1. A device for performing nearfield testing of a phased array system comprising:

  • an input interface configured to receive a modulated output signal of the phased array;

    a phase-locked loop circuit responsive to the received modulated output signal, the phase-locked loop circuit comprising;

    a phase detector;

    a filtering element;

    a variable frequency oscillator, anda feedback loop, anda processor configured to;

    compare an output of at least one of the phase detector and the filtering element with a predetermined phase detector response and an input frequency response of the phase-locked loop, respectively, andbased on the comparison, output at least one of a value indicative of an imparted phase shift and an imparted frequency modulation by the system.
