Quick Sweep is a very fast 1,000 – 60,000Hz sweep with a click before each
sweep, designed to offer a visual reference as to the high frequency
performance of your STL or exciter. If you were to connect an oscilloscope
to a calibrated tuner with MPX output (such as the Belar Wizard, for
example) this is the shape you would see if your STL or exciter had a flat
