Abstract

A signal analysis method is disclosed. The method comprises the following steps: An input signal comprising a symbol sequence is received, wherein the input signal is associated with a first clock signal comprising at least one jitter component. A second clock signal is recovered based on said input signal. At least one jitter parameter is determined that is associated with said at least one jitter component. A jitter signal is reconstructed based on said at least one jitter parameter, wherein said jitter signal is associated with said at least one jitter component. A third clock signal is determined based on said second clock signal and said jitter signal. Further, a measurement instrument is disclosed.
