"... overall the phantom exceeds all previously published sideband suppression figures.

The built-in audio oscillator allows 100% reproducable audio test signals to be injected for frequency abscissa calibration checking whilst any waveform lying within the wide audio bandwidth of the phantom may be injected via the Dynamic Imaging audio phasing board."
