I haven't often looked at the "Captured" data. Seems like when I do there is nothing there. I've zoomed in/out to full exents, don't see anything. The measurement itself (transfer function) looks fine, just some excessive pre-ringing on one measurement, and I was curious to see the raw data. I note that the checkboxes at bottom of "Captured" screen are greyed out. This was a log sweep measurement, 2 channel using pro upgrade.
