Thank you for attention. I have already tried to use the example you
suggested. The problem is I need not only a reference trigger, but a
continuous acquisition, too. I have read somewhere in the on-line user
manuals that continuous acquisition is not suitable with reference
trigger. Is it true? Do I really have no possibility of doing what I
need and solve my problem with my PXI-4472? You can look at my other
recently posted questions to get an idea of my problem. Thank you and
hope to hear of you soon. Giulia
