当使用PXI6115高速采集卡采集数据时,采样率为2M,4通道采样。在保存采样200k的数据时出现以下的错误,不知道是什么原因,如何改正?请各位高手指点一下,谢谢!
出现的错误:DAQmx Read (Analog 1D Wfm NChan NSamp).vi:2
Measurements: Attempted to read samples that are no longer available. The requested sample was previously available, but has since been overwritten.
Increasing the buffer size, reading the data more frequently, or specifying a fixed number of samples to read instead of reading all available samples might correct the problem. |
