Claim 0:
1. A system for testing of wireless power equipment in the form of a wireless power transmitter device and a wireless power receiver device, the system comprising:
a probe device comprising:
at least one pickup coil, 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, and
an interface for providing the electric signals generated by the pickup coil to an analyzer device;

an analyzer device comprising:
an interface for receiving the electric signals generated by the pickup coil of the probe device, when the probe device is placed between the surface of the housing of the wireless power transmitter device and the surface of the housing of the wireless power receiver device and captures the electromagnetic signals exchanged between the wireless power transmitter and receiver devices, and
a processing unit coupled to the interface and configured for processing of the received electric signals; and

means connected with the pickup coil of the probe device and adapted for causing manipulation of the electromagnetic signals exchanged between the wireless power transmitter and receiver devices,
wherein the processing unit of the analyzer device is configured to analyze the behavior of the wireless power receiver device and/or the wireless power transmitter device in reaction to the manipulation, by the means for causing manipulation, of the electromagnetic signals exchanged between the wireless power transmitter and receiver devices, by examining the electric signals generated by the pickup coil of the probe device.
