description A scanning probe for a coordinate measuring machine with inductive position sensor signal gain control is provided. The scanning probe includes a stylus position detection portion with field generating and sensing coils, and for which corresponding output signals are indicative of a position of the probe tip of the stylus. Signal processing and control circuitry is configured to implement different operating regions, such as a central high gain operating region which corresponds to a central probe tip position range, as well as other lower gain operating regions, and for which transition operations may be performed for adjusting the gain. In various implementations, transition operations for adjusting a gain may include operations such as: adjusting power to a field generating coil configuration; adjusting a gain of a front end amplifier; altering characteristics of sensing coils; adjusting an input range of an analog to digital converter, etc.
