Abstract

A method for setting voltage resolution in particle beam measuring devices wherein band width of a measured signal processing is modified. In order to set a desired voltage resolution simply, reliably, and with high precision, a signal noise of the measured signal is measured. This signal noise is compared to a desired value for the measured signal resolution, and the band width of the measured signal processing is modified such that the signal noise of the measured signal is less than or equal to the desired value for the measured signal resolution.
