modelFrequencySweepCurrentSource
Current source with integrated frequency sweep
Extends from Interfaces.TwoPlug (Two plugs with pin-adapter, reference connection and declaration of voltage and current).
Information
This source provides polyphase constant RMS phase currents I and phase angles phi,
whereas the frequency sweeps from
fStart to fStop with duration. The frequency sweeps such
way that on a logarithmic frequency scale, the frequency curve appears linear.
