N2 - The three-dimensional (3D) sectored multi-probe anechoic chamber (MPAC) configuration has been seen as a promising solution of over-the-air (OTA) testing of large array systems. The prefaded signal synthesis (PFS) channel emulation method emerged to be better than the plane wave synthesis (PWS) channel emulation method for 3D sectored MPAC system. Yet, the PWS has been proven to be more accurate than the PFS for 2D MPAC. To explain these seemingly contradicting findings, these two channel emulation methods are investigated in this paper. It is found that the PWS method exhibits better performance than PFS method only when the number of active probes becomes sufficiently large, whereas the PFS is more robust to the undersampling due to limited active probes in practical 3D sectored MPAC system.
