Abstract: A test and measurement system includes a radio frequency antenna structured to receive a wireless carrier signal generated by an NFC vicinity coupling device and to receive load-modulated wireless carrier signals generated by one or more vicinity integrated circuit cards in response to the wireless carrier signal, and a response detector structured to determine if any load-modulated wireless carrier signals generated by one or more vicinity integrated circuit cards were received by the antenna. The response detector may use cross-correlation to determine if the load-modulated wireless carrier signals are present.
