Displaying or storing complex data seems to work just fine here.  What I
think is going on is that the data being sent from the instrument is a
two-dimensional array that is simply read into real arrays on VEE, and so
is not a set of complex numbers on VEE.

If that is the case, you need to run the real data and the imaginary data
arrays into the Build Complex (Data -> Build Data -> Build Complex) object
to get a true Complex array.

You can find out what data types things are by clicking on the output pin of
the object it comes out of.
