Comparison of configurations for conducted emission measurement specified in CISPR 32 and CISPR 13

Configurations, such as the physical layout of the measurement setup and operation conditions of equipment under test (EUT) especially the complexity of the displayed image for conducted emission measurements specified in CISPR 32[1] differ from those in CISPR 13 [2]. CISPR 32 requires a typical system configuration but CISPR 13 does not require the system. After CISPR 32 was published, multimedia equipment (MME), which has broadcast receiver functions measured with the configuration in CISPR 13 shall be measured with that in CISPR 32. Therefore, effects of differences in configurations for conducted emission measurement have to be clarified to obtain equivalent results. From the results of investigations into asymmetric mode conducted emission measurements, more practical operations of EUT can be simulated with the physical layout in CISPR 32. Also, the conducted emissions did not significantly change due to the complexity of the images displayed on the monitor.
