Near-Field
Noise Suppression Sheet Evaluation System
Intra/Inter - Decoupling Ratio(Rda･Rde) Measurement System
IEC standard No. : IEC62333-1, IEC62333-2
Model No. NSS02
There are some evaluation methods for measuring the noise suppression performance between transmission lines and circuit boards;
- Intra-decoupling ratio measurement system [Rda / Intra Decoupling Ratio]
Measurement object is placed parallel to the measurement system
- Inter-decoupling ratio measurement system [Rde / Inter Decoupling Ratio]
Measurement object crosses the measurement system
Intra Decoupling Ratio[Rda], measured by System 1, indicates the amount of how much coupling within the same board is attenuated when the EMI noise suppression sheet is attached
Inter Decoupling Ratio[Rde], measured by System 2, indicates the amount of how much the coupling between two printed circuit boards and parts is attenuated when the EMI noise suppression sheet is attached.
The systems are effective device in the development of EMI noise sheets and noise countermeasures during product development, such as digital devices and equipment.
