1. An eddy current, nondestructive inspection system to inspect a test object, comprising:

  • a probe unit including a probe transceiver and located in a position to carry out tests of the test object;

    an NDI unit including an NDI transceiver and configured to operate the probe unit according to predetermined controlling commands including at least one excitation command via a remote communication path established between the probe transceiver and the NDI transceiver;

    the probe unit further comprising;

    at least one transducer element operable for inducing an eddy current in the test object according to the excitation command;

    a receiver circuit for receiving a signal from the test object in response to the eddy current; and

    a microcontroller for executing the controlling command and for transferring data from and to the NDI unit via the probe transceiver; and

    ,the NDI unit further comprising;

    a signal processor configured to process the signal received from the probe unit; and

    a user interface.
