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. Devices may include multiple transmitters that a few years ago did not include communications of any sort. Inclusion of RF transmitters has prompted a … [Read more...]
Review of MIL-STD-461 CS103 Intermodulation, CS104 Rejection of Undesired Signals and CS105 Cross-Modulation
Introduction Rapid technology advances in the wireless communications world make test and evaluation of Radio Frequency (RF) devices a difficult subject. It seems that by the time a new device hits the market, it has been made obsolete by the next generation. I recall hearing from a major electronics manufacturer CEO that 90% of sales happen within 90-days of market release … [Read more...]
