Hi Frank and Gerd,

The signal was slightly over one clock cycle(@150MHz well below fmax), since it was generated by the sampling clock. I've never had any problem with signals like this before. If I triggered on another signal, then the problem signal showed as one clock cycle long. It just couldn't trigger the collection with it.

Regards,

Dan
