You may export it with this

But the GUI might not like too many figures open, you will need to close the figure after export.

Please note, Ex is a 4 dimension matrix of x,y,z and f. For a plane monitor, it effectively has 3 dimensions. 300 frequency points seem to large. Please make sure you need all the data and your computer is powerful enough.
