Digital multimeters nrog siab precision rau kev thov
Cov engineers tam sim no siv tau NI (National Instruments, National Instruments) multi-function device - PXI-4071 FlexDMM kom ua tiav cov haujlwm ntsuas kom raug, cov teeb liab ntau ntawm picoampere mus rau kilovolt, cov khoom nta suav nrog 7½ tus lej (26 khoom) ua haujlwm ntawm digital multimeter thiab 1.8 MS / s digitizer nrog kev sib cais. NI PXI-4071 FlexDMM ua rau koj ntsuas qhov voltages 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 8 DC ntsuas qhov sib txawv ntawm 1 µA txog 3 A thiab 6 AC ntsuas qhov ntsuas ntawm 100 µA mus rau 3 A. Cov peev txheej zoo li no tso cai rau cov engineers kom tau txais kev hloov pauv txaus, ntau yam, thiab kev sib cais kom txaus. Cov ntawv thov nyuaj xws li kev sim roj cell, ntsuas qhov xau, qhov muaj nuj nqis ntxiv nkhaus nrhiav, converter linear data test).
FlexDMM yog qhov tseeb tshaj plaws digital multimeter rau PXI platform, nrog DC nyeem ntawv tus nqi ntawm 7 S / s ntawm 7½-tus lej raug. Rau kev xav tau ntau dua, FlexDMM muab DC nyeem ntawv txog li 10 kS / s (4½-tus lej raug), uas yog tsib npaug sai dua li cov qauv DMMs siv General Purpose Bus Interface (GPIB). Thaum siv hom digitizer nrog kev sib cais, FlexDMM muaj peev xwm ntawm kev nruam waveform nrhiav tau ntawm txhua qhov hluav taws xob thiab qhov tam sim no ntawm qhov ntsuas siab tshaj plaws ntawm 1.8 MS / s. Nrog kev sib cais hauv built-in, engineers tuaj yeem ntsuas qhov sib txawv waveforms nrog ib hom-hom voltage ntawm 500 volts (xws li roj cell stack test). Los ntawm kev sib txawv ntawm tus lej lej tus lej, cov kws ua haujlwm kuj tuaj yeem sib txawv ntawm tus digitizer qhov kev daws teeb meem ntawm 10 txog 23 khoom. Siv FlexDMM nyob rau hauv cais digitizer hom siv NI LabVIEW graphical programming ib puag ncig, engineers muaj peev xwm ib txhij txheeb xyuas cov kev hloov pauv, hloov pauv, thiab lwm yam tsis muaj hluav taws xob DC waveforms ntawm ntau lub moos thiab zaus.
Cov kws tshaj lij tuaj yeem ua kom cov channel suav tau sai ntawm FlexDMM los ntawm kev sib koom ua ke FlexDMM system nrog NI hloov modules xws li NI PXI-2532 512-crossover high-density matrix. Cov kws tshaj lij tuaj yeem ua ke nrog FlexDMM nrog NI hloov modules thiab NI Switch Executive hloov tswj software los ntsuas ntau txhiab channel nrog ib qho multimeter. NI PXI-4071 FlexDMM suav nrog NI-DMM tsav tsheb software rau NI LabVIEW, LabWindows/CVI, thiab Microsoft Visual Studio .NET.
Hais txog NI Modular Instruments:
NI modular instruments muab cov cuab yeej ua haujlwm siab, hloov kho software, thiab lub sijhawm tshiab thiab cov txheej txheem synchronization rau ntau yam kev siv hauv kev sim thiab tsim, suav nrog:
- Kev daws teeb meem siab digitizer (8 txog 12 ntsis, 200 MS / s)
-Signal generator (16 ntsis, 200 MS / s)
- Digital Waveform Generator / Analyzer (100 MHz)
