OSCAPROBE initiates a large-signal oscillator simulation. See “Nonlinear Oscillator Analysis” for the recommended placement of OSCAPROBE and for details of oscillator analysis.
OSCAPROBE is an ideal source in series with an ideal impedance element. The impedance presents an open circuit at all frequencies other than the fundamental frequency of oscillation.
