source is detected, the prompt message "Not detect a valid external clock!" would
be displayed and the clock source would be switched to "Int".
Users can also synchronize two or more instruments by setting the clock source.
When two instruments are synchronized, the "Align Phase" function cannot be
used. The "Align phase" function can only be used to adjust the phase relation
between two output channels of the same instrument and cannot be used to
change the phase relation between the output channels of two instruments. Users
can change the phase relation between two instruments by change 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 (set the clock source
to "Int") to the
[10MHz In/Out] connector of Generator B (set the clock
source to "Ext") and set the output frequencies of the two instruments as a
same value to realize the synchronization between the two instruments.

Synchronization among multi-instruments:
Divide the 10MHz clock source of a generator (set the clock source to "Int")
into multiple paths; then, connect them to the
[10MHz In/Out] connectors
of the other generators (set the clock source to "Ext") respectively. Finally, set
the output frequencies of all the generators as a same value to realize the
synchronization among multi-instruments.
