full_form: Equipment Under Test (UE or UE with ancillaries)
context: The reference angular steps and in degrees are defined as: The upper limit for these reference angular steps of ensures a low Summation Error (SE) when is large compared to the EUT dimensions. Dcyl and D are calculated as: The definition of d, w and h is shown in figure G.2.2-1. The radiation source can be EUT antenna array or the whole of EUT. Figure G.2.2-1: Dimensions of a radiation source: depth (d), width (w) and height (h) Optionally, in the case of Uniform Linear Array (ULA), when d is negligible (d ) and the EUT is mounted along the yz plane as shown in figure G.2.2-2, the reference angular steps, in degrees, can be determined by Where Dy is the length of radiating parts of EUT along y-axis, Dz is the length of radiating parts of EUT along the z-axis and is wavelength for the measured frequency. Figure G.2.2-2: Spherical coordinate for OTA conformance testing of EUT Where due to practical reasons such as time constraints or turn-table precision, measurement with the reference
description: The Equipment Under Test (EUT) is a device undergoing testing to evaluate its performance and adherence to established standards. It can encompass either a User Equipment (UE) or a UE augmented with ancillaries, which are additional devices connected to the network.
explanation: The text explicitly states that EUT is a device being tested for its characteristics and performance in relation to the network, aligning it with the definition of a Device.
