RS(IEC61000-4-3)新法规测试疑问
新法规要求测试80M-1G,1.4G-2.7G, 其中是否有豁免频段,wifi产品,2.4G, 测试到2.4G左右时,无线会断ping,过了这个频段就恢复了,
忘记在那看见过有豁免频段,请DX们帮忙确认下,谢谢了! 标准上没有特别的豁免频段,所以你只有整改产品了。 RE有豁免频段,RS貌似没有。 WI-FI 2.4G无线产品有豁免频段,具体请参考 EN301489 无线部分的标准。上面有描述的。 ETSI 301 489上有规定的,RS肯定有豁免频段的:
The exclusion band for immunity testing shall be calculated as follows:
• lower limit of exclusion band = lowest allocated band edge frequency -5 %;
• upper limit of exclusion band = highest allocated band edge frequency +5 %.
Using the 2,450 MHz band as an example:
• lower limit of exclusion band = 2 400 - 120 = 2 280 MHz;
• upper limit of exclusion band = 2 483,5 + 124,175 = 2 607,675 MHz;
• thus the exclusion band for 2,45 GHz equipment falling within the scope of the present document extends from
2 280 MHz to 2 607,675 MHz.
