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 (106, 118) is converted between the detector (106, 118) and a first amplifier (108, 120) succeeding the detector into at least one bipolar electrical oscillation. The bipolar electrical oscillation is amplified with at least one amplifier (108, 120) 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.
