Digital multimeters rau kev thov kev siv nrog cov neeg siab
Cov engineers tam sim no tuaj yeem ntsuas qhov tseeb nrog PXI-4071 FlexDMM, ntau yam khoom siv los ntawm NI (National Instruments) nrog lub teeb liab ntawm microamps rau kilovolts, muaj 7½-ntsis (26-ntsis) digital multimeter thiab 1 8 MS/s digitiser nrog kev cais. Cov khoom siv digital multimeter thiab 1.8 MS / s digitiser nrog kev sib cais.The NI PXI-4071 FlexDMM ua rau koj ntsuas qhov ntsuas qhov tseeb ntawm ± 10 nV rau ± 1000 V thiab tiv taus ntawm 10 µW txog 5 GW. Nws kuj tseem siv cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob los muab yim qhov ntsuas DC ntawm 1 µA mus rau 3 A, thiab rau qhov ntsuas AC ntawm 100 µA txog 3 A. Qhov kev muaj peev xwm no ua rau cov engineers ntsuas qhov voltages ntawm ± 10 nV rau ± 1000 V. thiab kuj los ntawm 10 µW mus rau 5 GW. Qhov no muab cov engineers qhov yooj yim, ntau yam, thiab kev sib cais kom txaus nyob rau hauv cov ntawv thov nyuaj xws li kev sim roj hluav taws xob, ntsuas cov dej xau, kev ntsuas tus nqi ntxiv, thiab kev ntsuas cov ntaub ntawv hloov pauv linearity.
FlexDMM yog qhov tseeb tshaj plaws digital multimeter rau PXI platform, nrog DC nyeem tus nqi ntawm 7 S / s ntawm 7½-ntsis raug, thiab rau cov kev xav tau ntau dua, FlexDMM muab DC nyeem tus nqi txog li 10 kS / s ntawm 4½-ntsis raug, uas yog mus txog 5 npaug sai dua li cov qauv DMMs siv General Purpose Bus Interface (GPIB). Thaum siv hauv hom digitiser nrog kev sib cais, FlexDMM muaj peev xwm ntawm kev nruam waveform tau los ntawm txhua qhov hluav taws xob thiab qhov tam sim no ntawm tus qauv siab tshaj plaws ntawm 1.8 MS / s. Nrog kev sib cais hauv built-in, engineers tuaj yeem ntsuas qhov sib txawv waveforms nrog 500 volts ntawm hom voltage (piv txwv li, roj cell stack test). Los ntawm kev sib txawv ntawm tus lej digitiser tus qauv, cov kws ua haujlwm kuj tuaj yeem hloov qhov kev daws teeb meem ntawm digitiser ntau ntawm 10 txog 23 khoom. Siv lub NI LabVIEW graphical programming ib puag ncig, engineers tuaj yeem tshawb xyuas ib ntus, hloov pauv cov teeb liab, thiab ntau yam ntawm lwm yam uas tsis yog lub caij nyoog, siab-voltage DC waveforms ntawm ntau lub moos thiab zaus thaum siv FlexDMM hauv hom digitizer nrog kev cais.
Cov kws tshaj lij tuaj yeem ua kom cov xov tooj hauv FlexDMM nrawm nrawm los ntawm kev sib koom ua ke FlexDMM system nrog NI's switching modules, xws li NI PXI-2532 512-Cross High-Density Matrix. Cov engineers tuaj yeem sib txuas FlexDMM nrog NI hloov modules thiab NI Switch Executive hloov tswj software los ntsuas ntau txhiab channels nrog ib qho multimeter.The NI PXI-4071 FlexDMM suav nrog NI LabVIEW, LabWindows/CVI, thiab Microsoft Visual Studio . Studio .NET NI-DMM tsav tsheb software.
