Abstract

A signal processing module (18) for a measurement instrument (12) is described. The signal processing module (18) comprises an analysis module (24), a measurement input (16), and at least two parallel measurement channels (26, 28). The at least two parallel measurement channels (26, 28) are configured to process the input signal, thereby generating a first complex-valued measurement signal and a second complex-valued measurement signal. The analysis module (24) is configured to determine a first error quantity associated with the first complex-valued measurement signal and a second error quantity associated with the second complex-valued measurement signal. The analysis module (24) is configured to determine a complex-valued average signal, wherein the complex-valued average signal corresponds to a combined average of the first complex-valued measurement signal and of a complex conjugate of the second complex-valued measurement signal. The analysis module (24) is configured to determine a combined error quantity based on the complex-valued average signal. The analysis module (24) is configured to determine a comparison quantity based on the combined error quantity as well as based on the first error quantity and/or the second error quantity, wherein the comparison quantity is indicative of a relative magnitude of the combined error quantity compared to the first error quantity and/or the second error quantity. Further, a measurement instrument (12) is described.
