@tabbott,Mike M非常感谢!
我今天做了新测量,看起来更像是合规性测量。
我还有一个问题:我在哪里可以找到使用哪种平均值检测器(平均值,RMS平均值,EMI平均值),当我想根据EN55015进行测量时,我使用哪一种?
野兽的本质是EMI探测器扫描速度慢...... EN 55015指定的平均探测器就是安捷伦所称的* EMI平均值*探测器。
我们的频谱分析仪多年来都有一个*平均值*探测器,多年来它们在不同的平均类型上都有一些增强。
但是,由于某些商业EMC标准要求的平均探测器与我们的频谱分析仪所具有的平均探测器有很大不同,我们需要通过给它一个稍微不同的名称来区分它,因此我们将其称为* EMI平均值*。
这是您需要用于这些标准的检测器。
EMC接收器中的* RMS Average *检测器是几年前添加到CISPR 16-1-1标准中的。
在这个时间点,世界各地的管理机构使用非常有限。
如果您对加速测量感兴趣,请使用峰值检测器进行扫描,并仅使用EMI平均值检测器(或您需要使用的任何EMC检测器)检测感兴趣的信号 - 接近极限的信号。
(信号列表和测量序列对此有利,因为标记功能单独测量)这是一种可接受的方式,因为任何信号的EMI平均值检测器值都不会大于峰值检测器测量的值。
最好的问候,迈克

The nature of the beast is that EMI detectors are slow for scanning...
The average detector that EN 55015 specifies is what Agilent calls the *EMI Average* detector. Our spectrum analyzers have had an *Average* detector in them for many years, and they have had some enhancements over the years with different average types. But since the average detector that certain commercial EMC standards require is much different than the average detectors that our spectrum analyzers have had we needed to differentiate it by giving it a slightly different name, so we call it *EMI Average*. This is the detector that you need to use for these standards.
The *RMS Average* detector in an EMC receiver is something that was added to the CISPR 16-1-1 standard a few years ago. At this point in time this has very limited use by the governing bodies around the world.
If you are interested in speeding up your measurements use the peak detector for doing your scans and only use the EMI Average detector (or whatever EMC detector you need to use) for signals of interest - ones that come close to your limit. (The signal list and measure sequence is good for this, as is the Measure at Marker function by itself) This is an accepted way of doing this since the EMI Average detector values for any signal will never be greater than measured by the peak detector.
Best regards,
Mike
