6014板卡输出问题

[习]

任务是从6014板卡输出1000Hz正弦波电压信号

question1：程序通过调试，但实际上没有电压输出。是程序错误还是硬件问题？程序见附件

question2：Daqmx Create Virtual Channel只能用默认或RSE方式输出，否则返回错误代码。这是为何？

question1:

The question may not be there is no signal out, may be the question is you just did not acquired the signal. I'd prefer to use a standalone oscilloscope to acquire to signal, or use another VI with AI task in it, just don't put the AO and a AI DAQ assistant in a signal loop.

question 2:

As you can see from the Error Message, an analog output task can only work under RSE terminal, if you want to use a differencial output, you can only use to AO channel to group a differencial AO all by yourself
