3.6.1.1.2  Asynchronous Triggering 
 
In synchronous trigger mode the incoming trigger and event signals are sampled with 
the SYNC clock which is the DAC sample rate divided by 256 and the input signals need 
to be provided synchronous to the SYNC clock to get a precise output signal.  
 
When using the asynchronous mode, the trigger and event input signals are sampled 
with a clock that is the DAC sampling rate divided by 8. This provides a more precise 
trigger/event to output latency without the need of providing the inputs synchronous to 
any reference.
