We analyze the wave propagation characteristics of the CISPR 25 radiated emission test setup with numerical simulations. Bad repetability of the standardized ALSE validation procedure urged us to develop a new, more stable procedure. Our new validation procedure uses a small conical dipole antenna instead of the test harness which improves the repeatability and avoids impedance problems of the artificial network and the noise source. Furthermore it allows precise measurements to investigate the influence of test bench dimensions and grounding. Results of these investigations are shown.
