Problem with Generating Analog Output in 7851R FPGA Card

[Rajesh_Nair]

Hi all

First of all i am a begginer in FPGA programming.

In my application, I am generating some analog voltage, for example 6V in a 7851R FPGA card which is placed in PXI 1033. I am passing this voltage to another PXI having LabVIEW RT. Instead of getting a continous 6V i am getting some spikes having 6V. I am attaching the screenshot of  waveform that obtained in PXI having RT. The PXI card used is PXI 4462. I am also attaching the code. Why i am getting this spikes? Is there any other procedure to generate a continous signal? Is there any problem in acquistion part?

Please help me

Thanks & Regards

Try removing the Loop Timer and compile the FPGA again.
