SETUP
The distance between the faces of the Transmit and Receive antenna arrays is adjusted as specified for each test. The azimuth of the Receive antenna array relative to the Transmit antenna array is adjusted as specified for each test. Azimuth is defined as the angle between the line that connects the center of the face of the Transmit antenna array and the center of the face of the Receive antenna array, relative to the vector normal to and centered upon the Transmit antenna array. Left and Right Azimuth are defined relative to this normal vector, as seen from behind the Transmit antenna array.

7. MEASUREMENT PROCEDURES The energy pockets are formed at the receiver locations. The receiver antenna arrays deliver DC power to the electronic load which measures received power. The load is s/w controlled to measure voltage and current, and calculates the power delivered. Measurements are made at each position.

7. MEASUREMENT PROCEDURES The energy pockets are formed at the receiver locations. The receiver antenna arrays deliver DC power to the electronic load which measures received power. The load is s/w controlled to measure voltage and current, and calculates the power delivered. Measurements are made at each position.
