Chapter 2 Command System RIGOL
DG800 Programming Guide 2-155
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.*/
