118 SDG1000X User Manual
2.13.8 Clock Source
The SDG1000X provides an internal 10MHz clock source. It also can accept
external clock source form the [10 MHz In/Out] connector at the rear panel. It
can also output the clock source from the [10 MHz In/Out] connector for other
devices.
Press Utility → Page 1/2 → Clock → Source to select ―Internal‖ or ―External‖
and select ―Enable‖ or ―Disable‖ 10MOut. If ―External‖ is selected, the 10MOut
will be set to ―Disable‖ and the instrument will detect whether a valid external
clock signal is input from the [10MHz In/Out] connector at the rear panel. If not,
the prompt message ―No external clock source!‖ would be displayed and the
clock source would be switched to ―Internal‖.
Sync methods for two or more instruments:
Synchronization between two instruments
Connect the [10MHz In/Out] connector of generator A (using internal clock) to
the [10MHz In/Out] connector of generator B (using external clock) and set the
output frequencies of A and B as a same value to achieve synchronization.
Synchronization among multiple instruments
Divide the 10MHz clock source of a generator (using internal clock) into
multiple channels, and then connect them to the [10MHz In/Out] connectors of
other generators (using External clock), and finally set the output frequencies
of all the generators as a same value to achieve synchronization.
