Using a Restore Point
When you modify the analysis setup and press OK, a restore point is
created. This can be useful when you want to revert to the values you had
prior to changing a test configuration.
You can keep up to three restore points during a working session, but they
are cleared when you start a new session, or if you change the test mode.
