Using the option Head2, it is possible to control three 2-axis scan systems with one USC-2 at the same time. Therefor an extra board called "SEB - Scanhead Extension Board" and the corresponding software option is needed. Every scanhead uses its own correction file and head matrix with gain, offset and rotation. The positioning signal to each scanhead is updated all 30 μs.
