But... In addition to different spectrum analyzer configurations, the limits required are also different. So whether you meet your applicable standard can depend both on the sort of emissions you have, the test methods, and the limits.senmeis said:Hi,
I’ve read military EMC standard (such as MIL 461) requires peak detection while consumer standard requiers average detection. Does it mean the peak detection is stricter than the average one?
EMC peak and average detection are two methods used to measure electromagnetic compatibility (EMC) in electronic devices. The main difference between them is the type of signal they measure. Peak detection measures the highest amplitude of a signal, while average detection measures the average amplitude over a period of time.
Neither method is inherently more accurate than the other. The choice between peak and average detection depends on the type of signal being measured and the specific requirements of the EMC test. In some cases, peak detection may be more appropriate, while in others, average detection may be preferred.
Peak detection is useful for detecting short duration, high amplitude signals that may not be captured by average detection. It is also simpler and less computationally intensive compared to average detection, making it a faster method for measuring EMC.
Average detection is commonly used for measuring continuous signals, such as those found in power supplies or communication systems. It is also useful for measuring signals with a high level of noise, as it can provide a more stable measurement by averaging out the noise over time.
Yes, peak and average detection can be used together to provide a more comprehensive analysis of EMC. By using both methods, a more complete picture of the signal can be obtained, taking into account both the highest and average amplitudes. This can be particularly useful for complex signals or in cases where both short duration and continuous signals need to be measured.
