Oscillator Probe Syntax

To enable oscillator analysis, the circuit must include one oscillator probe device for each unknown frequency to be calculated. The netlist syntax for the oscillator probe device is:

Rxxx n+ n- OSC_PROBE=1 A=val FREQ=val

The oscillator probe element can have any name beginning with “R”. The OSC_PROBE parameter is required to distinguish the oscillator probe from a resistor.

The FREQ parameter specifies a frequency to be used as the initial guess for the unknown oscillation. The A parameter specifies a voltage to be used in the calculations.

The probe behaves like an oscillating voltage source with amplitude given by the parameter A at the frequency given by the parameter FREQ. At all other frequencies, the probe current is zero. The default for parameter A is 10mV. The default for parameter FREQ is 1e6Hz.
