We report on the automation of these measurements at CERN that permit efficient set-up of the cooling loops in the anti-proton decelerator (AD) and enables insight into the bandwidth (nominal frequency range of 850 MHz to 1.7 GHz) of the overall system for the longitudinal, horizontal and vertical cooling at the two different beam momenta of 2 GeV/c and 3.5 GeV/c. Data collected in machine development sessions can be used to identify areas of improvement and will be indispensable in defining the planned path for consolidation and upgrade of the system. It allows the comparison of the bandwidth with the computed shunt impedance of the currently used kickers. The unwanted interplay between the three different planes of cooling is also evaluated and will help to define improvements in the system for the future.
