1. For use with a system comprising a phase offset device and providing a plurality of phase-shifted signals to a corresponding plurality of system ports, a method for determining phase offsets necessary for a phase offset device to compensate for differences in the system components up to approximately the system ports, the method comprising:

  • providing predetermined phase offsets for at least predetermined system ports to the phase offset device;

    driving each of the system ports with a signal;

    adjusting the provided phase offset for each predetermined system port until a predetermined phase condition is detected for the predetermined system port with respect to a first system port; and

    reducing the provided phase offset for a predetermined system port by the predetermined phase condition for that predetermined system port to determine the compensating phase offset for that predetermined system port with respect to the first system port.
