Improved techniques for the measurement of radiated emissions inside a screened room

A Standard source method for reducing antenna factor errors in shielded room measurements

“…The appeal of shielded room measurements is a combination of economics, inertia (they have been used for decades), problems or limitations in other techniques, and the fact that performance/procurement standards such as MILSTD 461/462 specify using shielded rooms [8,9] [3,10], electrically small probes [10,1 1], alternative procedures for specific situations [12,13], development of numerical and circuit modeling tools to help explain measurement results [14][15][16], the use of electromagnetic absorbing material to reduce room reflections [1 1, 17,18], and development of antenna-shielded room calibration procedures [19][20][21].…”
