Claim:
1. A printed circuit board for extracting a signal being exchanged between a device under test and an automatic test equipment, the printed circuit board comprising: a plurality of first terminals for contacting terminals of a socket of the device under test; a plurality of second terminals for contacting terminals of a test fixture of the automatic test equipment which are adapted for contacting the terminals of the socket of the device under test; a plurality of transmission lines connecting the plurality of first terminals and the plurality of second terminals; and an extracting circuit electrically coupled to one of the plurality of transmission lines and configured to extract the signal being exchanged between the device under test and the automatic test equipment over the one transmission line in order to provide an extracted signal, wherein the extracting circuit comprises a resistor or a resistor network, wherein a loss added on the signal being exchanged between the device under test and the automatic test equipment over the one transmission line due to the presence of the printed circuit board is smaller than 6 dB.
