Using the option Head3, it is possible to control three 2-axis scan systems with one USC-3 at the same time. Therefore an extra board called "SEB - Scan head Extension Board" and the corresponding software option is needed. Every scan head uses its own correction file and head matrix with gain, offset and rotation. The positioning signals to each scan head are updated every 30 μs.
