各位:
在测试三相电能表的CE项目时,得到如下结果:QP值刚好不超限值线,而AV值却超了限值线,请问该产品是否合格?
准峰值测量结果: Frequency (MHz) | QuasiPeak (dBμV) | Line | Margin (dB) | Limit (dBμV) | 0.154000 | 63.0 | N | 2.8 | 65.8 | 0.205000 | 59.0 | L1 | 4.4 | 63.4 | 0.257000 | 58.5 | L1 | 3.1 | 61.5 | 0.365000 | 58.5 | L3 | 0.2 | 58.6 | 0.413000 | 57.2 | L1 | 0.4 | 57.6 | 0.469000 | 52.0 | L1 | 4.5 | 56.5 |
