The indoor antenna range consists of a Scientific-Atlanta #4139 Positioner Controller for positioning the AUT and Tx; an Orbit/FR #442 simultaneous motion power control unit (3- axis controller, AUT azimuth and polarization, Tx-Polarization); an Agilent E8634A PNA series network analyzer (45MHz-50GHz) for RF measurements and data acquisition; and a Dell dimension system controller running the antenna measurement software. Fig. 2 shows part of the antenna range.
