Session 1: An Insider’s View on the Changes to MIL-STD 461G and 464 Work Items
MIL-STD-461G was released to the public in December of 2015 with sweeping changes to the EMC test standard. This briefing is more than a simple laundry list arrived at by performing a side-by-side “F” vs. “G” comparison. Instead, it is an insider account into the issues with which the Tri-Service Working Group (TSWG) was grappling, and the thought processes behind the changes, as well as, of course, the changes themselves. It also lists some of the issues brought to the table that were not incorporated in MIL-STD-461G, and why. Also discussed are the updates and proposed work items for the upcoming revisions to MIL-STD- 464C.
Session 2: Capturing Pulsed/Intermittent Signals: A Study of Test Methodologies
Pulsed and/or intermittent signals are difficult to detect and even more difficult to properly characterize the amplitude across frequencies. There are several methods to perform the task and a thorough understanding of the method of measurements for each is necessary to assess the strengths and weaknesses. Three EMC test methodologies are studied: Frequency Swept, Frequency Stepped and Time Domain Scan. We will demonstrate the details of each for a pulsed signal stimulus and provide insight for best measurement techniques for each method.
Session 3: Debugging EMI Problems Using an Oscilloscope and Near-Field Probes
Electromagnetic interference is increasingly becoming a problem in complex systems that must interoperate in both high speed digital and RF domains. When failures due to EMI occur it is often difficult to track down the sources of such failures using standard test receivers and spectrum analyzers. This course will present a method of evaluating EMI in real time using a near field probe and a digital oscilloscope. We will look at techniques to capture transient events in the time and frequency domains that reveal details about the sources of EMI that can quickly lead to mitigation strategies.
Session 4: Verifying MIL-STD-461G CS101 Using Frequency Domain Measurements on a Digital Oscilloscope
MIL-STD-461G defines the EMI and EMC requirements for military vehicles and aircraft. This presentation will focus on the measurement verification challenges defined by the standards and provide insight into new verification techniques for the test methods of CS117 and CS119.
