In order to quickly and accurately measure the performance parameters of the current/frequency conversion circuit (I/F conversion circuit) of inertial navigation system, an I/F conversion circuit test system is designed. Constant current signal, sinusoidal current signal and transient step current signal are provided to the measured system by a program-controlled constant current source. Through the designed frequency measurement circuit, the output frequency signal is measured accurately, the static, dynamic and transient responses of three kinds of I/F converter circuits are analyzed.
