A measuring device for phase-coherent analysis of frequency-hopping signals is provided. The measuring device comprises a signal acquisition unit and an analyzing unit. Whereas the signal acquisition unit is configured to obtain an In-phase/Quadrature-phase-signal (I/Q-signal) and to provide said I/Q-signal for the analyzing unit, the analyzing unit is configured to detect hop occurrences at nominal hop frequencies based on the provided I/Q-signal. In addition to this, the analyzing unit is further configured to specify at least one common reference frequency with respect to the hop occurrences.
