INVERTED. The setting is performed via jumper for the N568 LC and by shortcircuiting two pins for
the N568 B; refer to Fig. 3.1 for the components’ location.

3.2.3 OUTPUT POLARITY SETTING
This setting can be done either via Manual Controller or via H. S. CAENET. It allows the internal
electronics to operate at its best on the signals. It must be set according to the input signal polarity
and the output configuration setting, e.g. if the input signal is Positive and the desired Output
Configuration is chosen as Inverted, the output polarity is Negative and this information must be
transferred to the module's internal electronics (optimization of the Baseline Restorer stage).
3.2.4 SHAPE SETTING
This setting can be done either via Manual Controller or via H. S. CAENET. The shaping time can be
selected in 4 steps (0 to 3) among the following: 0.2 µs, 1 µs, 3 µs and 6 µs.
