S系列多功能資料擷取卡其Base Clock的穩定度為何?
硬體: Multifunction DAQ (MIO)>>S Series>>PCI-6110
問題: NI 6115,NI 6110以及NI 6111其base clock的穩定度為何?
解答: S系列多功能資料擷取裝置上的base clock其精準度為50 parts per million (ppm)或+/- 0.005%。這個精準度會隨著石英震盪器的使用年齡而改變,但其最大老化速度為+/- 5 ppm per year。在National Instruments的產品目錄中,因為沒有包含精準度老化速度的資訊,所以將其值概略成100 ppm。關於更多clock穩定度的資訊,可以參考下面的連結。
