nmanzo,
On thing I might suggest is to export your start trigger from the
acquisition device to the generation device in order to gain better
synchronization. When your acquisition device registers a pattern
match, it generates a start event. In the "Dynamic Acquisition
Triggers and Events" section of the help file, your acquisition devices
says that it can export this start event to one of its trigger lines
(PFI, RTSI, etc). You can then connect this to one of the trigger
lines of your generation device and use that as a "Start
Trigger". According to the documentation you can use any of the
PFI or dedicated triggers lines. If you're in PXI you can use one
of the PXI_TRIG lines to easily send the signal from device to
device. Likewise, in PCI, you could use RTSI.
In this fashion, when the pattern is received and matches, the
acquisition will start and generate an event. This event will be
connected to the generation device and will be used to start the
generation. Since this is all hardware timed, your level of
synchronization will be purely based on clock rates and propagation
delays rather than software.
I hope this helps!
Happy Holidays
