Abstract
Disclosed is a device that can be used to obtain voltages for the biasing of the electrodes used to deflect the electron beam emitted by a cathode of an X-ray tube. Four DC voltages .+-.V.sub.1 and .+-.V.sub.2 are generated and applied to a mixing circuit in which they are added by using diodes to floating reference pulse voltages .+-.V.sub.3 so as to obtain voltages VS.sub.1, VS.sub.2, VS'.sub.1, VS'.sub.2 for the charging of capacitors such that: EQU VS.sub.1 =V.sub.3 -V.sub.1 and VS.sub.2 =-V.sub.3 +V.sub.2 EQU VS'.sub.1 =-VS.sub.3 +V.sub.2 and VS'.sub.2 =V.sub.3 -V.sub.1
