Clock Source Setting
DG5000 provides a 10 MHz internal clock source and also accepts external clock
source input from the [10MHz In] connector at the rear panel. It can also output a 10
MHz clock source from the [10MHz Out] connector for other device to use.
Press Utility  System  CLK to select “Internal” or “External”. The default is
“Internal”.
By setting clock source, synchronization can be realized between two instruments or
more. “Align Phase” function is disabled when two instruments are synchronized as it
only applies to align the phase relationship of the two channels in one generator. The
phase relationship between two synchronous channels of different instruments can be
changed by modifying the “Start Phase” of each channel after synchronization.
Sync methods for two or several instruments:
 Synchronization between two instruments:
Connect the [10 MHz Out] connector of Generator A (“Internal” clock) to the
[10MHz In] connector of Generator B (“External” clock) and set the output
frequencies of A and B as a same value to realize synchronization for two
instruments.
 Synchronization among multi-instruments (Method 1):
Connect the [10 MHz Out] connector of Generator A (“Internal” clock) to the
[10MHz In] connector of Generator B (“External” clock), then connect the [10
MHz Out] connector of Generator B with the [10MHz In] connector of Generator C
(“External” clock), etc. finally set the output frequencies of all the generators as a
same value to realize synchronization for multi-instruments.
