PCIe mid-bus probe
U4322A - Keysight Technologies
Keysight's PCIe 3.0 analyzer uses Keysight's unique ESP (Equalization Snoop Probe) technology, with the ability to tune the equalization algorithm used according to the type of channel the analyzer is monitoring. This ensures that the data captured in the analyzer is exactly what is on the wire. Without this capability, at 8GT/s, there is a high likelihood of misrepresentation of the data on the bus, which can lead to wasted hours, if not days in the validation cycle.
