Scan also contains the necessary hardware for
controlling the x/y electron beam deflection as well
as two separate digitizers for the image signals of
the electron microscope (EM).

spectrometry data acquisition is provided for
advanced line scan and element mapping. Digital
signal processing supports the server computer in
time critical tasks. Control signals for hardware scan
switching are provided as well.
Switch Box. The opti
