“…Field scanners are often used for the characterization and calibration of measurement environments. In AC, they can be used, e.g., for the investigation of unwanted reflections [8], for the characterization of TZ quality and calibration of the individual PWG channels [9], and for the evaluation and optimization of the TZ in CATR systems [10]. In RCs, field scanners can be used to experimentally estimate the planewave spectrum under different loading conditions [11].…”

This paper investigates the characterization and calibration procedure of the hybrid over-the-air (OTA) measurement chamber. We present a prototype of the hybrid chamber and analyze its capabilities to generate a plane wave spectrum in practice. A planar field scanner is used to acquire the embedded element fields of the chamber array for test zone (TZ) synthesis in post-processing. The repeatability of the field acquisition is evaluated. It is shown that the synthesized TZ meets the 3GPP specifications for TZ field variations for plane wave generators (PWG) in the presence of acquisition imperfections.

“…While we describe our overview of the experimental setup and conclude with results of reflectivity levels captured for both vertical and horizontal polarizations. For Fourier analysis based offline processing of sampled vector-data, we refer to [27,120,121]…”

“…Although the FSVSWR test yields the chamber reflectivity, there are limitations to the technique, and the results vary based on the probe antenna used [124]. In addition to the FSVSWR test, another technique for chamber characterization is based on Fourier analysis [121,120] that has since been adopted in the next revision of the IEEE 149 standard. The Fourier analysis approach is more intuitive as it provides hotspot locations of the reflections in addition to the reflectivity levels of the chamber.…”
