The secondary truncation technique is employed for obtaining approximate solutions of a system of truncated differential equations for a single-loop automatically biased parametric oscillator. Approximate analytic equations are obtained for describing the establishing of oscillations in a parametric oscillator with allowance for simultaneous action of three amplitude limiting mechanisms (without allowance for the response lag of the automatic biasing network). Some analytic calculations are compared with numerical calculations and with experimental results.
