DAQmx 与 traditional DAQ 哪个好？

哪个贵哪个好：）

   那，那个东西贵呢？

前者贵，呵呵
DAQmx有很多传统的DAQ没有的特性，你可以上ni.com看看

能实现的，他就是好的，呵呵

建议：能支持mx的肯定用mx。不能支持mx的卡，那就没法，只能traditional..
将来的卡都要淘汰traditional的。所以为了你的程序不再大范围修改，尽量mx吧。NI也不会再对traditional进一步开发了
NI上的说明：
NI-DAQmx is the latest NI-DAQ driver with the following advantages over Traditional NI-DAQ (Legacy):
•    DAQ Assistant—a graphical way to configure virtual channels and measurement tasks for your device, and to generate NI-DAQmx code based on your virtual channels and tasks, for use in LabVIEW, LabWindows/CVI, and Measurement Studio.
•    Increased performance, including faster single-point analog I/O and multithreading.
•    NI-DAQmx simulated devices for testing and modifying applications without plugging in hardware.
•    Simpler, more intuitive APIs for creating DAQ applications using fewer functions and VIs than earlier versions of NI-DAQ.
•    Expanded functionality for LabVIEW, including property nodes and waveform data type support.
•    Similar APIs and functionality for ANSI C, LabWindows/CVI, and Measurement Studio, including native .NET and C++ interfaces.
•    Improved support and performance for the LabVIEW Real-Time Module.
