Hello,
What is the name of the example you are running?
Also what device is the PXI-8260?
If I understand your application correctly, you are routing an external
clock through the backplane of your chassis? and then connect a
trigger signal onto to PFI0?
What chassis are you using?
You said that the data is inconsistent, can you take a look at your external
clock signal and verify its integrity?
