Indlela yokwenza i oscilloscope kusuka kwikhompyutha yakho?

Oscilloscope ingenye amathuluzi ukhiye, njenganoma iyiphi electronic izicelo ezimbonini laboratory kanye ezivamile workshop umsakazo. Nedivaysi ezinjalo kungenzeka ukunquma ukwehluleka kagesi, futhi ukuze lungisa umsebenzi wabo ekuklanyweni amadivayisi amasha. Nokho, intengo zinsizakuphila kuphezulu kakhulu, futhi akuzona zonke amateur radio abakwaziyo ukuthenga encane. Lesi sihloko iphatha umbuzo indlela yokwenza oscilloscope kusuka kwikhompyutha yakho. Zikhona izindlela eziningi yokukhiqiza leli thuluzi, kodwa isisekelo yonke indawo: njengendlela ibhodi ukuthi uyoyamukela amaza kuyinto ikhadi umsindo PC, futhi adaptha ekhethekile elikulo. Usebenzela avumelana amazinga isignali alinganiswe futhi okokufaka komsindo ikhadi computer.

Oscilloscope kukhompyutha: isofthiwe

Omunye izakhi eziyinhloko zedivayisi yiyona isofthiwe uyonikela ishayela qapha kulinganiswa. Kukhona ezihlukahlukene omkhulu software efana, kodwa hhayi wonke Izinsiza izinze. Ethandwa kakhulu phakathi radio amateur isebenzisa isofthiwe oscilloscope Osci, kusukela AudioTester ungakuphi. It has an interface ukuthi ifana kudivayisi analog ejwayelekile, isikrini grid evumela ukukala ubude kanye amplitude we isignali. Kuyinto elula ukusebenzisa, futhi eziningi izici ezingeziwe ayitholakalanga izinhlelo zalolu hlobo. Kodwa zonke amateur radio uzokwazi ukukhetha ukusebenzisa isofthiwe, okuyinto ayithandayo.

idatha yomsebenzi osizayo

Ngakho, ukuze senze oscilloscope kusuka kwikhompyutha yakho, udinga ukuqoqa attenuator ekhethekile (voltage ehlukanisayo), okuyinto uzokwazi ukumboza ibanzi uhla voltage elinganisiwe. Umsebenzi wesibili ka-adaptha - ukuvikela ikhadi okokufaka port umsindo ekulimaleni ukuthi kungabangela high voltage ezingeni. Iningi amakhadi sound voltage okokufaka kukhawulwe 1-2 volts. Oscilloscope kusuka kwikhompyutha yakho has a ibanga lokuvama abanokukhubazeka ikhadi umsindo. Ngamakhadi izindleko + ngoba ngingummeleli ovela 0.1Hz ukuba 20kHz (isignali sinusoidal). Voltage umkhawulo ephansi, okungase singenakulinganiswa ukhawulelwe ezingeni ingemuva kanye umsindo futhi 1 mV, futhi elingenhla - kuvinjelwe adaptha imingcele futhi kungaba abangamakhulu amaningana volts.

Iinsetjenziswa voltage ehlukanisayo

Oscilloscope kusukela kukhompyutha has a busebenze silula. Iqukethe ezimbili kuphela zener diode futhi ezintathu resistors. Ihlelo resistors incike virtual oscilloscope esikalini. Lokhu ehlukanisayo i izikali ezintathu ezahlukene, ne ratios 1: 1, 1:20 neyoku-1: 100. Ngakho, idivayisi kuyodingeka okokufaka ezintathu, ngamunye okuyinto ixhunywe a Resistor. impedance Kulinganiswe ngo okokufaka ngqo Resistor 1 Mohm. umqhubi Common ixhunyiwe nge uxhumano reverse diodes ezimbili Zener. Ziklanyelwe ukuvikela umugqa-e overvoltage ikhadi umsindo, lapho inkinobho uku "okokufaka ngqo" isikhundla. I resistors kungenziwa exhunywe kuhambisana capacitors, bayoba cabaza ingxenye amplitude-imvamisa zedivayisi.

isiphetho

Le khompyutha oscilloscope akuyona okuchachambile, design kanti ilula wesifunda kuzovumela anhlobonhlobo voltage kulinganiswa. Wathi kudivayisi kuzosiza ukukhanda alalelwayo, noma ingasetshenziswa njengendlela idivayisi wokulinganisa cwaningo.
