6.2.3 Editing „Ramp“
A „Ramp“ is defined as a linear change of either voltage, angle, frequency, etc. as a function of time.
Remarks:
If several coupling paths are selected at SURGE or
EFT, the ramp will be performed for each coupling
path.
e.g.
L-GND; N-GND; PE-GND
6.2.3.1 Definition of a ramp
The steps of a „Ramp“ depend on the ramp time and the difference between the nominal and start- values.
