Indlela yokulinganisa i-oscilloscope: umhlahlandlela wesinyathelo ngesinyathelo

I-oscilloscope iyithuluzi le-elekthronikhi elibalulekile elisetshenziswa emikhakheni ehlukene ngezinjongo ezahlukene.

Nakuba inhloso ye-oscilloscope ikhawulelwe ekulinganiseni amasiginali kagesi nokufunda ukuthi amasiginali ashintsha kanjani ngokuhamba kwesikhathi, ithuluzi libuye libe usizo lapho kuxazululwa amasekhethi kagesi. 

Nokho, umphumela owuthola nge-oscilloscope uncike ekutheni ilinganiswe kahle kangakanani. I-oscilloscope elinganiswe kahle inikeza imiphumela enembayo ongathembela kuyo, kuyilapho ithuluzi elingalinganiswa kahle lizohlanekezela imiphumela yakho.

Ngakho-ke, ufuna ukulinganisa i-oscilloscope. Nokho, inkinga eyinhloko indlela ukulinganisa oscilloscope. 

Lesi sihloko sinikeza umhlahlandlela wesinyathelo ngesinyathelo sokulinganisa i-oscilloscope.

Kuyini ukulinganisa?

Ukulinganisa kuvame ukuqhathanisa amadivaysi amabili okulinganisa. Ekulinganisweni, idivayisi eyodwa ihlinzeka ngezinga lokulinganisa, kanti enye idivayisi kufanele ihambisane nezinga elinikeziwe. 

Ukulinganisa kuhlola umehluko emiphumeleni yokulinganisa yemishini emibili yokulinganisa futhi kuqinisekisa ukuthi okungalungile okuncane kwamadivayisi womabili kuhlangabezana nezinga lereferensi elinikezwa yileyo efanele. Le nqubo ihloselwe ukuthuthukisa ukunemba kwezinsimbi, okunikeza imiphumela enembile ngesikhathi sokuhlolwa.

Ukulinganisa okujwayelekile kwezentengiso kwenziwa kusetshenziswa izilinganiso zereferensi nezinqubo zomkhiqizi. Izinga ngokuvamile linembe ngokuphindwe kane kunethuluzi elilinganisiwe.

Ngakho-ke, ukusetshenziswa kwethuluzi elisha kunikeza imiphumela efanayo namanye amathuluzi anembayo, inqobo nje uma esetshenziswa ngaphansi kwezimo ezifanayo.

Kuma-oscilloscopes, ukulinganisa kwe-oscilloscope kuyinqubo yokulungisa i-oscilloscope ukuze kutholwe imiphumela phakathi kwebanga elamukelekayo. 

Indlela yokulinganisa i-oscilloscope

Nakuba ama-oscilloscope eza ngezinhlobo namamodeli amaningi ahlukene, futhi inqubo yokulinganisa engcono kakhulu yama-oscilloscopes ahlukene iyahlukahluka, lo mhlahlandlela ojwayelekile uzokutshela ukuthi ungayiqedela kanjani inqubo.

Ngokufunda imanuwali yemiyalo ye-oscilloscope yakho, uzofunda kabanzi mayelana nokulinganisa ithuluzi lakho elithile.

Nazi izinyathelo ezijwayelekile zokulinganisa i-oscilloscope:

1. Setha zonke izilawuli zibe ezejwayelekile

Hlola zonke izilawuli futhi uzibeke endaweni evamile. Nakuba lesi silungiselelo sihluka ngohlobo lwe-oscilloscope, ama-oscilloscope amaningi adinga ukuthi ubeke maphakathi zonke izidayeli eziphendukayo futhi welule zonke izinkinobho. 

2. Vula i-oscilloscope

Uma une-CRT yesidala, inike imizuzu embalwa yokufudumala.

3. Setha isilawuli se-VOLTS/DIV kuzilungiselelo ozifunayo.

Noma ungakhetha inani olifisayo lepharamitha ye-VOLTS/DIV, ngokuvamile kuhle kakhulu ukulisethela ku-1 ngezinjongo zokulinganisa. Ukuyimisa ibe ngu-1 kuvumela i-oscilloscope ukuthi ibonise i-volt eyodwa esigabeni ngasinye siqonde phezulu. 

4. Setha TIME/DIV kunani eliphansi kakhulu

Lesi silungiselelo, ngokuvamile esingu-1 ms, sinikeza i-oscilloscope ukuhlukana okuvundlile ukumela isikhawu sesikhathi. Landela lokhu ngokuphendula inothi yokudayela eyodwa ngesikhathi, kancane kancane uguqule ichashazi libe umugqa oqinile.

5. Vula iswishi yokucupha uye endaweni ethi "Okuzenzakalelayo".

Lokhu kwenza kube lula ukubona i-waveform esikrinini. I-Auto Trigger isiza ukusungula iphuzu elivamile le-trigger ku-waveform ukuze kuzinziswe umkhondo. Ngaphandle kwalokhu, isignali iyakhukhuleka futhi kunzima ukuyibona. 

6. Xhuma i-oscilloscope kusiginali yokufaka

Lapho ulinganisa i-oscilloscope, kubalulekile ukuyixhuma kusignali yokufaka. Qala ngokuxhuma i-probe ensimbini. Uma unamajekhi okokufaka amaningi, xhuma inzwa kujeke obhalwe A. 

I-Oscilloscopes ivamise ukuba ne-input probe kanye nentambo yaphansi/i-clamp. I-probe yokufaka ivamise ukuxhunywa kusignali yokokufaka, futhi intambo yaphansi ixhunywe kunoma iyiphi indawo yaphansi kusekethe. 

7. Xhuma i-probe kusixhumi sokulinganisa se-oscilloscope.

Lokhu kuzohlinzeka ngesampula yegagasi lesikwele esidingekayo ukuze kulinganiswe insimbi yakho. Amanye ama-oscilloscope anamatheminali amabili, ngokuvamile angu-0.2V kanye no-2V. Uma ithuluzi lakho linamatheminali amabili, sebenzisa i-2V ngale njongo. 

Ukubeka i-probe kutheminali yokulinganisa kungaba nzima, ikakhulukazi uma inomkhawulo oqondile. Yize isiqeshana sokuhlola isiqeshana sengwenya kulula ukusibeka kutheminali yokulinganisa, ungase ungaqondi ukuthi usetshenziswa kanjani uphenyo olucijile.

Beka i-probe ecijile kutheminali ngokuphusha ithiphu embotsheni encane ekugcineni kwetheminali yokulinganisa.

Ufuna ukubuza ukuthi kudingekile yini ukuxhuma ucingo oluphansi. Uma usebenzisa i-oscilloscope kumjikelezo kagesi, kubalulekile ukuxhuma inhlabathi ye-oscilloscope emthonjeni oxhunywe emhlabathini. Lokhu kwenzelwa ukuvimbela ubungozi bokushaqeka kukagesi kanye nokulimala kwesekethe.

Nokho, uxhumano lwentambo yaphansi aludingeki ngezinjongo zokulinganisa. 

8. Setha igagasi

Uma igagasi eliyisikwele elibonisiwe lingalingani esikrinini, ungahlala ulilungisa usebenzisa izilawuli ze-TIME/DIV kanye ne-VOLTS/DIV. 

Ezinye izilawuli eziwusizo zifaka izilawuli ze-Y-POS ne-X-POS. Ngenkathi isilawuli se-Y-POS sisiza phakathi nendawo ijika ngokuvundlile, i-X-POS imisa ijika liqonde phezulu.

Manje ungasebenzisa i-oscilloscope ukukala amasignali kagesi futhi uthole imiphumela enembile. 

Kungani kufanele ngilinganise i-oscilloscope yami?

Yebo, kufanele ulinganise i-oscilloscope. Njengamanye amathuluzi kagesi, ukulinganisa i-oscilloscope kusiza ukuqinisekisa ukuthi ifinyelela izindinganiso ezamukelekayo nokuthi imiphumela eyikhiqizayo eyabanye onjiniyela nososayensi. 

Ngakho-ke, qiniseka ukuthi i-oscilloscope yakho ilinganiselwe ngokuyihlola njalo. Lokhu kuzokwenza imiphumela yakho yokuhlola ithembeke futhi kukunike ukuzethemba lapho uthatha izilinganiso ngethuluzi. Ikakhulukazi uma usebenzisa i-oscilloscope ngomsindo, zonke izilungiselelo kufanele zilungile.

I-oscilloscope kufanele ilinganiswe kangaki?

Imvamisa ye-oscilloscope calibration incike ohlotsheni lwe-oscilloscope onalo. Kodwa-ke, isikhawu esimaphakathi esinconyiwe sokulinganisa izinyanga eziyi-12.

Nakuba lokhu kungase kuhluke kuye ngohlobo nemodeli ye-oscilloscope, indawo yokuhlola nayo idlala indima ebalulekile ekutheni i-oscilloscope ilinganiswa kaningi kangakanani. 

Ngakho-ke, ufuna ukuhlola indawo yakho yokuhlola ukuze ubone ukuthi ithinta kangakanani ukunemba kwe-oscilloscope yakho.

Izinto eziningi zinesibopho semiphumela engalungile nge-oscilloscope. Isibonelo, izici ezinjengomswakama owedlulele, ukudlidliza, ukushintsha kwezinga lokushisa, nothuli kungathinta ukunemba kwe-oscilloscope, kufinyeze isikhawu sokulinganisa. Futhi

Uma sekushiwo, ufuna ukulandelela imiphumela yakho futhi uhlole ukuthi inembile yini. Imiphumela yakho yokuhlolwa ephambuka emiphumeleni evamile iyinkomba eyanele yokuthi insimbi yakho idinga ukulinganiswa, kungakhathaliseki ukuthi ugcine nini ukuyilinganisa.
