Phase noise is unintentional phase modulation on a signal that spreads the spectrum and degrades performance in many RF applications.

Rohde & Schwarz has many test instruments and solutions for highspeed digital design including oscilloscopes, spectrum and phase noise analyzers, signal generators, vector network analyzers, and power supplies.

A challenge of high-frequency design is overcoming signal integrity issues, especially with 112G SerDes. For long-reach applications, signal distortion impacts clock recovery and the fidelity of the information being transferred. This white paper looks at how to handle these issues and ensure data is successfully transmitted with low BER.

This eGuide guide shows you how to make accurate power rail measurements and how impedance measurements can help to detect typical root causes of power integrity issues.

This application note provides an introduction to the DDR memory technology and explains common challenges, related to the specific nature of DDR data, command / address and control buses and describes the typical measurements to verify and debug DDR system designs.

Compliance testing is essential to ensuring that dynamic random access memory (DRAM) signals meet the JEDEC specifications for parameters such as timing, slew rates and voltage levels.

Timing components such as low jitter oscillators and clocks are necessary to facilitate increasing data rates in high speed digital designs.

EMI radiation and crosstalk caused by poor shielding can lead to signal quality and performance degradation in electronic RF devices. To minimize the overall EMI of electronic devices, local radiation sources on the integrated boards and modules must be well known.

To investigate the stability of a switched-mode power supply, a Bode plot created with an oscilloscope is ideal for checking the critical phase margin and gain margin values. The factors that determine how satisfactory the results from Bode plot measurements will be, need to taken into consideration as part of the preparation.
