Although all serial data standards specify a required receiver jitter tolerance, compliance testing of the link physical layer has generally ignored the receiver. This seminar fills knowledge gaps by explaining receiver testing and the complicated "recipe" of jitter sources, showing how jitter sources relate to interference mechanisms in the real communication channel, how to properly calibrate the jitter sources to assure accurate testing, and more.

Pre-emphasis and equalization are increasingly popular solutions to signal integrity problems caused by lossy backplane channels at high signaling rates, for example in Backplane Ethernet 10GBASE-KR. We show how pre-emphasis and equalization can be used to counteract channel loss. We examine how pre-emphasis affects test and measurement with examples from popular standards and look at some practical examples of pre-emphasis and equalization filters across a high speed backplane.

High-level design tools offer field-programmable gate array (FPGA) technology to engineers and scientists who have little or no digital hardware design expertise. Whether you use graphical programming, C, or VHDL, the synthesis process is quite complex and can leave you wondering how FPGAs really work. What actually happens inside the chip to make programs execute within configurable blocks of silicon? This white paper is intended for the nondigital designer who wants to understand the fundamental parts of an FPGA and how it all works "under the hood." This information, also helpful when using high-level design tools, hopefully can shed some light on the inner workings of an extraordinary technology.

As the industrial landscape continues to move toward a more automated environment, engineers implementing monitoring and control applications encounter increasingly complex systems. Such industrial control systems often consist of independent Programmable Automation Controllers (PACs) managing specific, individual tasks. As these distributed systems increase in complexity, the control and monitoring tasks must be divided among several such PACs, networked together. Ensuring proper operation of this distributed industrial process requires the direction of system managers and operators. Yet while a central control "hub" is appropriate for managerial supervision, the distributed system is incomplete without Human Machine Interfaces (HMIs) for more direct interaction. The LabVIEW Touch Panel module completes the National Instruments offering for managing remote systems by extending the LabVIEW graphical programming environment to rugged HMI industrial computers. This application note discusses the benefits of the LabVIEW Touch Panel module and provides a detailed step-by-step tutorial for adding an HMI to your existing PAC system.

This paper discusses the top ten things that you should consider if you are considering a new digitizer/oscilloscope.

Evaluating Oscilloscopes for Best Signal Visibility 

This application note reviews some of the factors that impact oscilloscope update rates and shows you how to compute probabilities of capturing infrequent events. Plus, it includes side-by-side measurement examples that compare the probabilities of capturing an anomalous event using various vendors' MSOs. Click here to download this application note.
