1. A method of determining a figure of merit of at least one component under test within a signal chain having several components, wherein the signal chain is an internal and/or external signal chain, wherein the method comprises at least the steps of:
capturing a measurement signal at a port of the signal chain,
determining an overall figure of merit of the signal chain, and
repeatedly capturing the measurement signal at the port of the signal chain while altering at least one setting of one of the several components of the signal chain per repetition, wherein the overall figure of merit of the signal chain is determined for each repetition, and wherein the at least one setting is altered such that the contribution of the respective component under test to the overall figure of merit of the signal chain is increased with respect to contributions of remaining components of the signal chain.
