Abstract
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.
Claims18
A measuring device for phase-coherent analysis of frequency-hopping signals, the measuring device comprising:
- a signal acquisition unit obtaining an In-phase/Quadrature-phase-signal (I/Q-signal), and
- an analyzing unit receiving the I/Q-signal from the signal acquisition unit, detecting hop occurrences at nominal hop frequencies based on the provided I/Q-signal, specifying at least one common reference frequency with respect to the hop occurrences, and specifying at least one common reference phase with respect to the hop occurrences detected by the analyzing unit.
