In this paper we'll see how PAM4 challenges signal integrity, test, and design engineers who are responsible for SERDES (serializer/deserializer) components, interconnects, backplanes, cables, connectors, circuits, and complete systems. The problems solved by PAM4 outweigh the problems it introduces. This paper will help you understand how to use S-parameters, how to think of channel response and crosstalk in terms of S-parameters, and where to look for problems that might be caused by inaccurate measurements of S-parameters.

Spectrum analyzers are the fundamental instrument used by RF engineers to measure individual signals across a defined frequency band. They capture and display wanted and unwanted signals, enabling a range of measurements including power, frequency, modulation and distortion. There are several different types of spectrum analyzer system architectures. This paper reviews the architecture of real-time spectrum analyzers (RTSA), swept-tuned spectrum analyzers, and vector signal analyzers, and highlights their relative merits and compromises.

This paper explains the relationship between noise, sampling rates, and bit depth in a system designed for IQ capture. With an understanding of these interdependencies, it is possible to optimize the configuration of a receiver, such as the Anritsu Field Master Pro MS2090A, when capturing IQ data to minimize the memory size of the resulting data file. Smaller files are typically easier to analyze in post processing tools making the identification of all signals faster and easier. P/N: 11410-02837

The superposition technique relies on the inherent linear nature of a transmission line, and mathematically derives the differential and common-mode transmission line characteristics through superposition while stimulating just one side of the balanced transmission line at a time. The true-balanced/differential technique, also known as True-Mode Stimulus, uses two sources to create actual differential and common-mode stimuli. This white paper offers guidance to signal integrity designers on the differences between these approaches and which one may best fit their need. P/N: 11410-00659

De-embedding methods making significant structural assumptions have become popular in recent years, particularly in PC board and cable assembly spaces, because of the relative immunity to repeatability and standards availability problems at the DUT plane. Some of the same issues occur in mm- wave fixtures where repeatability can be even more of a challenge. This white paper goes through the methods and behaviors of these challenges. P/N: 11410-01080
