Basic Operation
Using the Graphical User Interface
Synchronizing Two N8241/2A Modules
Internal Clock Synchronization Using Continuous Mode
When synchronizing two modules using the internal clock, one unit is designated as
the Master and the other unit is designated as the Slave. The Master unit sources the
sample clock and the sync clock signals. These signals are split and fed to the
synchronized modules (the Master as well as the Slave).
The internal sample clock operates at 1.25 GHz and provides the final retiming of
the analog output from each AWG. Any skew in the sample clock cable delays
between the modules will result in the same skew in the analog outputs.The sample
clock signal is split with a matched passive divider and the cable lengths are
matched. The resulting skew is small and repeatable.
