Passive and active antenna testing from 400MHz to 6GHz. Passive antenna testing provides information regarding: antenna pattern, antenna gain, antenna efficiency and antenna correlation. Active antenna testing provides information regarding device sensitivity (TIS) and the device's radiated power (TRS). All antenna testing is peformed in CTIA-approved fully anechoic chambers to ensure that only signals to and from the device are measured. To measure each point, the positioning system moves the DUT (Device Under Test) relative to the measurement antenna.
