The Australian Synchrotron booster accelerates electrons from 100 MeV to 3 GeV in 600 ms. The fractional tune components that were measured are presented in two graphical formats showing the time-resolved measurement of the horizontal and vertical tunes. This experiment demonstrated that the current in the booster was extremely sensitive to the ratio of BF to BD combined-function magnets. Large variations of the fractional tunes were found to follow the differences in the gradients of the BD and BF combined-function magnet ramping curves and with this knowledge, alterations were made to the ramping table increasing the efficiency of the booster by an average of 40%. Rapid fluctuation of the tunes meant that it could not be distinguished during the first 80 ms of the ramp. Multiple side bands to the revolution harmonic were visible during a minimal sweep time of 5 ms, during this first 80 ms.
