijithali kunye analog kakhulu eliphezulu. Kwakhona zama ukufumana isixhobo ezisetyenziswayo, kodwa ke ezi zixhobo ukuba wonke ipokotho. Eli nqaku sigxile indlela yokwenza oscilloscope ukusuka ikhadi lesandi. Ixabiso kokulungiswa enjalo ayinamsebenzi, kuba sisiseko isixhobo uthe uthatha i-PC inxenye. Ukuze ukubonisa amaza usebenzisa software eyodwa.

Oscilloscope sound ikhadi: izinto eziluncedo nezingeloncedo

Izinto eziluncedo ze isixhobo ethathelwa ingqalelo ziquka ngendleko ephantsi, Kakade ke, ngaphandle ye computer ngokwayo. Ngoku kubakho iingxaki. Ekuqaleni: Kuya kuba ngaphezu komvuzo apho. Luncedo, nto leyo lubonakala ngokuba oscilloscope ukusuka ikhadi lesandi - oku uvakalelo oluphezulu kakhulu. Usabela kwesa erediyo, nto leyo amaza kunokuba iimpazamo. Esi sithintelo yesibini kukuba nojongano ngegalelo lo ikhadi lesandi ikwazi ukuxhasa awo uphawu ayidluli 2 V. Oku kuthetha ukuba ikhadi ingonakaliswa lula. Le ngxaki kufuneka kuqwalaselwe eyimveliso zombini. Le oscilloscope le ikhadi lesandi lingenako umlinganiselo DC ombane.

Indlela yokwenza i kagesi

Okokuqala, kufuneka ukuba uyithathele ingqalelo inqanaba igalelo lwe ikhadi lesandi, amaxesha amaninzi akunjalo volts angapha kwesibini, kwaye kwezinye iibhodi - ngaphantsi kwe volt enye. Ngokuqhelekileyo, bekuya kuba zaneleyo kuba umlinganiselo le awo. Oku kufuna i-adaptha eya kuvumela ukwandisa imida ye awo umqondiso. Software - oscilloscope - uye imilinganiselo emibini kuvumelekile level: 12.5 V no 250 V. umzobo wesakhiwo esi sixhobo siqulathe iziqalelo ezintandathu kuphela - resistors. R1 R2 na resistance ngegama 1.5 Mohm, R3 ne R4 - 75 ohms, R5 kunye R6 - 1,5 kohm. resistors Power ukusasaza kufuneka bungabi ngaphantsi kwe-0.5 watts. Umphathi wesekethe ine owongozelelweyo abafowunelwa-5 (ababini - ukusuka kumthombo uphawu 250, ezimbini - 12.5 I yesihlanu - jikelele - lead) kunye neziphumo ezintathu kwi imveliso eqhagamshelwe kumgca igalelo lwe ikhadi lesandi (ekhohlo kunye nemijelo ekunene kwaye kwabelwane).

Sichubeka njani nenkcazelo kombono zombini. Kwisibini sokuqala kwamagalelo - "umthombo 250" - elidityaniswe resistors R1 R2, ngakumbi - ne R3 ne R4; kwi-terminal output, ngokulandelelana, ekhohlo nemijelo ekunene input line. A pair yesibini "umthombo 12.5 V" "isithuba" elidityaniswe phakathi resistors, ngamanye omnye terminal - R1 R3, kwaye eyesibini - phakathi R2 ne R4. Ke ekugqibeleni, nowokugqibela, imveliso iyonke iya Isidibanisi umgca-in ikhadi lesandi. Okuhlanganiswe imiphantsi ekhohlo nasekunene ngokusebenzisa resistors R5 R6, enxulumene emva iperi resistors R3 ne R4. Ukwenzela ukunciphisa isiphumo ingxolo kwisixhobo, kufuneka ubeke ibhodi adaptha yezindlu metal. Apha, enyanisweni, yonke oscilloscope. Ikhadi lesandi ifumana imiqondiso engenayo, kwaye software ibonisa ukuba amaza kwi esweni kwikhompyutha.

Ukulungisa le program

Ukunyenyisa oscilloscope ukusuka ikhadi lesandi, kufuneka uye ngabenzi PC kwaye ukucima inzuzo kwi umbhobho, awunakucwangcisa umphakamo umqulu ngezantsi avareji. Oku kubangela isixhobo lokulinganisa uyakwazi khetha ngokucacileyo amaza kunokuba njalo, yaye zijongisise amaza uphawu.
