Choosing the correct DMA FIFO datatype is essential as incorrect datatypes may lead to truncation or approximation of data, thus distorting the signal. As mentioned in the document Creating FIFOs in FPGA VIs (FPGA Module), Right click on the FPGA target in your project explorer window, select New>>FIFO to display the FIFO properties. For existing FIFOs, Double-Click the FIFO under the project explorer window to open the Dialog box. Now specify the appropriate datatype as to avoid any truncation or saturation.
Make sure you select the correct plot and interpolation settings of your Chart/Graph in the host VI. Refer to the help document of Graph/Chart for detailed information on them.
You need to make sure there are no buffer errors leading to loss of data. There are some caveats to be followed to avoid buffers error and to detect them. Refer to help document Avoiding Buffer Errors in DMA Applications (FPGA Module) for more information.
