Meet Willie Washington,the beloved Washington Laboratories Test Robot at the 2012 IEEE Symposium.

This video is about Willie Runs

Willie Goes Rogue! Episode II of THE LAB

In the first episode we meet our newest engineer. Could he be Nikolai Tesla, reincarnated


Steve Ferguson discusses CS115

Steve Ferguson discusses CS116

Steve Ferguson gives the whys and hows of MIL-STD Conducted Emissions Testing. Conducted emissions testing is required to quantify unwanted noise and interference on power mains and buses. To properly measure and manage these emissions, it is necessary to understand the test setups, calibration and data collection.

CS101 is the MIL-STD-461 method of determining the susceptibility of electronic systems to low frequency conducted energy. An calibrated signal is injected into the mains of the equipment and the performance monitored. Steve Ferguson demonstrates the setup, calibration and performance of this test.

Steve Ferguson discusses CS115 and CS116.

Welcome to Espresso Classics! In this Classic we wind the clock back a bit and feature Dr. Norm Violette giving the timeless overview of EMC Concepts. If you weren’t clear on how many ways you can polish a decibel, or if memory is a sepia-hued, this short will put a little shine on this topic. Thanks, Norm!

EMC Demonstrations and Solutions: The Whys and Hows. These instructional videos show basic concepts of EMC topics such as Cable Radiation, Aperture Radiation, Magnetic Field Shielding and Conducted Emission Measurements. Watch Dr. Norman Violette, founder of Washington Laboratories Inc., as he gives a demonstration of EMC measurement and troubleshooting techniques. Practical solutions to common EMI problems provided by the accomplished and renown Dr. Violette.



Mike Violette, Steve Koster and John Repella of Washington Labs delve into the decibel. The dB is the currency of EMC and Radio Frequency engineering. Understanding how the dB is dealt with and used is a critical part of understanding, and speaking, EMC.

Our engineering classes teach us about the ideal behavior of circuit elements: wire, resistors, capacitors, inductors, etc. When used in the real world, the classic models break down. The behavior of these parts in circuits and systems may be greatly different than the designer may have envisioned. This is due to the fact that at radio frequencies, components behave according to the reactance of parasitic properties (wiring inductance and space capacitance). Steve Koster and James Ritter discuss the implications of this physical behavior and provide a demonstration of the performance several common devices using a network analyzer to evaluate the impedance of the device as a function of frequency.
