Yini okubangela i-Oscilloscope?

nguJoost Nusselder | Kubuyekezwe ngomhla ka:  June 20, 2021
Ngiyakuthanda ukudala okuqukethwe kwamahhala okugcwele izeluleko zabafundi bami, wena. Angilwamukeli uxhaso olukhokhelwayo, umbono wami owami, kepha uma uthola izincomo zami zilusizo futhi ugcina uthenga okuthile okuthandayo ngesinye sezixhumanisi zami, bengingathola ikhomishini ngaphandle kwezindleko ezengeziwe kuwe.

Ukuletha imisebenzi yegagasi eyinkimbinkimbi empilweni yilokho okwenziwa yi-oscilloscope ngesikrini sayo sibonisa igrafu kanye ukubala imvamisa yesignali. Kodwa ama-oscilloscopes esimanje enza okuningi kakhulu ngaphandle kokukhombisa i-sine wave yomthombo wamandla kagesi we-AC. Abakhiqizi bahlala bezama ukuyenza ibe ngcono ngokungeza izici eziningi, ezinye zazo okungenzeka zibe zintsha kubasebenzisi abaningi. Amandla okuqalisa ama-waveform esikrinini angenye yalezo zici. Yize izobukeka njengesihloko esilula uma ichazwa kahle, ngandlela thize ikwazile ukudida abasebenzisi abaningi. Ngakho-ke, sizokufundisa konke mayelana nokuqalisa ku i-oscilloscope ngokuphendula imibuzo ejwayeleke kakhulu ehlobene nesihloko.

Yini i-Triggering?

Ngaphambi kokuthi uqonde ukuthi ukucupha kusho ukuthini ku-oscilloscope, kufanele wazi ukuthi igama elithi 'triggering' lichaza ukuthini ngokujwayelekile. Ngamagama alula, ukucupha kusho ukwenza isenzo esithile senzeke. Isibonelo, ungase uqalise ukushintshwa kwefeni ekamelweni lakho okuzokwenza ukuthi ifeni iqale noma iyeke ukuphotha.

Yiziphi Izindlela Zokuqala Ku-Oscilloscope?

Ku-oscilloscope, ukuqalisa kusho ukuyala i-oscilloscope ukuthi ithwebule futhi ibonise i-waveform ezinzile ngaphansi kwesimo esithile ngaphakathi kwamasignali ayinkimbinkimbi. Ngeke uthole i-waveform ecacile futhi ezinzile kuyo yonke isignali yokufaka ku-oscilloscope. I-oscilloscope iklanyelwe futhi yakhelwe ukubonisa wonke amagagasi wesignali yokufaka. Isikhathi esiningi, wonke lawa magagasi ayagqagqana futhi enze kungenzeki kumsebenzisi ukufunda igrafu. Kungakho ukucupha ku-oscilloscope kuvumela abasebenzisi ukuthi babuke ama-waveform ahlangabezana nezimo abazifisayo kuphela.

Kungani Ukuqala Ku-Oscilloscope Kudingeka?

Kuchwepheshe, ukusebenzisa i-oscilloscope kusho ukuqoqa idatha nolwazi kumagagasi aboniswa esikrinini. Kodwa uma isikrini sinamagagasi angafuneki, khona-ke kuyoba nzima ukufunda igrafu. Ngezinye izikhathi, kuyoze kungenzeki. Ngaphandle kwalokho, ukufunda izimo ezikhethekile noma ukucwaninga ngamagagasi kudinga ukuqala.

Ungayivula kanjani i-Oscilloscope?

Kunephaneli ehlukile 'ye-trigger' kuma-oscilloscopes amaningi. Sebenzisa izinkinobho namaknobhu ukuze ulawule ukuma kokucupha, ukuqala noma ukumisa ukushanela, njll. Sebenzisa lezo zinkinobho nokuhlola ukuze ubone ukuthi kwenzekani uma uchofoza noma udayela okuthile. Kufanele ukwazi ukuyifunda ngokushesha okukhulu njengoba isebenziseka kalula.

Izinhlobo Zokucupha ku-Oscilloscope

Kuya nge uhlobo lwesignali yokufaka, amaza akhiqizwa i-oscilloscope angase ahluke ngokwemvelo, futhi adinge izinhlobo ezihlukahlukene zokuvusa. Sizokhuluma ngezinye zezinhlobo ezivame kakhulu zokucupha ezitholakala kukho kokubili ama-oscilloscopes edijithali ne-analog.

I-Edge Triggering Lolu wuhlobo lokucupha oluyisisekelo futhi oluzenzakalelayo kukho kokubili ama-oscilloscopes edijithali ne-analog. Ukucupha umphetho, njengoba negama liphakamisa, kukuvumela ukuthi usethe indawo yokuqala onqenqemeni lwesikrini. Lokhu kuyasiza ikakhulukazi endabeni yamagagasi e-sine. Amagagasi e-sine akhiqizwa emthonjeni we-AC aboniswa njengamazigzag agqagqene esikrinini se-oscilloscope. Lokho kungenxa yokuthi akukho ndawo eqondile yokuqala yalawo magagasi. Ukusebenzisa i-edge triggering, ungasetha leyo ndawo yokuqala. Ngemuva kwalokho, igagasi eliqala ukusuka kulelo phuzu kuphela elizovezwa esikrinini.

Ukucupha iwindi Uma ubufuna ukubuka igrafu yakho uma ingaphakathi kwebanga elithile, kufanele usebenzise i-window trigger. Ithola futhi ikubonise isikhathi lapho i-waveform yayingaphakathi nangaphandle kwebanga elithile lamandla kagesi. Kumuntu ofuna i-over-voltage kanye ne-under-voltage, lena okufanele ayizame.
Iwindi-Ukucupha
I-Pulse Width Triggering Amagagasi e-Pulse afana namagagasi ayisikwele. Ngokuqalisa ububanzi be-pulse, ungakhetha ukubuka amagagasi angaphakathi kwebanga elithile lobubanzi. Uzobeka lobu bubanzi ngokwesidingo sakho. Imiphumela izoba yizimpawu zokushaya kwenhliziyo ezihlangabezana nemibandela yakho kuphela. Lokhu kusiza ukuthola ama-glitches noma amanani adlulele kumasignali akhethekile wokushaya kwenhliziyo.

Isiphetho

Ukucupha ku-oscilloscope ukulungisa nje idivayisi ukuze ubuke amagagasi athile kuphela. Lena inketho ewusizo kakhulu okufanele bonke ochwepheshe baphumelele. Kungase kubonakale kuluqili ekuqaleni kodwa sincoma ukuthi uqale ngezinhlobo eziyisisekelo nezilula zokucupha, ukuze siqale.
