Jeff Viel of NTS Corp.

This one-hour session will cover basic principles for EMI/EMC testing, and the purpose of the MIL-STD-461 standard. A general overview of each test method and importance of test setup, equipment configuration and operation are discussed. This session will also highlight some of the most common product compliance issues encountered during MIL-STD-461G testing, and lend advice on how they are remedied.

Overview of RTCA DO160G-

This one-hour session will cover a general overview of each test electrical and EMI related method (sections 15 through 23 and section 25). Comparisons will be made to aircraft platform requirements defined in MIL-STD-461G test setup. This session will also highlight some of the most common product compliance issues encountered during DO160G testing, and lend advice on how they are remedied.

International standards comparison-

This one-hour session will compare and contrast the product compliance requirements across several industries in an effort to highlight changes in platform electromagnetic environments, and how these changes can lead to severe compliance risks for multifunctional products deployed across a variety of commercial and defense platforms.

Zhong Chen of ETS-Lindgren

There are some practical considerations for antennas used for EMC measurements; for example, EMC antennas are typically extremely broadband and low gain.  At below 1 GHz, these antennas are used over a perfect electrical conductor (PEC) ground plane.  This presentation provides an introduction and discussion of the antenna fundamental parameters from an application point of view, especially on how these antenna parameters are characterized and applied in EMC applications.  We will review the definition of Antenna Factor (AF), its relationship to antenna gains, and mismatch losses.  We will also look at other parameters often used in EMC applications, such as antenna balance, phase center, and site attenuation.  A brief introduction to EMC antenna calibration methods will be provided, including a reference to dipole-like antennas, which are ubiquitous for EMC measurements below 1 GHz.  Finally, we will discuss how these antenna parameters, such as the free-space antenna factors, are impacted by the presence of the conducting ground plane.
