ni 9234 ni 9263 signal error

[leapingfrog]

Hi,

I am running a very basic test on the cRIO:

                                                                    Signal generator  >>  AI (NI 9234)          

                                                                    AO (NI 9263)      >> Oscilloscope

The input is 1khz and i've sent the sample rate of AI to 2.5k which should be enough to produce a smooth signal on the scope. It isn't working like that (i've tried the max of 51.2k s/s and that doesn't work either)

I have dc coupling on, i'm exporting the clock from NI 9234.

I have attached the code please could someone help ?

** Just to note i'm sending a sine wave of +/- 4 volts**

Hey,

I've had a quick look at the VI. Have you tried moving the data rate setting to outside of the while loop? So that you set the data rate once at the start and then not constantly every iteration?

Alternatively, you could set an indicator for the input of the MOD3 node to investigate if the data looks the same before you output it?

Hi Justin,

Thank you very much that was the problem.
