Hi, I have a pxi 5922, an arbitrary waveform generator 5412. They are in sync due to Tclk. The issue I have is that I can't capture the start of the function generators output. I have tried different reference positions for the scope, but am unable to shift it to the start. I have tried having both the function generator and digitizer as the master, this does not appear to help my issue. Is there something else I could try to capture the start of the func gen output while using Tclk. Cheers,Brett

So, the 5922 has a delta sigma converter on it which will cause a sample delay when synchronizing with other cards, the same as our DSA cards. This is the sample delay we are seeing and there is nothing synchronizy we can do to get rid of it. What I would recommend is to generate 62 "junk" samples at the beggining of your waveform.

Thanks for the response Doug,

That is what I ended up doing in the end.
