GIM01 isĀ  the 3D gimbal at the center of all MilliBox products. Wiring of the device-under-test (DUT) is done with on axis pass-through channels to prevent tangling. The DUT is mounted on the laser-guided 3D gimbal rotating platform. The 3D gimbal is controlled over a simple USB connection with software (source provided) containing all the functions and API to run and plot a full spherical (or partial) radiation pattern graph up to 1 degree resolution (64000 points). The outcome of the sweep is a comma separated value (.csv) heat-map file listing all captured positions and captured data.
