自校准和外部校准的区别是什么? NI Home This Document is not yet Rated Rate this Document 自校准和外部校准的区别是什么? 硬件: Modular Instruments, Multifunction DAQ (MIO) 问题: 自校准和外部校准的区别是什么? 解答: 校准是很重要的,因为任何一个特定的模数转换器的性能都会随着温度、输入电压、时间或其它因素的变化而变化。因此,当校准DMM或者DAQ板卡的时候,就需要考虑上述两种情况。 URL: http://digital.ni.com/public.nsf/allkb/BA55B76C85D4210A8625723900367377

Why do I get Channel Interference and Non-Isolation? I have a voltage source hooked up to a single channel, but the other channels are getting the same reading when they are supposed to be zero. URL: http://digital.ni.com/public.nsf/allkb/D7CDA23B854317E98625720200637C9C
Quelles sont les configurations de gain des cartes séries-S ? J’ai une carte série-S National Instruments. Les configurations de gain sont-elles discrètes ou continues? Si elles sont discrètes, quelles sont les différents gains ? URL: http://digital.ni.com/public.nsf/allkb/DA91EF5997957CD1862571F800501D2B
Dépannage de tensions 'fantômes' liées au crosstalk sur acquisition analogique multi-voie J'emploie une carte d'acquisition de données (DAQ) et je veux acquérir des données sur plusieurs canaux. J'ai un signal alternatif (par exemple, un signal sinusoïdal ou un signal carrée de fréquence de l'ordre de 100 hertz) relié au canal 0 et je laisse les autres entrées déconnec URL: http://digital.ni.com/public.nsf/allkb/9367A49FA72F26BF862571F400442128
