Jointly presented by two extraordinary women engineers, Adriana and Maria Clara, this presentation shares some inspirational stories from their own journey of becoming engineers in Colombia. Through their eyes, we will see how two girls growing up discovered their passion in science and engineering, and how they pursued their dreams despite many challenges. They’ll share their stories of the encouragement they received along the way which guided their careers towards becoming leaders in electronics engineering and bioengineering.

This 4-day Military Standard 810 (MIL-STD 810) test training focuses on the purpose of each test, the equipment required to perform each test, and the methodology to correctly apply the specified test environments. This class is applicable to ANY testing done to Environmental test standards including DO-160, IEC specifications, and all other documents which provide test methodology for environmental testing. The test methods explained and taught in this class apply to environmental testing of ANY equipment whether it is intended for military/aerospace, commercial, or consumer use.

Vibration and Shock methods are covered together. We overview Sine and Random Vibration, also classical waveform shock testing, drop testing and Shock Response Spectrum Testing. We include instrumentation, vibration equipment, control systems and fixture design.

We discuss each climatic test individually, focusing on requirements, origination, equipment required, test methodology and understanding of results.

Class members will tour a lab that daily performs the full spectrum of 810H tests.

The lab visit will include a demonstration of the vibration test equipment and test techniques discussed in class. An instrumented resonant structure is excited first with slowly sweeping constant acceleration sine vibration. As the frequency increases the observers will see directly the decrease in displacement. The sine vibration demonstration will be followed by an all-frequencies-simultaneous random vibration. Responses are compared.

Classroom discussion is supported by projected visuals and video clips. Commencing with a review of basic vibrations, we will explore vibration measurements and analysis. We’ll compare sinusoidal vs. random vibration testing systems, specifications, standards and procedures. We will emphasize vibration and shock test fixture design, fabrication, experimental evaluation and usage. We will study shock measurement, shock response spectrum (SRS) and shock testing.

Climatic testing will be looked at in great detail, emphasizing required equipment and instrumentation, correct interpretation of specifications and hints to ensure that the tests are brought to a successful conclusion.

In addition to the detailed observations of chambers in the Lab, numerous photographs of general purpose and special purpose chambers are provided such as Solar Radiation and Rain. Along with “catalog photos” of chambers, the instructor shows unpublished factory in-construction via photos of chambers.

The course emphasizes topics you will use immediately. Suppliers to the military services protectively install commercial-off-the-shelf (COTS) equipment in our flight and land vehicles and in shipboard locations where vibration and shock can be severe. We laboratory test the protected equipment (1) to assure maximum equipment survival and possible combat, also (2) to meet commercial test standards, IEC documents, military standards such as STANAG or MIL-STD-810H, DO-160, etc. Few if any engineering schools teach about such protection or such testing. Hence this specialized course.

Comparison of 810 Revisions

810H is the latest revision. MIL-STD-810 has been revised roughly every 8 years since it was introduced in 1962. Some of the earlier revisions are occasionally cited in procurement contracts. This course covers ALL the test methods of the latest revision. The last method numbers are found in the final column of this available-for-download PDF file. The instructor will also discusses commonly specified older legacy methods.

In this session we will discuss some of the key Research, Development, Test & Evaluation (RDT&E) challenges when developing and deploying RADAR & EW systems that need to function in congested and/or contested RF environments. Topics include an overview of the issues facing coexistence, such as a contested and congested spectrum, spectral sensing and sharing, and dynamic spectrum allocation. We will highlight some real-world examples of coexistence challenges such as c-band 5G and aircraft RADAR altimeters and GPS interference with co-located satellite-based communication. This session will conclude with an overview of the characteristics and architectures of test systems that are used to create realistic RF environments to test systems under real-world operational conditions in a controlled laboratory environment.  

What you will learn:

• Common challenges when developing and deploying RADAR & EW systems
• Understanding coexistence challenges with real-world examples 
• How to create realistic RF environments to test systems in a controlled laboratory environment

Join us for a free webinar on Adding UNII-4 Band to Previous UNII Approvals. This webinar will be presented on Thursday, April 11, 2024, at 1:00 PM ET/10:00 AM PT. The presentation will be between 45 to 60 minutes, with time for questions at the end. Tim Johnson, American Certification Body (ACB) will present this informative event. If your schedule doesn’t permit you to attend the live presentation, you can still register and receive a link to the recording that will be sent out later, but you must register at least 24 hours before the event time.

The EMC Europe 2024 Symposium is poised to be a dynamic platform where leading experts, researchers, and practitioners will come together to share their latest findings, engage in vibrant discussions, and forge collaborations that will propel the field of Electromagnetic Compatibility forward. Through a carefully curated program featuring keynote speeches, technical sessions, workshops, and tutorials, we aim to explore the frontiers of EMC, covering a broad range of topics such as measurement techniques, computational electromagnetics, electromagnetic risk management, and more.
