The graphics consist of 64 points, to have more and

nition
of the curve.
In the “Amplitude curve” graphic (Amplitude section) the ordinate is between
-3 and 3dB in steps of 0.01dB, the abscissa is between -4.2 and 4.2 MHz with
64 points at the same distance.
Similarly in the “Group Delay curve” graphic (Phase section) the ordinate is
between -100 and 100ns in steps of 0.01ns, the abscissa is between -4.2 and
4.2 MHz with 64 points at the same distance.
The red curves are de
ned and edited from user. The gray are curves of default
which are not changeable and are provided from factory.
To change a parameter of the curve just select one point of the graphic and
drag it wherever you desire, it will change the respective table’s value and,
during the dragging operation, a text close to the mouse pointer will show the
current changing value.
It is also possible to change every single value of the precorrection’s curves
simply changing the value inside the four tables under the graphic.
