The following query returns the "instantaneous" data rate ratio (Actual DRR)
calculated from the counts obtained in the last deci-second. This value is
available even when accumulation is turned off.

Working with PCIe3 SKPOS
Working with PCIe 3.0 SKPOS – Concepts
The Serial BERT provides enhanced capability to perform a receiver (RX) jitter
tolerance test for PCIe3 (PCI
®
Express 3.0). In PCIe3, when RX detects incoming
data correctly, the pattern looped back has the "same" content except the length
