1. A method for digital triggering a recording of one or more signals on a digital oscilloscope comprising:

  • implementing a level comparison in order to determine a triggering time respectively between two successive sampled values of a reference signal on the digital oscilloscope and a threshold value; and

    determining at least one additional sampled value of the reference signal between the two successive sampled values of the reference signal,wherein the at least one additional sampled value of the reference signal between the two successive sampled values of the reference signal is calculated by interpolation, if the threshold value is disposed either above both of or below both of the two successive sampled values of the reference signal, andwherein the at least one additional sampled value is used in the determining of the triggering time between the two successive sampled values.
