What is the difference between an equivalent time and a real-time oscilloscope? - Application Note  
This document will discuss how each type of oscilloscope samples the incoming waveform and explain the trigger requirements.

Application Note 2013-11-18

Using Equalization Techniques on Your Infiniium 90000A Series Oscilloscope 
A transmitter sends a serial signal over a transmission channel (examples: backplane, cable) to a receiver. As the signal rate increases, the channel the signal travels through distorts the signal at the receiver.

Precision Waveform Analysis for High-Speed Digital Communications - Application Note 
This document will discuss the Keysight 86108A precision waveform analyzer plug-in module with the Keysight 86100C DCA-J sampling oscilloscope mainframe for accurate analysis of high-speed digital communications signals.

Application Note 2008-04-17

Precision Jitter Analysis Using the Keysight 86100C DCA-J - Application Note 
This product note provides a guide to making jitter measurements with the Keysight 86100C DCA-J.

Application Note 2007-03-07

Comparison of Different Jitter Analysis Techniques With a Precision Transmitter - Application Note 
This white paper describes how various jitter analysis techniques give dissimilar results. Which is right? We built a precision jitter transmitter to compare results of different techniques where test sets were exposed to known levels of jitter.
