摘要
A radio-frequency (RF) voltage supply system for supplying a multipole mass spectrometer, in particular a quadrupole mass spectrometer, with the alternating RF voltage used to generate a multipole field, in a secondary circuit excited by means of a primary circuit. The RF voltage supply system has an RF voltage measuring device, by means of which the alternating RF voltage in the secondary circuit is sampled, and a digital measurement value that is dependent on the alternating RF voltage is determined. The RF voltage supply system also has a computing device, by means of which a digital alternating voltage amplitude setting value is determined, taking the measurement value into account. There is also an RF voltage generator, by means of which the alternating RF voltage can be made available with an alternating RF voltage amplitude that is set depending on the alternating voltage amplitude setting value.
