Hi, I'm having some little trouble with WF. It's complex software so maybe missing something, but may be actual problems, two of them:
1) Wfm math in FFT window is acting little different than expected. I'm doing 0-50MHz sine sweep with ext gen on some filter and would like to see normalized response graph. For that I first create Ref 1 trace using Peak Hold Continuous. Then create filter response trace. Now try to get final plot using Math 1. No desired result since it calculates on current values, not the PHC plots!
2) Persistence window is not taking into account interpolation setting. It should be doing sin(x)/x but instead is doing linear. Also it would be helpful if interpolation setting is not deep in the menu but more easily accessible and perhaps could be individually steered for both Scope and Persistence window. Min/Max is also acting bit weird with low sample counts.
