What WiFiBuddy measures
WiFiBuddy reads the access point information exposed by macOS, including channel, channel width, received signal strength, noise, security, PHY mode, and supported information elements. Availability varies by interface, hardware, macOS version, and permission state.
WiFiBuddy is an observation tool. It does not reconfigure your router or access point.
