3D Radiated Spurious Emission Test System

With the rapid advent of the wireless technologies, wideband high frequency wireless systems are becoming more popular. These products bring a new challenge to the EMC compliance testing, especially for the radiated spurious emission test. The traditional 2D test method of the spurious emission is no longer suitable for these high frequency technologies certification test. A new radiated spurious emission test system is being studied in this paper, which is more suitable for the higher directive radiated emission measurements. The use of this test method can substantially reduce the measurement uncertainty.
