Technique for determining performance characteristics of electronic devices and systems

An apparatus for determining a performance characteristic of an integrated circuit in a signaling system, the integrated circuit having a transmitter, the apparatus to couple to the integrated circuit via a first transmission line, the apparatus comprising:

• a receiver to sample, using a sampling clock, a response on the first transmission line to the transmitting by the transmitter of a digital symbol on one of a first transmission line or a second transmission line, to obtain a digital sequence representing time-variant artifacts from the transmission of the digital symbol;
• and
• logic, including at least one of hardware or software, to determine the performance characteristic based on processing of the digital sequence.
