This white paper shows how the introduction of complicated figures of merit like SNDR, COM, and ERL, plus FEC (forward error correction) changes how we think about SERDES performance. SERDES tests require more than pristine signal generation and error counting. This paper presents the key SERDES tests, the need for FEC test patterns and the ability to insert errors that can probe Reed-Solomon FEC, and techniques for calibrating interference and jitter tolerance tests.
Creating a robust RF test plan for tactical and other mission critical radio systems requires specialized techniques. The standard RF channel modeling used in typical cellular and wi-fi tests can fall short. Mission critical devices encounter higher doppler, lower frequency ranges, multiple device-to-device paths and other challenges that make standard channel models and test approaches unsuitable. This webinar will examine the unique aspects of tactical and other mission critical mesh radio systems and their impacts on propagation. It will conclude with guidance in creating a robust test methodology that systematically covers conditions that are difficult to validate in the field.
Are you interested in modelling piezoelectric sensors and actuators? If so, then join us for this webinar.
In this webinar, James Ransley from Veryst Engineering will work through a case study in which the properties of a piezoelectric bender actuator are optimized. The material orientation and dimensions are optimized to maximize the efficiency of the bender for the application. The blocking curve is computed and the dimensions are modified to achieve a given specification with minimal actuator volume.
The study will also include a live demo of piezoelectric device design using the COMSOL Multiphysics® simulation software. A Q&A session will conclude the webinar.
Optimal crystal orientation and displacement profile (color is proportional to relative displacement) for a piezoelectric bender made from lithium niobate (left) and PZT 5H (right).
Application development in the mmWave frequencies for terrestrial communication, high-frequency device characterization, automotive radar and other technologies is increasing. As these applications climb from tens of GHz to over 100 GHz, the challenge of testing and characterizing the devices that enable new solutions is becoming increasingly complex. As broadband testing over hundreds of GHz of bandwidth is subject to repeatability and accuracy deficits, researchers and engineers are demanding better broadband solutions that help to overcome these challenges and simplify mmWave testing.
Defenders need meaningful situational awareness to safeguard their sensitive data and sustain key operations. By establishing visibility and accountability in Amazon Web Services (AWS), organizations gain situational awareness to detect and discern unusual events in their environment. These insights gains help security operations and defenders make informed decisions on how to respond to and recover from security events.
Attend this webinar to learn how you can systematically and methodically improve your situational awareness. Discover ways to then act upon those insights by leveraging technologies to support threat intelligence, log collection and analysis, incident response, and security orchestration.

Test engineers spend as much as 50 percent of their time (or even more in some cases) actively dealing with obsolescence in their test program sets. Read about different solutions in the marketplace to help you overcome the challenges you face today while reducing the risk of a complete technology refresh.
Aerospace and defense companies are longtime innovators and technology leaders, so digital transformation should be easy, right? Wrong. Only three percent of these projects succeed. This infographic explains what’s really happening.
Crosstalk occurs when energy radiated by an aggressor channel is absorbed by a victim channel. The amplitude of the resulting crosstalk noise is inversely proportional to the rise/fall time of the aggressor but can be reduced by channel layout. This whitepaper provides an S-parameter description of crosstalk and then works through the details of crosstalk figures of merit for differential high-speed serial systems from 1 Gb/s all the way to 112 Gb/s (56 Gbaud PAM4).
Don’t give up on digital transformation projects that have not delivered as expected. The root cause of failure often lies in data preparation. This tech brief explains how to find out what went wrong and how to get it right the next time.
