High precision digital multimeters rau cov ntawv thov tshaj plaws
Cov engineers tam sim no tuaj yeem siv NI (National Instruments) multifunctional device - PXI-4071 FlexDMM - kom ua tiav cov haujlwm ntsuas kom raug, nrog cov teeb liab ntawm microamperes mus rau kilovolts. Cov khoom nta muaj xws li 7 ib nrab ntsis (26 khoom) digital multimeter thiab 1.8 MS / s cais digitizer. NI PXI-4071 FlexDMM tso cai rau koj los ntsuas qhov voltages ntawm ± 10 nV thiab ± 1000 V, nrog rau kev tawm tsam ntawm 10 µ W thiab 5 GW. Nws kuj tseem siv cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob, uas tuaj yeem muab 8 DC ntsuas qhov sib txawv ntawm 1 µ A mus rau 3 A, thiab 6 AC ntsuas qhov sib txawv ntawm 100 µ A txog 3 A. Cov yam ntxwv no ua rau cov engineers tau txais kev hloov pauv txaus, versatility, thiab kev muaj peev xwm cais tawm hauv kev siv tswv yim kom ua tiav cov ntawv thov nyuaj xws li kev sim roj hluav taws xob, ntsuas qhov xau, kev ntsuas tus nqi ntxiv, thiab kev ntsuas cov ntaub ntawv hloov pauv.
FlexDMM yog qhov tseeb tshaj plaws digital multimeter rau PXI platform, nrog DC nyeem ntawv tus nqi ntawm 7 S / s ntawm qhov tseeb ntawm 7 1/2 ntsis. Rau cov kev xav tau ntau dua, FlexDMM muab DC nyeem tus nqi txog li 10 kS / s (4 1/2 ntsis raug), uas yog 5 npaug sai dua li cov DMMs uas siv General Purpose Bus Interface (GPIB). Thaum siv hom kev rho tawm digitizer, FlexDMM muaj peev xwm ntawm kev nruam waveform tau los ntawm txhua qhov hluav taws xob thiab tam sim no ntawm qhov ntsuas siab tshaj plaws ntawm 1.8 MS / s. Los ntawm kev ua haujlwm sib cais ua ke, cov kws ua haujlwm tuaj yeem ntsuas qhov sib txawv ntawm qhov sib txawv ntawm 500 volt hom voltage (xws li roj cell pawg kuaj). Los ntawm kev hloov tus nqi piv txwv ntawm tus digitizer, engineers kuj tuaj yeem kho qhov kev daws teeb meem ntawm tus digitizer li ntawm 10 mus rau 23 khoom. Los ntawm kev siv NI LabVIEW graphical programming ib puag ncig, engineers tuaj yeem txheeb xyuas tam sim ntawd, thim rov qab cov cim, thiab ntau lwm yam tsis yog lub caij nyoog siab-voltage DC waveforms ib txhij ntawm cov moos sib txawv thiab zaus thaum siv FlexDMM hauv hom digitizer cais.
