Disclosed is a signal analyzer that can receive a signal generated by an external system. The signal has a plurality of frequency components. The signal analyzer generates a suppressed phasor domain representation of the signal by selectively removing at least one component for use as a reference. The signal analyzer then displays the suppressed phasor domain representation of the signal. In one embodiment, the signal analyzer removes the component of greatest magnitude. The signal analyzer can also (or alternatively) remove a user selected component. In addition to the suppressed phasor domain, the signal analyzer can simultaneously display the frequency domain, the time domain, the numerical domain, and/or the modulation domain.
