    Possibly you would like to restore or repeat a measurement you performed under spe- cific conditions on the R&S EVSG1000. Or you would like to troubleshoot a measure- ment and require a defined instrument state to detect the precise cause of the error. In these cases, you can store and recall instrument and measurement settings.
