| 摘要 |
The invention refers to analyzing a digitally modulated test signal received from a device under test -DUT-, comprising providing a first sampled signal by assigning a first sequence of digital values as result of a level comparison of the test signal with a first threshold at first successive timing points, generating a first masking signal indicating matches between a second sequence of digital values expected from the DUT and one or a plurality of first data patterns, and analyzing the first sampled signal in conjunction with the masking signal.
