I don't know how you could get a uniform field one meter deep three meters from a transmit antenna. The only way I know to get a deep field for testing purposes is using a parallel plate, and that has bandwidth and polarization limitations. My understanding of the 1000-4-3 calibration is that the quiet zone is a vertical 1.5 m square plane, located three meters from the transmit antenna.
