I used the example in Labview for basic analog input for FPGA and realtime. For lower frequency sine wave of 10Hz, the signal displayed is fine. However, for higher frequency, 1000Hz, the siganl will not display as it should. When I adjust the timing, it seems that I'm starting to loose chucks of the signal coming in. The reason I'm using the example is becaues the previous VI I made gave the same results with the higher frequencies, so I went back to the basics to see if it might of been with my VI. Is this a timing issue, is it that the module I have can't keep up with the 1000Hz, or will that example not work for what I need? I need to have this run at 1000Hz and get all the data for calculations. Any suggestions?
