Review of Space Applications EMC Requirements
The Contract Having been a long-time manufacturer of oxygen concentrator equipment, when I saw an opportunity to bid on a job to provide an oxygen concentrator system (OCS) for a satellite project I jumped at the chance. The specifications were normal for this type of system and of course electromagnetic compatibility (EMC) requirements were included. Having experience with … [Read more...]
Review of MIL-STD-1399-300-1 Requirements
Introduction The electrical power system of a ship functions like a city’s electrical grid from the power generation to medium voltage distribution to the low voltage networks located in various sections of the ship’s structure. It only makes sense to treat the power system like a city’s power system, after all larger vessels include services that a city would … [Read more...]

In this review, the discussion will focus on the various requirements … [Read more...]
Review of MIL-STD-461 General Requirements
Introduction Recently I noted that my series on MIL-STD-461 test methods was closing since I had accomplished a review on each of the test methods. It seems appropriate to continue with a review of General Requirements – those things common to the various test methods. These requirements have been around since the first release of MIL-STD-461 and MIL-STD-462 dealing with … [Read more...]
Review of MIL-STD-461 CS116 Damped Sinusoidal Transients, Cables and Power Leads
Introduction In this article, I am delving into the evolvement of CS116 testing, the background, the purpose and how the testing is approached today. The test title is, “Conducted Susceptibility, Damped Sinusoidal Transients, Cables and Power Leads”. MIL-STD-461 assigns applicability to a broad variety of applications and states the purpose is to verify the ability of the … [Read more...]
Review of MIL-STD-461 RE103 Antenna Spurious and Harmonic Outputs
Introduction Technology frequently embeds transmitters in a myriad of devices to support an Internet Of Things (IoT) concept from identification to condition-based actions, and this IoT approach includes defense operations.
