Indlela yokwenza i oscilloscope esuka kwikhompyutha yakho?

Oscilloscope yenye izixhobo ezingundoqo, njengaye nawuphi na izicelo kwimizi ilebhu yekhompyutha kwaye umasifundisane radio eqhelekileyo. Ekubeni esi sixhobo, kunokwenzeka ukuba ukujonga ukusilela zobuchwepheshe, yaye kwakhona ukuba isiphene umsebenzi wabo ekuyilweni izixhobo ezitsha. Nangona kunjalo, ixabiso izixhobo ezifana iphezulu kakhulu, hayi zonke engahlawulwayo radio unako ukuthenga into encinane. Eli nqaku lijongana umbuzo ye indlela yokwenza oscilloscope kwi computer yakho. Kukho iindlela ezininzi mveliso isixhobo enjalo, kodwa isiseko yonke indawo, njengokuba ibhodi eza kuyamkela imizwa isandi ikhadi PC, kunye iadaptha okhethekileyo eziqhotyoshelwe kuyo. Inceda kukungqinelanisa amanqanaba umqondiso lulinganiselwa kwaye igalelo audio ikhadi le-computer.

Oscilloscope kwikhompyutha: software

Enye yezona iinkalo ziphambili ifowuni yi-software okuya kwenza ubume monitor kulinganiswa. Kukho iintlobo ezininzi zezinto software ezinjalo, kodwa hayi zonke eziluncedo uzinzile. Ezithandwa kakhulu phakathi radio engahlawulwayo isebenzisa software oscilloscope Osci, ukusuka AudioTester kwikhithi. Kuye interface ikhangeleka ngathi isixhobo umgangatho analog, isikrini igridi evumela ukuba awulinganise ixesha kunye namandla awo yomqondiso. Kuyinto elula ukuyisebenzisa, kwaye eziliqela iimpawu ezongezelelweyo ayifumaneki kwiinkqubo yalo hlobo. Kodwa yonke engahlawulwayo radio uya kukwazi ukukhetha ukubaleka-software, leyo yena uthanda.

idatha yokusebenza

Ngoko ke, ukuze benze oscilloscope ezisuka kwi khomputha yakho, kufuneka uqokelele i attenuator ekhethekileyo (nomabi ombane), apho baya kukwazi ukwenza imisebenzi ngokubanzi uluhlu le ombane elilinganisiweyo. Umsebenzi wesibini zombini - kukukhusela igalelo lezibuko ikhadi lesandi ngumonakalo ezinokubangela kwinqanaba eliphezulu ombane. Uninzi amakhadi sound igalelo ombane kuphela 1-2 volts. Oscilloscope kwi computer yakho uluhlu rhoqo abakhubazeke yesandi ikhadi. Kuba amakhadi iindleko yena ukusuka 0.1Hz ukuya 20kHz (umqondiso sinusoidal). Umda ombane asezantsi, oko kulinganiswa anqongophele ngenxa kwinqanaba imvelaphi nengxolo kwaye 1 MV, kwaye eliphezulu - parameters iadaptha ezithintelweyo kwaye angamakhulu ezininzi volts.

ehlukanisayo izixhobo zombane

Oscilloscope esuka kwikhompyutha iye a busebenze elula kakhulu. Iqulethe ezimbini kuphela diode zener ezintathu resistors. resistors ihlelo kuxhomekeke kwisikali oscilloscope yenyani. Le ehlukanisayo for esikalini ezintathu ezahlukeneyo, kunye ngokulinganayo ka-1: 1, 1:20 no-1: 100. Ngako oko, ifowuni iya kuba amagalelo ezintathu, nganye oludityaniswe a resistor. ukuvimba rated igalelo ngqo resistor 1 Mohm. umqhubi Common uhlobene nge uxhulumaniso reverse ilight ezimbini Zener. Ezi nkundla ke zenzelwe ukuba bakhusele umgca-in overvoltage ikhadi lesandi, xa iswitshi kwi "igalelo ngqo 'indawo. Le resistors bangathungelana enxuseneyo capacitors, baya camabalalisa candelo awo-rhoqo kwefowuni.

isiphelo

Le khompyutha oscilloscope ayikho ecwebezelayo, kodwa olula uyilo wesekethe uya kuvumela uluhlu olubanzi ombane kulinganiswa. Uthe isixhobo kuya kunceda ukulungiswa ezimanyelwayo, okanye ingasetyenziswa njengesixhobo sokulinganisa isifundo.
