电冰箱的CE测试,不光是0.74M超标,奇怪的是平均值大得离谱,居然超过了准峰值。
但CISPR14-1里说
If the limit for the measurement with the average detector is met when using a receiver with a quasi-peak
detector, the equipment under test shall be deemed to meet both limits and the measurement using the receiver
with an average detector need not be carried out.
这不是说明了准峰值总是大于平均值的,只要准峰值满足了平均值的限值,就认为平均值也满足限值,无需测试。 |
