Abstract

An approach is provided for digital triggering a recording of one or more digitized signals on a digital oscilloscope by means of carrying out a level comparison for determining a triggering instant in each case between two successive sample values of a reference signal and a threshold values. According to the approach, at least one additional sample value of the reference signal is determined between two sequential samples of the reference signals by means of interpolation.
