Key facts
The R&S®RTP-K136/137 options enable eye analysis of data signals and is one of the most powerful signal integrity measurement tools. Continuously running hardware based clock data recovery (CDR) is used to bit slice the acquired data stream. It supports a maximum nominal data rate of 8 Gbps or 16 Gbps, depending on the selected option. Standard tools such as mask tests, histogram tests or automated eye measurements can be applied to the eye diagram. The powerful eye stripe function helps to trace mask test failures in the acquired waveform.
Configurable 8 or 16 Gbps hardware implemented CDR for continuous analysis
The R&S®RTP offers a unique hardware implemented clock data recovery (HW-CDR) to bit slice a serial data stream with an embedded clock. You can configure the nominal bit rate (between 21 kbps and 16 Gbps) as well as the tracking bandwidth or the relative bandwidth. The hardware CDR in the R&S®RTP continuously follows the drift of the input signal. Traditional eye diagrams use software CDR functions in postprocessing. This is time consuming and requires a PLL settling time per waveform acquisition.

Advanced set of automated eye measurements
Automated measurements make the advanced eye analysis easy to use. Select eye measurement from the 15 measurement categories and utilize all standard analysis functions like statistics, track, histogram and trend display.

Comprehensive mask library
The histogram and the mask test functions can be used for further analysis. A comprehensive library of masks is also available for the eye diagram. Select the right predefined mask for a dedicated standard such as USB, PCI Express and SATA.
Trace back mask test failures
Use the eye stripe function to identify mask test failures in the original acquired waveform. The mask test failure list helps to navigate the zoom window to the part of the waveform that violated the mask. This makes it easier to understand the root cause of signal integrity issues.
