Claim 23:
24. A device set up to emit a first signal (S1) and at least one first further signal (S1w.n) for signal round-trip time measurement or signal runtime measurement or for measuring the phase round-trip shift or for range finding, said device comprising:
at least one PLL for generating the first signal (S1) at a first frequency and the at least one first further signal (S1w) at a first further frequency;
wherein the device is set up to toggle between generation of the first signal (S1) and generation of the at least one first further signal (S1w.n) using knowledge or determination of a phase difference (phi1.n) between the first signal (S1) and the first further signal (S1w.n);
wherein the device is set up to receive a second signal (S2) from a second object and at least one second further signal from said second object;
wherein the device is further set up to determine at least one virtual frequency switching time between a second frequency (f2) of the second signal (S2) and at least one second further frequency (f2w.n) of the at least one second further signal (S2w.n);
wherein at least one second further phase progression of the at least one second further signal (S2w.n) has a first second phase relationship (phi2.1) to a second phase progression of the second signal (S2) at the second object; and
wherein the device is set up to determine from a phase progression of the second signal (S2) received at the device, and of at least one phase progression of the at least one second further signal (S2w.n) received at the device, at least one virtual frequency switching time (t2.1) as a time, at which, at the device, a phase relationship between interpolated or received phase positions of the second and a second further signal (S2, S2w.1) corresponds to the first second phase relationship (phi2.1).
