已解决! 转到解答。
You would use DAQmx Read with Analog > Multiple Channels > 2D DBL/ 1D Waveform
Physical Channel(s) name i.e Dev0/ai0:3
Please search using the LabVIEW shipped examples with keyword "DAQmx"
"...For continuous single-point input or output, the DAQ Assistant Express VI might not provide optimal performance. Refer to the Cont Acq&Graph Voltage-Single Point Optimization VI in examples\DAQmx\Analog In\Measure Voltage.llb for an example of techniques to create higher-performance, single-point I/O applications."
Above is from the Context Help of DAQ Assistant. FYI
PS: 大多数的Express VI不能提供最佳性能吧! 之所以是Express VI 😉

我用的是LabVIEW8.5的中文版,但是现在做参数辨识时,缺少DAQ Assistant的组件,框图做不出来啊
有谁能做出的,把LabVIEW版原程序框图(参数为电路RC和LC)发到我邮箱里,谢谢啦,是LabVIEW7.1编程与虚拟仪器设计书中373页,包括以后的图。
还有就是谁能帮我找到DAQ Assistant的组件,告诉我一下,都可以发到邮箱里
万分感谢!
如果你用的是试用版LabVIEW,估计是没有数据采集模块的。

你的问题解决了吗?求指点!遇到了相同的问题,DAQ助手同时采集四路,没有办法实现,两路就可以,也是很奇怪呢!
DAQ助手可以同时采集4个通道~
