Radiated Emission Measurements at 1/3/5/10/30 Meters
Daniel Hoolihan, Hoolihan EMC Consulting, Lindstrom, MN Trend shifts towards making measurements at antenna distances closer and closer to the equipment-under-test. INTRODUCTION There are two principal types of emission measurements in the world of electromagnetic compatibility: conducted emission and radiated emission. The conducted emission measurements are either a … [Read more...]
Egregious Errors in Electromagnetic Radiation Evaluation
Reasons for widely differing results in commercial radiated emission measurements. MIL-STD-461 RADIATED EMISSION MEASUREMENTS In 1967, the first version of MIL-STD-461 was introduced. Radiated emission measurements were allowed outside of a shielded room but due to the low levels of radiated emission limits, compared to an average ambient, measurements were invariably made … [Read more...]
