METHOD AND DEVICE FOR MEASURING WEAK INBAND INTERFERENCE

摘要

A measurement device for measuring a first input signal which is part of a measurement signal (31) comprises a measurement unit (28) set up for measuring the first input signal within a signal (371, 2 ) derived from the measurement signal (31), a transformation unit (24) set up for transforming the measurement signal (31) or a signal (331, 2) derived from the measurement signal (31) into the frequency- domain resulting in a first frequency-domain signal (341), a filter unit (25) set up for removing components of the first frequency-domain signal (341) which correspond to a second input signal which is part of the measurement signal (31), resulting in a first filtered signal (351), and an inverse transformation unit (26) set up for transforming the first filtered signal (351) into the time-domain resulting in a first time- domain signal (361).
