Claim 29:
30. A test system comprising a probe device and an analyzer device, the probe device being arrangeable in a wireless power transfer system that comprises a power transmit device arranged to transfer power over an inductive wireless power transfer interface operating at a transmit frequency, fix, to a power receive device, the wireless power transfer system being of a type which is adapted to transfer information at half duplex using Frequency Shift Keying, FSK, in one direction and Amplitude Shift Keying, ASK, in the other direction,
wherein the probe device comprises at least one pickup coil and further comprises or is operatively connected to said probe analyzer device, and
wherein the analyzer device is configured to:
detect a transferring, at the transmit frequency, fTX, by the power transmit device, of power to the power receive device and, during the transferring:
detect a transmitting, at the transmit frequency, fix, by one of the power transmit device or the power receive device, of a first data packet to the other of the power transmit device or the power receive device using one of two modulation types being FSK or ASK,
detect, during the transmitting, if a signaling condition is fulfilled, a transmitting, at the transmit frequency, fTX, by the other of the devices to said one of the devices, of operational information using the other of said modulation types, and
provide information regarding the detections as output.
