Here you can select the sampling parameters. The parameters are different depending on the sampling mode tab selected.
This is also where you can Start sampling.
After sampling starts, the Start button changes to Stop. Before you can start sampling again, Save/Export the session data or take a Screenshot If you don't, you will be prompted about saving any unsaved sampling data before you start sampling again.
Note
If the Power Profiler app closes or crashes before you save the sampling data, you can recover the session later. The Session recovery window appears when you restart the app, listing the sampling sessions that are unsaved. Click Recover to recover sampling results from a listed session.
