A multi-beam particle beam system includes a multi-aperture plate having a multiplicity of apertures. During operation, one particle beam of the plurality of particle beams passes through each of the apertures. A multiplicity of electrodes are insulated from the second multi-aperture plate to influence the particle beam passing through the aperture. A voltage supply system for the electrodes includes: a signal a generator to generate a serial sequence of digital signals; a D/A converter to convert the digital signals into a sequence of voltages between an output of the D/A converter and the multi-aperture plate; and a controllable changeover system, which feeds the sequence of voltages successively to different electrodes.
