name: MBW
full_form: Measurement bandwidth defined for the protected band
context: is to capture the overall reflections from the chamber walls experienced by the BS/calibration antenna. To capture the full effect of the QZ ripple a distance of 1Î» should be measured from each of the BS/calibration antenna physical aperture edges, i.e. total QZ distance = physical aperture length +2 Î», to ensure the full volume of the QZ is captured in the uncertainty measurement. NOTE 3: This MU contributor is defined for normal test conditions. MU contributor for the quality of QZ in extreme test conditions is defined in A2-13. A2-5 Mismatch of receiver chain (i.e. between receiving antenna and measurement receiver (a) / low power receiver (b)) This uncertainty is the residual uncertainty contribution coming from multiple reflections between the receiving antenna and the test receiver equipment. This value can be captured through measurement by measuring the S11 towards the receive antenna and also towards the test receiver. The mismatch between the antenna reflection and the
description: The Measurement bandwidth defined for the protected band (MBW) is a parameter used in the context of RF requirements and testing procedures. It refers to the aggregated channel bandwidth located at the middle of the supported frequency range in each operating band, specifically denoted as MBW Channel CA (middle). This parameter is crucial in defining the test conditions for contiguous spectrum operation.
explanation: MBW is classified as a Parameter because it is defined within the context of RF requirements and testing procedures. The description highlights its role in specifying the aggregated channel bandwidth at the middle of the supported frequency range, which is essential for conducting tests according to the definitions provided in single-RAT specifications.
