Tag nrho cov cuab yeej ntsuas los ntawm sampLing cov input signals, digitizing qhov tseem ceeb, ua lawv, txuag lawv thiab tso saib lawv.

3.1 Cov tswv yim sib txawv

Cov oscilloscopes feem ntau yog nruab nrog cov qauv, ib qho kawg nkaus inputs, uas yog hais txog hauv av. Qhov no txhais tau hais tias ib sab ntawm cov tswv yim yog ib txwm txuas nrog hauv av thiab lwm sab mus rau qhov kev txaus siab hauv Circuit Court hauv kev sim.

Yog li ntawd voltage uas ntsuas nrog ib qho oscilloscope nrog tus qauv, ib qho kawg inputs yeej ib txwm ntsuas ntawm qhov tshwj xeeb taw tes thiab hauv av.
Thaum voltage tsis yog hais txog hauv av, txuas tus qauv ib qho kawg oscilloscope cov tswv yim rau ob lub ntsiab lus yuav tsim ib qho luv luv ntawm ib qho ntawm cov ntsiab lus thiab hauv av, tej zaum yuav ua rau lub voj voog thiab oscilloscope.

Ib txoj hauv kev nyab xeeb yuav yog ntsuas qhov voltage ntawm ib qho ntawm ob lub ntsiab lus, hauv kev siv hauv av thiab ntawm lwm qhov taw tes, hauv kev siv hauv av thiab tom qab ntawd suav cov voltage qhov txawv ntawm ob lub ntsiab lus. Ntawm cov oscilloscopes feem ntau qhov no tuaj yeem ua tiav los ntawm kev sib txuas ib qho ntawm cov channel mus rau ib qho taw tes thiab lwm cov channel mus rau lwm qhov taw tes thiab tom qab ntawd siv lej ua haujlwm CH1 - CH2 hauv oscilloscope los tso saib qhov tseeb vol.tage sib.

Muaj ib co disadvantages rau txoj kev no:

luv Circuit Court rau hauv av tuaj yeem tsim tau thaum muaj kev sib txuas tsis raug
ntsuas ib lub teeb liab, ob lub channel tau nyob
los ntawm kev siv ob txoj kev, qhov kev ntsuas qhov yuam kev yog nce, qhov ua yuam kev ntawm txhua channel yuav raug muab tso ua ke, ua rau muaj qhov yuam kev loj dua tag nrho.

Hom Kev Tsis Txaus Siab Feem Ntau (CMRR) ntawm txoj kev no yog qhov tsawg. Yog tias ob lub ntsiab lus muaj qhov txheeb ze siab voltage, mas voltage qhov sib txawv ntawm ob lub ntsiab lus yog me me, lub voltage sib txawv tsuas yog ntsuas nyob rau hauv ib tug siab input range, uas ua rau ib tug tsawg daws teeb meem

Ib txoj hauv kev zoo dua yog siv lub oscilloscope nrog cov tswv yim sib txawv.

Ib qho kev tawm tswv yim sib txawv tsis yog hais txog hauv av, tab sis ob sab ntawm cov tswv yim yog "floating". Yog li ntawd nws muaj peev xwm txuas ib sab ntawm cov tswv yim mus rau ib qho taw tes hauv Circuit Court thiab lwm sab ntawm cov tswv yim mus rau lwm qhov taw tes hauv Circuit Court thiab ntsuas qhov vol.tage txawv ncaj qha.

Tus qauv oscilloscope probes thiab attenuators tsuas yog attenuate ib sab ntawm txoj kev teeb liab. Cov no tsis tsim nyog siv nrog cov tswv yim sib txawv. Kev siv cov no ntawm qhov sib txawv ntawm cov tswv yim yuav ua rau muaj kev cuam tshuam tsis zoo rau CMRR thiab yuav qhia txog kev ntsuas qhov yuam kev

Qhov sib txawv Attenuator thiab cov khoom siv ntawm Handyscope HS4 DIFF yog qhov sib txawv, uas txhais tau hais tias sab nraud ntawm BNCs tsis yog hauv av, tab sis nqa lub neej teeb meem.

Thaum siv lub attenuator, cov ntsiab lus hauv qab no yuav tsum tau muab rau hauv kev txiav txim siab:

tsis txhob txuas lwm cov cables rau lub attenuator dua li cov khoom siv nrog lub ntsuas
Tsis txhob kov cov hlau qhov chaw ntawm BNCs thaum lub attenuator txuas nrog lub voj voog nyob rau hauv kev sim, lawv tuaj yeem nqa qhov txaus ntshai vol.tage. Nws tseem yuav cuam tshuam cov kev ntsuas thiab tsim kev ntsuas qhov yuam kev.
Tsis txhob txuas sab nraud ntawm ob lub BNC ntawm lub attenuator rau ib leeg vim qhov no yuav luv luv Circuit Court ib feem ntawm lub voj voog sab hauv thiab yuav tsim kev ntsuas yuam kev.
Tsis txhob txuas sab nraud ntawm BNCs ntawm ob lossis ntau lub attenuators uas txuas nrog ntau txoj hauv kev ntawm Handyscope HS4 DIFF rau ib leeg.
Tsis txhob siv cov khoom siv dag zog ntau dhau rau lub attenuator nyob rau hauv txhua qhov kev taw qhia (xws li rub lub cable, siv lub attenuator li kov los nqa Handyscope HS4 DIFF, thiab lwm yam.)

3.1.2 Cov kev xeem sib txawv

Vim tias qhov sab nraud ntawm BNC tsis txuas nrog hauv av, siv cov txheej txheem shielded coax BNC cables ntawm cov khoom siv sib txawv yuav qhia txog kev ntsuas qhov yuam kev. Cov ntaub thaiv npog ntawm lub cable yuav ua raws li tau txais tus kav hlau txais xov rau lub suab nrov los ntawm ib puag ncig en-vironment, ua kom pom hauv cov teeb liab ntsuas.

Yog li ntawd, Handyscope HS4 DIFF los nrog ib qho kev kuaj tshwj xeeb, ib qho rau txhua qhov channel. Qhov kev sim no yog tsim tshwj xeeb los xyuas kom meej CMRR zoo thiab tiv thaiv lub suab nrov los ntawm ib puag ncig ib puag ncig.

3.3 Sampling nqi

Tus nqi uas tus samples raug muab hu ua sampling tus nqi, tus naj npawb ntawm samples per ob. Siab dua sampling tus nqi sib raug rau lub sijhawm luv luv ntawm samples. Raws li pom hauv daim duab 3.8, nrog qhov siab dua sampling tus nqi, tus thawj teeb liab yuav reconstructed ntau zoo dua los ntawm kev ntsuas samples.

Qhov sampling tus nqi yuav tsum siab tshaj 2 npaug ntawm qhov siab tshaj plaws nyob rau hauv lub teeb liab input. Qhov no yog hu ua Nyquist zaus. Theoretically nws muaj peev xwm recon-struct lub input teeb liab nrog ntau tshaj 2 samples per lub sij hawm. Hauv kev xyaum, 10 mus rau 20 samples ib lub sij hawm raug pom zoo kom tuaj yeem kuaj xyuas lub teeb liab thor-oughly.

3.3.1 Aliasing

Thaum sampling ib tug analog teeb liab nrog ib tug tej yam sampling rate, signals tshwm nyob rau hauv cov zis nrog frequencies sib npaug zos rau cov sum thiab qhov sib txawv ntawm lub teeb liab zaus thiab ntau ntawm cov sampling nqi. Rau example, thaum sampling tus nqi yog 1000 Sa / s thiab lub teeb liab zaus yog 1250 Hz, cov teeb liab zaus hauv qab no yuav muaj nyob rau hauv cov ntaub ntawv tso zis:

Raws li tau hais ua ntej, thaum sampling ib lub teeb liab, tsuas yog frequencies qis dua ib nrab ntawm sampling tus nqi tuaj yeem tsim kho. Hauv qhov no, sampling tus nqi yog 1000 Sa / s, yog li peb tsuas tuaj yeem soj ntsuam cov cim nrog ntau zaus ntawm 0 txog 500 Hz. Qhov no txhais tau hais tias los ntawm qhov tshwm sim ntau zaus hauv lub rooj, peb tsuas tuaj yeem pom 250 Hz teeb liab hauv s.ampcoj cov ntaub ntawv. Lub teeb liab no yog hu ua lub cim ntawm lub cim tseem ceeb.

Yog tias sampling tus nqi qis dua ob zaug ntawm qhov zaus ntawm lub teeb liab input, aliasing yuav tshwm sim. Cov duab hauv qab no qhia tias muaj li cas.

Nyob rau hauv daim duab 3.9, lub teeb liab tawm tswv yim (sab saum toj) yog lub teeb liab daim duab peb sab nrog zaus ntawm 1.25 kHz. Lub teeb liab yog sampcoj nrog tus nqi ntawm 1 kSa / s.
