Sida loo sameeyo oscilloscope ah ka aad computer?

Oscilloscope waa mid ka mid ah alaabta muhiimka ah, sida korontada codsiyada warshadaha shaybaarka iyo workshop radio caadiga ah. Iyada oo qalab noocan oo kale ah waxaa suurto gal ah si loo ogaado failure ee wareeggeedii elektarooniga ah, iyo sidoo kale in ay Debug shaqadooda in design ah ee aaladaha cusub. Si kastaba ha ahaatee, qiimaha qalabka sida waa mid aad u sarreeya, oo aan hiwaayadda kasta radio awoodin in ay iibsadaan wax yar wax caynkaas ah. Maqaalkani waxa uu ka hadlaya su'aasha ah ee sida loo sameeyo oscilloscope ka soo your computer. Waxaa jira habab badan oo soo saarta qalabka noocan oo kale ah, laakiin aasaaska meel kasta waa: sida guddiga in ay aqbalaan doonaa falalkooda waa kaarka codka PC ah, iyo adabtarada gaar ah ku rakiban yihiin. Waxay u adeegtaa si la isu waafajiyo heerka signal qiyaasay iyo kaarka codka talooyin ah ee computer ah.

Oscilloscope on computer ah: software

Mid ka mid ah xubno waaweyn ee qalabka waa software ah in abaalmarin doonaa garaaca wadnaha monitor qiyaasay. Waxaa jira noocyo kala duwan oo badan oo software sida, laakiin dhan biilasha ma tahay mid deggan. Gaar ahaan radio hiwaayadda caansan isticmaalaa software oscilloscope Osci, ka AudioTester xirmada. Waxay leedahay interface ah taas oo u eg qalab analog caadiga ah, shaashadda waa Roobka u ogolaanaya inay ku qiyaasto ee duration iyo Ilodanimada inayan signalka. Waxaa habboon in la isticmaalo, oo uu leeyahay tiro ka mid ah muuqaalada dheeraad ah lagama helin barnaamijyo noocan ah. Laakiin hiwaayadda kasta radio awoodaan in ay doortaan in ay maamulaan software ah, taas oo uu jecel yahay wuxuu noqon doonaa.

xogta farsamo

Sidaas daraaddeed, si uu ugu caddeeyo oscilloscope ka soo your computer, aad u baahan tahay si ay u ururiyaan attenuator gaar ah (qaybiye danab), kaas oo awood u si ay u daboosho sida balaadhan oo kala duwan oo danab ku cabbiro noqon doonaa. function labaad ee adabtarada ah - waa in ay ilaaliyaan kaarka codka dekedda talooyin ka soo dhaawac keeni kara heerka danab sare. Inta badan kaararka dhawaaqa danab talooyin ku eg tahay 1-2 volts. Oscilloscope ka your computer leedahay kala duwan oo inta jeer ee naafada ah kaarka codka. Waayo, kaararka kharashka, isagu waa ka 0.1Hz in 20kHz (signal sinusoidal). Xadka danab hoose, taas oo la qiyaasi laga yaabaa waxaa xadiday heerka asalka iyo sanqadh iyo waa 1 MV, iyo sare - beegyada uu adabtarada xaddidan iyo waxay noqon kartaa dhowr boqol oo volts.

qaybiye danab qalab

Oscilloscope ka computer leeyahay circuitry ah mid aad u fudud. Waxaa ku jira laba kaliya diode zener iyo saddex resistors. resistors heshaan waxay ku xiran tahay miisaanka oscilloscope dalwaddii. Tani qaybiye saddex qolfo leh oo kala duwan, iyadoo saamiga 1: 1, 1:20 iyo 1: 100. Iyadoo la raacayo, qalabka yeelan doontaa saddex gashiga, kuwaasoo mid walba uu ku xiran yahay resistor ah. impedance qiimeeyo resistor talooyin si toos ah 1 Mohm. kaari Common xiran yahay via xiriir dambe ee laba dioska- Zener. Waxay waxaa loogu talagalay si loo ilaaliyo line-in overvoltage kaarka codka, marka biiro waa in ay "la gelin toos ah" meel. resistors waxaa lagu xidhi karaa siman capacitors ah, waxay fidi doonaa qayb Ilodanimada-noqnoqoshada qalab ah.

gunaanad

computer oscilloscope Tani ma aha, design wareeg ah cayishay weli fudud u ogolaan doonaa tiro balaadhan oo ah danab qiyaasay. Ayaa sheegay in qalab kaa caawin doona in dayactirka ah ee audio, ama waxaa loo isticmaali karaa sida qalab qiyaaseed daraasad.
