As part of the 5 MW Eu­ro­pean Spal­la­tion Source (ESS), the Medium En­ergy Beam Trans­port (MEBT) was de­signed, as­sem­bled, and in­stalled in the tun­nel since May 2020 by ESS-Bil­bao. This sec­tion of the ac­cel­er­a­tor is lo­cated be­tween the Radio Fre­quency Quadru­pole (RFQ) and the Drift Tube Linac (DTL). The main pur­pose of the MEBT is to match the in­com­ing beam from the RFQ both trans­versely and lon­gi­tu­di­nally into the DTL. The lon­gi­tu­di­nal match­ing is achieved by three 352.209 MHz RF buncher cav­i­ties. In this paper, we focus on the RF con­di­tion­ing process for each set of power cou­pler and buncher cav­ity. For this pur­pose, dif­fer­ent tools were de­vel­oped on EPICS and Python as well as elec­tron­ics hard­ware such as Fast In­ter­lock Mod­ule (FIM) and tim­ing sys­tem. These tools served to au­tom­a­tize both the cav­ity fre­quency tun­ing and the power ramp-up process and will be de­scribed in de­tail in the fol­low­ing sec­tions.
