Analyze individual components of a single oscilloscope
New options for Rohde & Schwarz's R&S RTO and R&S RTP oscilloscopes can help development engineers gain a deeper understanding of every jitter component of their transmission interfaces. Engineers can now separate jitter into random and deterministic jitter and view the results flexibly for effective debugging. Rohde & Schwarz uses parametric signal model separation algorithms to obtain precise measurements as well as additional additional results.
Rohde & Schwarz has developed an innovative and powerful method to analyze the individual components of jitter, giving circuit designers unprecedented insight that is extremely valuable when debugging high-speed signals.
As data rates increase and voltage swings decrease, jitter in digital interfaces accounts for a large proportion of the signal interval and becomes a potential source of failure. Engineers therefore increasingly need tools that can accurately measure signal jitter, including separating it into its individual jitter components. The new R&S RTO-/RTP-K133 advanced jitter analysis option introduces an analysis method to separate individual jitter components, such as random jitter and deterministic jitter (such as data-dependent jitter and periodic jitter). This approach is based on a parametric signal model that fully characterizes the transmission link under test.
The core advantage of Rohde & Schwarz's approach is that its jitter model includes the complete waveform characteristics of the signal being measured, whereas traditional approaches reduce the data to a set of time-spaced error measurements. Therefore, the new method can obtain consistent measurement data even for relatively short signal sequences, as well as previously unavailable information such as step responses, or the difference between vertical and horizontal periodic jitter. Engineers benefit from deep details of jitter representation, including synthetic eye diagrams, histograms of all individual jitter components, spectral and peak views of periodic jitter, and bathtub plots for estimating bit error rates.
Josef Wolf, senior vice president and head of the oscilloscope division at Rohde & Schwarz, said the R&S RTO-/RTP-K133 option will be welcomed by the market. "We are very proud to bring to market this advanced approach, which is the first real improvement in oscilloscope jitter separation in nearly two decades. With the new Advanced Jitter Component, we can help engineers achieve better results," he said. Its signal jitter signature features unprecedented levels of detail."
This new jitter separation component expands signal integrity debugging capabilities for engineers, complementing the industry's only integrated time domain reflectometry (TDR)/time domain transmission (TDT) measurement method and real-time de-embedding capabilities in a single oscilloscope .
