A drive-sense circuit module includes at least one regulated source circuit coupled to a load, and to a loop correction circuit. The regulated source circuit generates a drive signal, which has a regulated characteristic and a controlled characteristic. At least one reference circuit applies a reference signal to the loop correction circuit that establishes a reference value of the controlled characteristic. The loop correction circuit senses an effect of one or more load characteristics on a sensed value of the controlled characteristic of the drive signal and generates a comparison signal based on the sensed value and the reference value of the controlled characteristic. A regulation signal is generated based on the comparison signal and used to regulate the regulated characteristic of the drive signal. A control module controls the regulated source circuit and the loop correction circuit to iterate through at least a first combination and a second combination of regulated characteristics and controlled characteristics.
