Example
:SYSTem:PRESet:SAVe USER1 /*Saves the system status to the user storage location 1 in the internal
memory of the instrument.*/
:SYSTem:PRESet[:STATe]?
Syntax
:SYSTem:PRESet[:STATe]?
Description
Queries user-defined 10 system status names.
Return Format
The query returns 10 system status names. If User n saves the current system status, then the query
returns the current system status name. For example, "Default","","User2","","","","","","","","".

Remarks
 DG800 provides an internal 10 MHz clock source and receives the external clock source from the
rear-panel [10MHz In/Out] connector. It can also output clock source from the [10MHz In/Out]
connector for other devices.
 If "External" is selected, the instrument will detect whether a valid external clock signal is input from
the rear-panel [10MHz In/Out] connector. If no valid clock source is detected, a prompt message is
displayed, and the clock source will be switched to Internal.
 You can synchronize two or multiple instruments by setting the clock source.
 Synchronization between two instruments:
