Abstract
The invention relates to a method and an arrangement for performing triggering and for determining a triggering moment. In the solution, a unipolar electrical pulse of a detector () is converted between the detector () and a first amplifier () succeeding the detector into at least one bipolar electrical oscillation. The bipolar electrical oscillation is amplified with at least one amplifier () and triggering is performed at a zero level between the extreme values of the bipolar electrical oscillation. In addition, a triggering moment is determined, at which the amplified bipolar electrical oscillation crosses the zero level between its extreme values.
