QA402 and Markers

I had a few questions about markers with the QA402…

  1. I am not able to use markers on the Expo Chirp FR sweep after it has been stopped. I know there are times when you can only have one of the traces displayed when using markers with a THD measurement, but I can’t place a marker with either trace selected for Expo Chirp FR.
  2. It would be nice to deselect a marker instead of all of them for the times when you can place a marker.
  3. I believe Matt said that the ability to use delta markers between two traces, as well as between two points on the same trace is coming at some point…?
