RIGOL Chapter 2 Command System
2-154 DG2000 Programming Guide
Remarks
 DG2000 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:
Connect the [10MHz In/Out] connector of Generator A ("Internal" clock) to the [10MHz In/Out]
connector of Generator B ("External" clock) and set the output frequencies of A and B to a same value
to realize synchronization between two instruments.
 Synchronization among multiple instruments:
Divide the 10MHz clock source of a Generator ("Internal" clock) into multiple channels, and then
connect them to the [10MHz In/Out] connectors of other generators ("External" clock) respectively,
and finally set the output frequencies of all the generators to a same value to realize synchronization
among multiple instruments.
Return Format
The query returns INT or EXT.
Example
:SYST:ROSC:SOUR INT /*Sets the system clock source to Internal.*/
:SYST:ROSC:SOUR? /*Queries the system clock source type and the query returns INT.*/
