The Huntsville Chapter of the IEEE Electromagnetic Compatibility (EMC) Society invites you to attend a IEEE EMC Distinguished Lecturer Meeting on September 18, 2014 featuring a talk given by Professor James Drewniak.  The program will begin at 5:30 pm with Gary Ziadeh of Amplifier Research sponsoring a free catered meal.  Professor Drewniak’s technical presentation will begin at approximately 6:15 pm after some short chapter status updates.

Synopsis:

Managing intentional currents and anticipating un-intentional currents for EMI design
The signals and logic levels in analog and digital electronics are based on voltages, and a typical university education in circuits, electronics, and digital design is very on voltage-centric. However, the parasitics that limit the performance of a design in practical applications are most easily understood, characterized, and an equivalent circuit model and topology developed from an understanding of the specific signal current path. Similarly for un-intentional current paths that comprise the EMI coupling path and lead to radiation provide a systematic approach for understanding, diagnosing, and mitigating EMI problems. This presentation will detail a methodical approach for identifying current paths – intentional and un-intentional – and detail a means of developing equivalent circuit models for parasitics in signal paths, as well as EMI coupling path models for un-intended current paths, together with example case studies.

Seating is limited to the first 50 people registered. You must Register on VTools as soon as you can, but no later than 5:00 p.m. CST September 18, 2014.

The Huntsville Chapter of the IEEE Electromagnetic Compatibility (EMC) Society invites you to attend a Technical Meeting on March 22, 2014 featuring a talk given by Tim Dew.  The program will begin at 5:30 pm with Phillip Stallcup & Nancy Richardson of Agilent Technologies sponsoring a free catered meal. Tim’s technical presentation will begin at approximately 6:20 pm after some short chapter status updates.

Synopsis:

During recent history of MIL-STD-461 testing, the 50µH LISN has ruled the general test setup. However with other EMC requirements and typical vehicle size, most tests would benefit from the use of the 5µH LISN. This is a presentation of the necessity of moving toward using the 5µH LISN for the general test setup and using the 50µH LISN for specialized cases.

The meal and presentations are open to anyone interested in EMC or Circuit Design: IEEE membership is not required to attend.

Seating is limited to the first 50 people registered. You must Register at https://meetings.vtools.ieee.org/meeting_view/list_meeting/24673 as soon as you can, but no later than 2:00 p.m. CST March 18, 2014.

The Huntsville Chapter of the IEEE Electromagnetic Compatibility (EMC) Society invites you to attend a Technical Meeting on February 27, 2014 featuring a talk given by Louis A. Feudi.  The program will begin at 5:30 pm with Teseq Inc. sponsoring a free catered meal. Louis’ technical presentation will begin at approximately 6:20 pm after some short chapter status updates.

Synopsis:

Many test labs conduct EMC Radiated Immunity Testing. Some require 3V/m, some 10V/m. Some even higher for MIL Std and DO-160 Testing. Most EMC tests require 80% amplitude modulation. HIRF requires pulsed applications.

Selecting the correct amplifier power rating can be effected by the compression point of the amplifier, the need to add 80% AM, Cable losses, Antenna Gains, and Semi Anechoic Chamber calibration ratings. This lecture reviews the operation of TWT, solid State, and Pulse amplifiers and provides guidelines for the selection of the power needed to conduct these tests within the linear amplification of the amplifier.

The meal and presentations are open to anyone interested in EMC or Circuit Design: IEEE membership is not required to attend.

Synopsis:

This presentation deals with the following cases:

Problem #1 arose when an airframer was performing low-level swept cw illumination of an aircraft in order to determine proper BCI drives on critical cables, and measured an inordinately large current value, and imposed same on avionics vendor.

Problem #2 is an observation that the technique (SAE ARP 1972, DEF-STAN 5941, RTCA/DO-160D-G, MIL-STD-461 CS114) has changed over time, and perhaps not for the better: a look at the evolution of the methodology, and why the original was closer to reality.

“Meal – Southern BBQ:”

Pulled Pork, BBQ Chicken Quarters,
Baked Beans, Corn on the Cob
Potato Salad, Buns/ Rolls, Cobbler (Blackberry)
Sweet and Unsweet Tea, and Water

Meeting Location: ADTRAN in the North
Tower, Bridge Training Room

Date: August 15, 2013

Time: 5:30 p.m.

The Huntsville chapter of the IEEE Electromagnetic Compatibility (EMC) Society invites you to attend a technical meeting on August 15, 2013.   The program will begin at 5:30 pm with Owen Wireman of Newtons 4th USA Inc. (N4L), sponsoring a free catered meal.   Tim Ardley’s talk will begin at approximately 6:20 pm after some short chapter status updates.

Synopsis:

The presentation will first look at lightning and the level of current seen during a lightning strike.  Equipment is not normally designed to withstand a direct lightning strike, but most damage is caused by surge being induced on to the AC or communication ports for example. Where the equipment is deployed will largely dictate the expected levels of surge that can be seen by the equipment.

The presentation will look at the threat levels that can be seen to help in the design.  Copper communication lines that go external to the building are often protected by a primary protector where  these are normally gas discharge tube (GDT) primary protectors that is often rated up to 20kA.  Equipment often needs to have secondary protection that will reduce the let-through of the primary protector down to ensure sensitive IC’s are not damaged.  This presentation will look at how to ensure coordination between primary and secondary protection and various coordination elements that can be considered.

Bio:

Tim Ardley is a Power Fault & Lightning Compliance Engineer at Adtran.  Previously, he was employed by Bourns Inc as the global reference design Manager and Senior telecom Field Applications Engineer.  Tim has also worked for Fairchild Semiconductor and Texas Instruments in the UK where he also earned a Bachelor of Science degree at Luton University in England.

The meeting will be held at ADTRAN in the North Tower, Bridge Training Room. The directions are included below. (follow the RED line on the map).

Synopsis:

We often hear the guideline of use three different capacitor values rather than a single value. Is this good advice? Of course the answer is, “…it depends”. In this presentation, I illustrate the analysis path we take to explore this answer.
