Abstract: The frequency-mask trigger unit comprises n trigger machines, where n?2, in order to evaluate a total of n signal paths. In this context, the n trigger machines are connected to an evaluation unit. For this purpose, at least one trigger range is transferred to the n trigger machines. Moreover, a plurality of result vectors of a signal under analysis transformed into the frequency domain are transferred via the n signal paths to the n trigger machines. Finally, each of the n trigger machines checks whether at least one of the plurality of result vectors of the signal under analysis transformed into the frequency domain infringes the at least one trigger range.
