An electronic test instrument for facilitating the analysis of a machine's response to cyclic perturbations in one of its control parameters and for adjusting the control parameter based upon the observed response so as to optimize the machine's performance. The instrument permits manual control over the rate and magnitude of the perturbation, the amount of bias, i.e., the deviation of the actual operating point from the optimum, and the upper and lower limits between which correction is permissible. To prevent undue hunting of the control parameter about an operating point, the instrument includes a buffering network that requires that the system call for a predetermined number of control parameter adjustments in a given direction before an actual correction will be effected. The number is selectable by manually settable switches.
