The digital scan generator provides various scan modes (up/down & up only, forward/backward & forward only), defi nition of tip velocity (con-stant scan speed, constant line frequency) and instantaneous start/stop and re-start. All imaging parameters such as size, position, rotation and speed can be changed 'on the fl y' using advanced mouse functionalities at the online scan frame display or at the virtual representation of the current scan area. MATRIX superior hardware technology allows for 200 kHz acquisition rate (5 Եs per image pixel) which equals to 10 images per second at 100x100...

The intuitive MATRIX user interface enables newco-mers as well as experts to operate with high effi -ciency. Windows can be easily adapted to individual user requirements and all available input and data fi elds can be freely assigned to available or newly generated windows. Communication to the hard- ware is virtually instantaneous. Parameter changes are applied at any scan position with latency times in the 10 ms range, virtually getting the operator 'into touch' with probe and sample. ѕ Direct Accessible MATRIX Raw Data for self-written data processing routines, for self-written...
