timing question in a simulate signal (DaqAssistant output)

[Johnnykoo]

Hi, I was working on a simulating waveform to the output DAQ asssistant box (trying to generate sinewave form from amplifier)

and.. for some reason, I can't run my program

I thought, if i  set the DAQ assistant to be "On Demand" it would take whatever it receives, : (

the error message said, there are some problems with sample rate, 

I'm attaching couple of pictures, please help me : (

No. On Demand is not that at all. On Demand means to take a single value (a scalar) and write that. It does not accept a waveform. You would want to use N Samples or Continuous
