Evaluation and optimization of a magnetic sensor embedded in a key-fob transponder used in a passive keyless entry system is achieved with a test circuit comprising a signal generator and coil from which a time varying amplitude magnetic field is generated. The magnetic sensor is placed in the magnetic field and the frequency-amplitude characteristics are determined by varying the frequency of the signal generator. Orientation of the magnetic sensor with the magnetic field is also determinative of the characteristics and operation of the sensor. A simulated load and signal strength indicator is temporarily coupled to the output of the magnetic sensor during evaluation of how the sensor will function when connected to the normal input circuits of the PKE transponder.
