Teledyne LeCroy provides three choices for Response Optimization Mode
selection. These choices combine a frequency and group delay response to
optimize the oscilloscope for particular applications.

Pulse Response - A group delay compensation minimizing preshoot,
this selection most resembles the response of an analog oscilloscope
by controlling group delay to be slightly non-zero at the highest
frequencies. In addition, a fourth-order Bessel frequency response is
implemented.

Eye Diagram - Flat group delay compensation resulting in equalized
preshoot and overshoot. This selection improves the symmetry of
serial eye diagrams. In addition, a fourth-order Bessel frequency
response is implemented.
