ABSTRACT:
An automated apparatus and method which can sequentially move a RF probe through the 16 measurement positions specified in the IEC 1000-4-3 field of uniformity measurement test. The time consuming task of precisely positioning the probe, entering and exiting/opening and closing the anechoic chamber and turning the power off while repositioning the probe is eliminated. The apparatus utilizes stepping motors. The apparatus is lightweight, mechanically simple, ascetic, rugged, consistently reliable and precise, and may be easily transported and set up.
