86100CU-400 and Keysight 86100DU PLL and Jitter Spectrum Measurement Software

Data Sheets

Option 400 for the 86100 Series Infiniium DigitalCommunication Analyzer(DCA-J or DCA-X) is an advanced software application that makes fast, accurate, and repeatable phase locked loop (PLL)/jitter transfer measurements, using a precision jitter source and receiv

Pre-configured setups and automated report generation for

  • PCI Express PLL compliance measurements approved by the PCI-SIG
  • SONET/SDH jitter transfer testing
  • PCI Express reference clock measurements
  • SSC modulation analysis, and more

The Microsoft Office Excel-based application runs on an external PC, or a Keysight Technologies, Inc. 86100C/D DCA, with Microsoft Excel installed.

 

Fast and accurate phase locked loop (PLL) measurements

Phase locked loops are used in a variety of applications including clock extraction circuits and multiplier/dividers. PLLs are commonly used to manage or create timing across the system and can have a significant impact on the overall jitter performance. Accurate knowledge of PLL performance is essential to a good design.

In a matter of seconds, the system accurately characterizes PLL bandwidths of over 80 MHz, a precision measurement that could take an hour or more if performed manually. The software includes an industry-first collision-avoidance technique to ensure the jitter source avoids testing at periodic jitter frequencies inherent in the device, resulting in precise and repeatable PLL measurements.

Flexible configuration to accommodate many device types

The system can also be easily customized for unique PLL applications. Its flexible architecture can test inputs/outputs from 50 Mb/s to 13.5 Gb/s (data signals) or 25 MHz to 6.75 GHz (clock signals).

  • Transmitters
  •  Clock recovery
  • Repeaters
  •  Clock multipliers/dividers

Make sure your device is compliant

The application includes pre-configured setups and automated reports for common standards.

The PCI-SIG has approved the system for PCI Express PLL compliance testing.

Built-in compliance reports

The reports can also be easily customized for your specific needs.

Simultaneous waveform measurements provide confidence in your results

86100 Series DCA, well known for its speed, accuracy, and ease-of-use as a jitter measurement tool, also allows you to observe the device’s output waveform while making the PLL measurement. This capability helps ensure you are testing the PLL under the correct setup conditions; such as pre-emphasis levels, data pattern, bias settings and data rate.

Gain insight into root cause of jitter

In addition to PLL measurements, the Option 400 software provides valuable insight into the root causes of jitter by making jitter spectrum/phase noise measurements on data and clock signals.
