4. To define the further mask test settings, press the MASKS key on the front panel
(in the ANALYSIS area), and select the "Mask Definition" tab.
5. If necessary, correct the mask segment points you defined graphically in the "Mask
Definition" tab. In the "Region" column of the mask segment, "Inner" is selected.
That means, a mask hit is detected if the signal is inside the segment.
6. Insert another mask segment above the positive pulse:
a) Tap the "Append" button under "Mask segments".
b) In the "Region" column of the new mask segment, select "Upper". In this case,
a mask hit is detected if the signal is above the mask limit line.
c) Under "Definition of segment", tap "Insert" twice to insert two points.
d) Enter the x and y-values to define a line beneath which the values of the posi-
tive pulse should remain.
