System Set
Power On Set
Set the configuration to be used when the instrument is powered on the next time to
“Default” or “Last”. The default setting is “Default”.
 Last: includes all system parameters and states, except channel output state
and clock source.
 Default: denotes the factory defaults except certain parameters (such as
Language).
Press Utility  System  Power On to select the desired configuration type. This
setting is stored in non-volatile memory and will not be influenced by the Set To
Default operation.
Clock Source
DG1000Z provides an internal 10MHz clock source and accepts external clock source
from the [10MHz In/Out] connector at the rear panel. It can also output clock
source from the [10MHz In/Out] connector for other devices.
Press Utility  System  Clk Src to select “Int” or “Ext”. The default is “Int”. If
“Ext” is selected, the instrument will detect whether a valid external clock signal is
input from the [10MHz Out/In] connector at the rear panel. If no valid clock
source is detected, the prompt message “Not detect a valid external clock!” would be
displayed and the clock source would be switched to “Int”.
You can synchronize two or more instruments by setting the clock source. When two
instruments are synchronized, the “Align Phase” function can not be used. “Align
phase” is only applicable to be used to adjust the phase relation between two output
channels of the same instrument and can not be used to change the phase relation
between the output channels of two instruments. Of course, you can change the
phase relation between two instruments by changing the “Start Phase” of each
channel.
Sync methods for two or more instruments:
 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 as 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
