Possibly you would like to restore or repeat a measurement you performed under spe- cific conditions on the R&S EDST300. 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.
Page 83 Rename.........................84 Factory Preset When delivered, the R&S EDST300 has a default configuration. You can restore this defined initial state at any time as a known starting point for measurements. Presetting is often recommendable as a first step in troubleshooting when unusual measurement results arise.
