simulate arbitrary signal VI

[flystar1982]

Hi,I want to use simulate arbitrary signal VI to load the data and then output it to control the shaker motion, one problem is that when the VI outputs the data point-by-point, its time interval is not the real time step in the data, so how can I change the time interval, if this can not be achieved with simulate arbitrary signal VI, what VI should I use?

thanks a lot,

 Hey flystar,

Perhaps you could attach your code so I can understand what you're trying to do, and to see what you've managed to do so far. 

Kind regards,

Hi all,

I hope you are all fine. I am trying to generate the simulated brain sign. I got all the data set for the time and the value of y-axis but when i used cDAQ NI 9178 to interface my signal and see it on oscillscope, there is error. in the software it works ok but hardware can not .i dont know what is wrong,

kindly can you help me in this issue.

error is

Error -200292 occurred at DAQmx Write (Analog 1D Wfm NChan NSamp).vi:3

Task Name: _unnamedTask<14>

A compact DAQ 9178 is just a chassis.  Which cDAQ modules are you using in it?

100,001 samples may just be too many for the size of the buffer.  Did you try any of the hints in the error message for -200292 such as increasing the Write timeout?  You have a dx of 300 microseconds, but 100,001 samples.  So that would take 30 seconds to run.  That is longer than the typical write timeout of 10 seconds.

(By the way, you probably should have started a new thread with your question rather than adding on to an old thread with an unrelated question.)
