18 Jitter analysis and clock data recovery
Jitter describes the timing errors in a system. It is a significant and undesired factor in
high-speed serial communication designs because it causes transmission errors.
R&S RTP provides different options for analyzing jitter:
General jitter analysis (R&S RTP-K12)
The jitter analysis option R&S RTP-K12 provides common analysis and visualization
tools for signal integrity analysis and jitter characterization:
●
Automated jitter measurements in time domain like period, frequency, cycle-to-
cycle jitter and skew
●
Track graph of jitter measurement results
●
Jitter spectrum
●
Eye mask definition and analysis
●
Software-based clock data recovery
See: Chapter 18.1, "Jitter measurements (Option R&S RTP-K12)", on page 1013.
Advanced jitter analysis (R&S RTP-K133)
The advanced jitter analysis option provides tools for detailed analysis including:
●
All functionalities provided with option R&S RTP-K12
●
All data for total jitter, random jitter, periodic jitter, data-dependant jitter and deter-
ministic jitter.
●
Allows separation into horizontal and vertical components.
●
Provides options for extensive result presentation, like histogram, spectrum, track,
jitter bathtub graphics and synthetic eye diagram.
See: Chapter 18.2, "Advanced jitter and noise (option R&S RTP- K133/K134)",

Advanced jitter and noise analysis (R&S RTP-K134)
The advanced noise analysis provides tools for detailed jitter and noise analysis includ-
ing:
●
All functionalities provided with option R&S RTP-K133
●
All data for total noise, random noise, periodic noise, data-dependant noise and
deterministic noise.
●
Allows separation into horizontal and vertical components.
●
Provides options for extensive result presentation, like histogram, spectrum, track,
noise bathtub graphics and synthetic eye diagram.
The different ways for analyzing jitter and noise are described in the following chapters.
In addition, option R&S RTP-K140/K141 provides hardware-based clock data recovery.
The resulting clock edge stream can be used as trigger source for the high speed
serial pattern trigger.
