the georgia tech research institute has implemented a new 10*12 foot, planar near field range which is based on an accurate mechanical scanner. the system includes provision for active probe position correction to maintain planarity to +or-0.002 inches. the rf instrumentation is based on the hewlett packard 9510b network analyzer which provides a good combination of measurement accuracy, speed, and dynamic range. probe position is driven by micro-stepper motors under pc control. in the near future, control of the positioner, rf instrumentation, and graphics output will be under the control of a single pc-based 386 cpu system. experience gained with this new range will assist in advancing practical applications for near field testing, such as on-site testing using a portable facility
