Jitterlyzer

The FS5000 Jitterlyzer performs physical layer serial bus jitter evaluation. It can inject controlled jitter and measure the characteristics of incoming jitter. When teamed with a logic analyzer or protocol analyzer, it can correlate these measurements with protocol analysis. Physical-layer tests can be performed while the system under test is processing live bus traffic.
Jitter measurements.
The FS5000 measures jitter in two categories:
Timing.
"There are four different timing measurements":
Eye.
"There are three different eye measurements"
