I have a LabVIEW application which plots FFTs on two analog channels of the PXIe 7856R card. When I apply a complex signal on the R&S signal generator with modulation, the whole graph flickers. I don't know so much about labview, can someone help me if this is a sampling error or if I should do an averaging, maybe someone can help me fix the problem?How can I put in a graph showing the phase change ?
