Abstract

The invention relates to a measurement system (10) with a signal source (12), an analog to digital converter (24), a numerically controlled oscillator (28) and a mixing stage (30). The measurement system (10) further comprises a periodic averaging circuit in hardware (38) located downstream of the numerically controlled oscillator (28) and the mixing stage (30), wherein the periodic averaging circuit in hardware (38) is configured to sum or average samples obtained over a defined number of buffer lengths, thereby providing at least one output signal. The measurement system (10) has a processing circuit (42) configured to perform a Fourier transform on the output signal. The numerically controlled oscillator (28) together with the mixing stage (30) are configured to shift the frequency of the samples such that picket signal portions of the output signal, processed by the processing circuit (42), are associated with frequency bins in the frequency domain.
