4.9.14. Modifying a Profile using Variables
The FSP Amplifier includes functionality that allows you to stretch
and shift a profile without having to redefine each segment. Simply
by adjusting the values of variables, you can:
♦ Stretch the profile horizontally by adjusting the Master scale.
♦ Stretch the profile vertically by adjusting the Slave scale.
♦ Shift the profile horizontally.
♦ Offset the profile vertically.
4.9.14.1. Profile Scaling
The Master scale can be adjusted by multiplying it by a fraction
A/B. If A/B is larger than one, the profile will be stretched. If A/B is
less than one, the profile will be contracted.
♦ A, the numerator, is defined by the variable
ECAM_Master_scale_num.
♦ B, the denominator, is defined by the variable
ECAM_Master_scale_den.
For example, if a scaling factor of 2/3 was applied to the profile
shown below, the Master axis would be contracted by a third.
