Oscilloscopes yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob (electronics lab) thiab yog qhov tseem ceeb rau txhua tus neeg tsim hluav taws xob , teeb meem, los yog ua haujlwm nrog high speed electronics. Oscilloscopes yog ib qho ntawm ob peb ntawm cov khoom siv hauv tshuab hluav taws xob uas ua ntau yam haujlwm thiab siv tau los ntawm qhov chaw ntawm lwm yam khoom siv hluav taws xob. Muaj ntau hom tshuaj oscilloscopes rau cov neeg ua haujlwm hobbyist thiab kev ua haujlwm.
Hom Txheej Txheem
Muaj ntau hom oscilloscopes, muaj cov analog thiab digital, thoob plaws ntau ntau yam nqi uas ua rau xaiv qhov oscilloscope txoj kev sib tw . Analog oscilloscopes feem ntau yog siv qhov teeb meem tseem ceeb vim tias cov oscilloscopes coj cov teeb liab, lawv tuaj yeem tsis tau ib cov cim kev hloov uas yuav ua rau cov cwj pwm tsis zoo uas yog vim li cas analog oscilloscopes tseem muaj nuj nqi rau kev txhawj xeeb txog kev hloov, tab sis siab kawg phosphor oscilloscopes muaj peev xwm zoo sib xws.
Analog Oscilloscopes
Ib qho analog oscilloscope ncaj nraim qhia lub teeb liab tos los ntawm ib qho kev sojntsuam thiab qhov tseemceeb hauv nws lub vijtsam. Kev muaj peevxwm ua rau daim ntawv ywj siab ua kom pom tias ntev dua hom tsis zoo lwj. Qhov twg analog oscilloscopes tiag tiag tuaj rau lawv tus kheej yog los ntawm kev ua haujlwm nrog cov teeb liab analog thiab cov teebmeem ntev. Cov hauj lwm suab thiab cov duab analog ua haujlwm zoo heev rau lub peev xwm ntawm ib qho oscilloscope analog oscilloscope uas tseem tuaj yeem lis cov phiaj xwm qeeb zog. Analog oscilloscopes ua kom muaj kev sib txawv zoo dua cov oscilloscopes thiab tsis raug teeb meem ntawm cov teeb meem alias uas ua rau kev nyeem ntawv tsis zoo rau cov oscilloscopes. Analog oscilloscopes feem ntau pheej yig dua cov oscilloscopes thiab feem ntau tseem ceeb rau kev txhim kho zoo thiab muaj kev xaiv zoo rau cov neeg tshiab thiab hobbyists.
Cov Oscilloscopes
Cov oscilloscopes muaj ntau hom. Ob qho tseem ceeb hauv kev ua tau zoo ntawm cov oscilloscopes yog lawv cov qauv sampling thiab bandwidth. Ib qho oscilloscope tus zauv yuav txo nws qhov kev muaj peev xwm mus ntes hlo ntev, ib zaug sijhawm thiab qhov qhwv ntsej ntawm oscilloscope txwv qhov zaus ntawm cov cim taw qhia uas tau tshwm sim los ntawm oscilloscope.
Cov Ntaub Ntawv Cia Hauv Oscilloscopes
Feem ntau cov oscilloscopes yog cov cim oscilloscopes. Cov khoom txuag oscilloscopes tuaj yeem ntes cov xwm txheej thiab xa lawv los tsom xam, kev kos npe, luam ntawv, lossis lwm yam ua. Lawv muaj kev ruaj khov rau cov ntaubntawv povthawj siv thiab lawv tuaj yeem xa tawm mus rau lwm yam xov xwm rau kev cia thiab kev tshuaj xyuas ntawm lub computer. Cov ntaub ntawv cov oscilloscopes tsis tuaj yeem pom cov theem ntawm kev siv ntawm qhov tseeb ntawm lub sijhawm, tsis zoo li cov analog oscilloscope. Cov kev txhaj tshuaj tsuas yog muab tau los ntawm kev siv cov chiv uas tau teem los ntawm kev xuas tes los yog cia li nyob ntawm tus oscilloscope. Cov ntaub ntawv khaws cia oscilloscopes yog cov kev sib tw ntawm lub ntiaj teb cov qauv digital uas muaj plaub qho los yog ntau tshaj tawm kev tshawb fawb ib txhij.
Cov Phosphor Oscilloscopes
Rau kev ceev dua cov teeb liab cov cim thiab kev ntsuam xyuas, Cov phosphor oscilloscopes trump tus qauv ntawm cov ntaub oscilloscopes. Cov phosphor oscilloscopes siv lub txheejtxheem ADC uas ua haujlwm kom xa cov nqi qis tshaj ntawm cov tshuaj txuag oscilloscopes. Qhov sampling feem no ua rau lub teeb liab pom tau theem uas muaj qhov pom ntawm qhov tseeb.
Cov phosphor oscilloscopes tau txais lawv lub npe los ntawm lawv cov kev zoo sib thooj rau analog oscilloscopes hauv kev teeb tsa qhov kev siv ntawm ib lub teeb liab. Hauv qhov analog oscilloscopes no yog vim phosphorus ntawm lub CRT monitor glowing rau lub sijhawm ua ntej yuav tsaus ntuj uas tso cai rau kev kub ceev kom muaj zog ci ntsa iab nyob rau thaj tsam lawv tshaj plaws thiab rau cov me nyuam tseem tuaj yeem sawv tawm. Cov phosphor oscilloscopes duplicate cov nyhuv ntawm phosphorus los ntawm kev khaws cov ntaub ntawv ntawm qhov tseem ceeb ntawm cov kab rov ua dua rov qab thiab nce qhov kev siv ntawm cov khoom nyob qhov twg cov ntaub ntawv khoob khoob. Zoo li cov analog oscilloscope, muaj cov phosphor uas qhia tau rau cov neeg tau pom los ntawm kev siv theem siab, tab sis nws tseem tuaj yeem ua rau cov neeg tsis sib haum xeeb uas tshwm sim sab nraud ntawm cov ntaub ntawv tuav lub qhov rais thiab nws cov nqi hloov tshiab.
Cov phosphor oscilloscopes muab cov nta ntawm cov ntaub oscilloscopes thiab analog oscilloscope technology, ua rau lawv zoo rau kev tsim qauv, cov sij hawm digital, kev tshuaj ntsuam xyuas, kev sib txuas lus sib txuas lus thiab kev daws teeb meem.
Mixed Domain Oscilloscopes
Kev sib koom tes ntawm tus qauv soj ntsuam ntawm RF, logic analyzer, thiab cov oscilloscope thiab koj tau txais ib qho kev sau qoob loo oscilloscope. Thaum tsim los ua haujlwm nrog cov teeb meem digital, digital logic, thiab kev sib txuas lus xov tooj cua sib txuas, sib xyaw sau cov oscilloscopes ua ib qho cuab yeej tseem ceeb. Qhov tseem ceeb ntawm kev sib xyaw cov oscilloscope yog pom cov teeb meem ntawm txhua tus sau, analog, RF, thiab logic, lub sij hawm sib raug zoo rau ib leeg. Qhov no ua rau kev daws teeb meem, kev sib tw, kev sib tw, thiab tsim kev xeem uas tso cai rau txhua lub teeb liab kom sib haum thaum lub sijhawm.
Mixed Signal Oscilloscopes
Feem ntau qhov ua tau ntawm cov oscilloscope thiab logic analyzer yuav tsum tau ua ke, uas yog vim li cas qhov sib xyaw nrog oscilloscope tau tsim. Lub teeb xyaw oscillocope muab cov ntaub oscilloscope khaws cia (los yog cov phomphor oscilloscope) nrog cov kev ntsuas ntau lub voj tshuab. Cov cuab yeej ua kom muaj zog ntawm cov teeb meem ntawm cov oscilloscope (AI) uas yog cov kev ntsuam xyuas ntawm analog cov xwm txheej uas ua rau cov logic hloov. Feem ntau cov teeb xyaw oscilloscopes tsuas muaj ob los yog plaub analog tawm channels thiab ib ncig ntawm 16 cov kev tawm tswv yim.
Cov Kev Xeem Oscilloscopes
Cov zauv oscilloscopes muaj cov txheej txheem me ntsis txawv lwm qhov oscilloscopes thiab cov lag luam tawm ntau ntau dua bandwidth rau sab qis dua. Cov tswv yim tsis muaj zog lossis ua kom nrov loj dua li oscilloscope yuav tsum muaj peev xwm tswj tau tag nrho cov kev tawm tswv yim, uas feem ntau tsuas yog siv li ntawm 1 volt ncov-mus-ncov. Cov zauv oscilloscopes tsuas yog ua haujlwm ntawm cov cim kev rov qab ua dua thiab yuav tsis pab txhom tau cov neeg thau dhau qhov lawv cov qauv qiv dua. Ntawm qhov tod tes, cov zauv oscilloscopes tuaj yeem ntes cov teebmeem uas yog qhov kev txiav txim siab ntawm qhov ntau tshaj li lwm hom oscilloscopes, nrog bandwidths tshaj 80 GHz.
Handheld Oscilloscopes
Cov iav oscilloscopes me me muaj rau daim teb thiab daim ntawv teev npe seb qhov twg yog qhov oscilloscopes uas tsis muaj zog lossis lub zog tsis yooj yim. Lawv feem ntau yog tsawg rau ob qho kev siv nyiaj thiab muaj cov bandwidth thiab qauv tus nqi.
Computer Based Oscilloscopes
Ib qho ntawm cov kab mob oscilloscopes yog lub computer raws li oscilloscope, feem ntau yog ib qho cuab yeej txuas nrog lub computer los ntawm USB. Cov hom oscilloscopes tau tsim cov kab xo loj hauv kev ua haujlwm, ua rau lawv cov nqi qiv dua, kev siv bandwidth thiab tag nrho cov peev xwm. Qee cov txheej txheem ua kom muaj peev xwm ntawm cov khoom qis kawg ntawm cov oscilloscopes rau ob peb txhiab daus las thiab ua rau cov neeg ua haujlwm hobbyists nrhiav kev oscilloscope.
