Mwinamwake mwawona amatsenga ambiri kapena amatsenga ali ndi ndodo zawo m'mafilimu, chabwino? Wand izi zidawapangitsa kukhala amphamvu kwambiri ndipo amatha kuchita chilichonse. Ha, ngati izi zinali zoona. Koma mukudziwa, pafupifupi wofufuza aliyense ndi labu amabwera ndi matsenga wand nayenso. Inde, izi ndi oscilloscope zomwe zinatsegula njira yopangira matsenga. 
Mu 1893, asayansi anapanga gizmo yaikulu, oscilloscope. Udindo waukulu wa makinawo unali wakuti ukhoza kutenga kuwerenga kwa zizindikiro zamagetsi. Makinawa amathanso kukonza mawonekedwe a siginecha mu graph. Maluso awa adasokoneza chitukuko cha magawo amagetsi ndi mauthenga.
Panthawi imeneyi, ma oscilloscopes ali ndi zowonetsera ndipo amawonetsa kugunda kapena chizindikiro mwamphamvu kwambiri. Koma chifukwa chaukadaulo wa oscilloscopes adagawidwa m'mitundu iwiri. Digital oscilloscope ndi analogi oscilloscope. Kufotokozera kwathu kukupatsani lingaliro lomveka bwino lomwe mukufuna.
Mu positi iyi tikambirana:
Kodi Analogi oscilloscope ndi chiyani?
Ma oscilloscopes a analogi ndi mitundu yakale ya digito oscilloscopes. Zidazi zimabwera ndi mawonekedwe ocheperako komanso kuwongolera. Mwachitsanzo, ma oscilloscopes awa amabwera ndi machubu akale a cathode ray, bandwidth yocheperako, ndi zina zambiri.
History
Pamene katswiri wa sayansi ya ku France André Blondel anapanga makina otchedwa oscilloscope, ankakonda kupanga maginito a magetsi pa graph. Popeza inali ndi zoletsa zambiri, mu 1897 Karl Ferdinand Braun anawonjezera chubu cha cathode ray kuti awone chizindikiro chowonetsera. Pambuyo pa chitukuko chochepa, tinapeza oscilloscope yathu yoyamba ya analogi mu 1940.
Features ndi Technology
Ma oscilloscopes a analogi ndi osavuta kwambiri pakati pa omwe akupezeka pamsika. M'mbuyomu, ma oscilloscopes awa adachitika kuti apereke CRT kapena cathode ray chubu kuti awonetse chizindikiro koma pakali pano, mutha kupeza LCD yowonetsedwa mosavuta. Nthawi zambiri, izi zimakhala ndi njira zochepa komanso bandwidth, koma izi ndizokwanira pamisonkhano yosavuta.
Kugwiritsa Ntchito Masiku Ano
Ngakhale oscilloscope ya analogi ingamveke ngati yakale, izi ndi zokwanira kwa inu ngati ntchito zanu zili mu mphamvu ya oscilloscope. Ma oscilloscopes awa sangakhale ndi zosankha zambiri ngati digito koma kwa oyamba kumene, izi ndizokwanira. Chifukwa chake, muyenera kudziwa zomwe mukufuna poyamba mosasamala za mtundu wake.
Kodi Digital Oscilloscope ndi chiyani?
Pambuyo pakuchita khama komanso pulogalamu yachitukuko, digito oscilloscope idabwera. Ngakhale mfundo zazikuluzikulu za ntchito zonse ziwirizi ndi zofanana, digito imabwera ndi luso lowonjezera lakusintha. Itha kupulumutsa mafunde ndi manambala ena a digito ndikuyiwonetsa pachiwonetsero ndikuyilemba.
History
Kuyambira pa oscilloscope yoyamba, asayansi anapitirizabe kufufuza kuti apange izo mowonjezereka. Pambuyo pazitukuko zingapo, oscilloscope yoyamba ya digito idabwera pamsika mchaka cha 1985. Ma oscilloscopes awa anali ndi bandiwifi yotakata modabwitsa, kugwiritsa ntchito mphamvu zochepa, ndi zina zazikulu zowonjezera.
Features ndi Technology
Ngakhale izi ndizinthu zapamwamba kwambiri pamsika, palinso zosiyana pakati pa ma oscilloscope a digito malinga ndiukadaulo wawo. Izi ndi:
- Digital Storage Oscilloscopes (DSO)
- Digital Stroboscopic Oscilloscopes (DSaO)
- Digital Phosphor Oscilloscopes (DPO)
DSO
Ma Digital Storage Oscilloscopes adangopangidwa komanso kugwiritsa ntchito ma oscilloscope a digito. Makamaka, zowonetsera zamtundu wa raster zimagwiritsidwa ntchito mu ma oscilloscopes awa. The drawback yekha wa izi mtundu wa oscilloscopes ndikuti ma oscilloscopes awa sangathe kudziwa kuchuluka kwa nthawi yeniyeni.
DSaO
Kuphatikizidwa kwa mlatho wachitsanzo pamaso pa attenuator kapena amplifier circuit kumapangitsa kuti ikhale yosiyana kwambiri. Mlatho wachitsanzo umapereka chizindikiro chisanachitike njira yokulitsa. Monga chizindikiro cha sampuli chimakhala chafupipafupi, chowonjezera chochepa cha bandwidth chimagwiritsidwa ntchito chomwe chimapangitsa kuti mafunde amveke bwino komanso olondola.
DPO
Digital Phosphor Oscilloscope ndiye mtundu wakale kwambiri wa digito oscilloscope. Ma oscilloscopes awa sagwiritsidwa ntchito kwambiri masiku ano koma ma oscilloscopes awa ndi amitundu yosiyana kotheratu. Chifukwa chake, ma oscilloscopes awa amatha kupereka kuthekera kosiyanasiyana ndikumanganso chizindikiro pachiwonetsero.
Kugwiritsa Ntchito Masiku Ano
Digital oscilloscopes ndiye oscilloscope apamwamba kwambiri omwe akupezeka pamsika. Choncho, palibe kukayikira za kugwiritsidwa ntchito kwawo masiku ano. Koma chinthu chimodzi muyenera kukumbukira kuti, muyenera kusankha yoyenera kwambiri. Chifukwa luso la oscilloscopes limasiyanasiyana malinga ndi zolinga zawo.
Analogi Oscilloscope Vs Digital Oscilloscope
Mosakayikira, digito oscilloscope imafika pamwamba pa analogi, kufananiza zosiyana. Koma kusiyana kumeneku kungakhale kopanda ntchito kwa inu chifukwa cha ntchito yanu. Kuti tithetse vutoli, tikupereka fanizo lalifupi kuti muvomereze kusiyana kwakukulu.
Ma oscilloscope ambiri a digito amaphatikizapo zowonetsera zakuthwa komanso zamphamvu za LCD kapena zowonetsera za LED. Pomwe, ma oscilloscopes ambiri a analogi amabwera ndi zowonetsera za CRT. Digital oscilloscopes amabwera ndi kukumbukira komwe kumasunga nambala ya digito ya chizindikirocho komanso kutha kuyikonza.
Kukhazikitsidwa kwa ADC kapena analogi to digital converter circuit kumapangitsa kusiyana kwakukulu pakati pa analogi ndi digito oscilloscope. Kupatula pazidazi, mutha kukhala ndi njira zambiri zamasinthidwe osiyanasiyana ndi zina zowonjezera zomwe sizipezeka mu analogi oscilloscope.
Malangizo Omaliza
Kwenikweni, mfundo zogwirira ntchito za analogi ndi digito oscilloscopes ndizofanana. Digital oscilloscope imaphatikizapo matekinoloje ena owonjezera opangira ma siginecha bwino ndikuwongolera ndi njira zambiri. M'malo mwake, oscilloscope ya analogi ingaphatikizepo zowonera zakale ndi mawonekedwe. Mutha kuganiza kuti ali ngati multimeter yokhala ndi graph, koma pali zina zofunika kusiyana pakati pa oscilloscope ndi graphing multimeter.
Ngati mulibe kusiyana pakati pa analogi ndi digito oscilloscope, ndiye kuti muyenera kupita ku digito oscilloscope. Chifukwa digito oscilloscope imabweretsa ndalama zambiri kuposa analogi. Kwa ntchito zosavuta zapakhomo kapena zasayansi, ma analogi kapena oscilloscope a digito sizipanga kusiyana kulikonse.
