Using the FibreChannel Option
Using the FibreChannel Option Overview
PCI Express (PCIe) is a serial computer expansion card interface standard developed to replace parallel PCI, PCI-
X, and AGP standards. It is now pervasive in computing systems, and its earliest generation (PCIe 1.x) is
becoming more common in embedded systems. PCIe utilizes point-to-point connections and typically consists of
multiple lanes of both transmit (Tx) and receive (Rx) datastreams, with data being "striped" across multiple
datastreams to achieve higher data transmission rates than a single lane could provide.
Correcting Poor Signal Quality or Inverted Signals
It is important to provide a high quality signal when using the Serial Decode package; this is true for PCI Express
decode as well as all the other types. If bits cannot be interpreted correctly the decode, of course, is bad. Notice
how the relatively good quality of the signal shown in the speed change screen-shots towards the end of
