name: DUT
full_form: Device under Test
context: The DUT positioning on head phantom means that the measurements are performed so that the DUT is placed against a SAM phantom. The characteristics of the SAM phantom are specified in Annex A.1.1. The DUT is attached to the SAM phantom in âcheekâ position as defined in IEEE Std 1528. The DUT performance is measured on both left and right side of the head. The DUT positioning on laptop ground plane phantom means that a laptop ground plane phantom is used for radiated performance measurements in case of plug-in DUT like USB dongles that is used away from the userâs head. The DUT is connected to the USB connector of the laptop ground plane phantom. The characteristics of the laptop ground plane phantom and the DUT positioning are specified in Annex A.1.2. The objective of the laptop ground plane phantom is to reproduce the effects of the ground plane for the antenna of the DUT while avoiding the variation of the measurements introduced by a real laptop. The DUT shall be plugged into the
description: The Device Under Test (DUT) is the specific device being evaluated or measured in a testing scenario. This could be a smartphone, USB dongle, or any other telecommunications device subjected to tests and assessments according to telecommunications standards.
explanation: The text explicitly states that the DUT is the 'specific device being evaluated' and 'subject to various tests'. This clearly identifies it as a physical device (a type of Device) within a testing context.
