  For beam trans­fer from the KEK-PS Linac to the Booster syn­chro­tron ring and from the Booster to the Main ring, many pulse mag­nets have been in­stalled. It is very im­por­tant for the ma­chine op­er­a­tion to mon­i­tor the fir­ing time, ris­ing time and peak value of the pulsed mag­net cur­rents. It is also very im­por­tant for mag­net tun­ing to ob­tain good in­jec­tion ef­fi­ciency of the Booster and the Main ring, and to ob­serve the last cir­cu­lat­ing bunched beam in the Booster as well as the first cir­cu­lat­ing in the Main. These mag­net cur­rents and beam in­ten­sity sig­nals are dig­i­tized by a dig­i­tal os­cil­lo­scope with sig­nal mul­ti­plex­ers, and then shown on a graphic dis­play screen of the con­sole via a VME com­puter.
