CISPR 16-1-1 Ed.3 published
CISPR 16-1-1 Ed.3, Specification for radio disturbance and immunity measuring apparatus and methods - Part 1-1: Radio disturbance and immunity measuring apparatus - Measuring apparatus, was published by the International Electrotechnical Commission on January 28, 2010. Edition 3 lets you use a spectrum analyzer at frequencies below 1 GHz, provided that it has the proper average and quasi-peak detector (down to 20 Hz) and meets all other stated requirements. CISPR standard up for a vote explains the rationale behind Ed. 3.
Mart Coenen commented:
I dear to say that there is still no common sense when using a spectrum analyzer for EMI measurements. Rather than focussing on the detector, overloading of the input will be more crucial when using a spectrum analyzer over an EMI receiver. Still, when one does not want to go for peanuts, when the product measured with a spectrum analyzer (when demonstrated that it is not overloaded)indicates that the product fulfils the QP requirements while using the standard (SA) peak detector, there is nothing to worry about and there is a 100% guarantee that the product will fulfil the requirements when formally tested.
