  "textContent": "A calibration device includes a controller configured to communicate a plurality of input voltage signals having different determined frequencies to a first power exchange coil. Also, the calibration device includes a load unit coupled to a second power exchange coil, where the load unit includes at least a first electrical load and a second electrical load. Further, the calibration device includes a voltage sensor configured to measure a plurality of first output voltage signals across the first electrical load and a plurality of second output voltage signals across the second electrical load, and where the controller is configured to determine an optimal operating frequency of a wireless power transfer system based on the plurality of input voltage signals, the plurality of first output voltage signals, and the plurality of second output voltage signals.",
