As Over The Air (OTA) measurements become more important in 5G technologies, Anritsu proposes a new measurement method for solving millimeter-wave OTA measurements that solves the current Far-Field Measurement (FFM) challenges, and helps to reduce measurement costs. Based on actual measurement results, Anritsu's Near-Field Measurement (NFM) method is capable of offering improved measurement sensitivity. Anritsu also introduces an NFM solution for the E-band using Non-Linear Transmission Line technology. This white paper discusses how Near-Field Measurement technology works, the advantages of using it, and comparisons between NFM and FFM measurement results.
Bulk current injection (BCI) testing is a conducted susceptibility procedure that uses an injection current probe. This paper provides an example of BCI testing, covering all steps, including gathering the required equipment, pre-calibration procedures, injection testing procedures, and safety precautions.
Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This article provides a brief summary of the transmission modes in LTE and describes the beamforming measurements for base stations and user equipment.
This application note provides information on the testing of a Buck-type DC/DC subsystem that uses switch mode power supply technology and the oscilloscopes used to conduct the test.
