摘要：
The present invention relates to a processing of a signal under test in order to compensate frequency variations in the signal under test. For this purpose, the signal under test is mixed with a further digital signal. A frequency of the further signal which is used for mixing with the signal under test may be adapted in real-time according to frequency variations in the signal under test.
