  • Patent number: 11956029
    Abstract: A system (100) for testing of wireless power equipment in the form of a wireless power transmitter device and a wireless power receiver device is disclosed. The system (100) has a probe device (110) and an analyzer device (130). The probe device (110) has at least one pickup coil (112), the pickup coil being adapted to be placed between a surface of a housing of the wireless power transmitter device and a surface of a housing of the wireless power receiver device to generate electric signals by capturing electromagnetic signals exchanged between the wireless power transmitter and receiver devices pursuant to a wireless power transfer protocol. The probe device (110) also has an interface (114) for providing the electric signals generated by the pickup coil (112) to the analyzer device (130). The analyzer device (130) has an interface (132) for receiving the electric signals from the probe device (110).
