A signal probe apparatus having a probe tip, a grounding attachment, a main body portion and a connector for use with a signal measuring device. The probe tip and the grounding attachment are coupled by way of first and second signal lines to the connector for supplying signals therefrom to the signal measuring device. A plurality of circuit elements, such as resistors, are connected between the second signal line and a third line in the connector; and switch means located on the main body portion enables a predetermined circuit value, for example, the resistance between the second and third lines, to be selectively changed to a respective value which corresponds to a respective one of several predetermined functions which may be performed by the signal measuring device. The selected circuit value is detected by the signal measuring device and the corresponding function is thereafter implemented.
