modelFrequencySweepCurrentSource
Current source with integrated frequency sweep
Extends from Interfaces.TwoPin (Two pins).
Information
This source provides a constant RMS phase current I and phase angle 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.
