  • Concept for extracting a signal being exchanged between a device under test and an automatic test equipment
    Patent number: 9568498
    Abstract: A printed circuit board has first terminals for contacting terminals of a socket, second terminals for contacting terminals of a test fixture of an automatic test equipment, which are adapted for contacting the terminals of the socket of a device under test, transmission lines for connecting the first terminals and the terminals, and an extracting circuit electrically coupled to one of the transmission lines and configured to extract the signal being exchanged between the device under test and the automatic test equipment. The extracting circuit has a resistor or an electrical 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.
