Describes all chamber functions.

The R&S®ATS1000 is a highly accurate solution for testing 5G antennas up to millimeterwave frequencies in a mobile shielded chamber.

The R&S®ATS1000 antenna test chamber is the ideal environment for 5G antenna characterization throughout the entire process from R&D to production for both active and passive devices.

This application note describes how to measure the antenna pattern of a mm-Wave device in the R&S®ATS1000 shielded chamber. This includes the required calibration of the measurement setup and a possible near field to far field transformation when measuring larger devices.

The R&S®QuickStep ATSCAL application supports over-the-air (OTA) calibration and basic measurements in combination with the R&S®ATS family of anechoic chambers. Multiple Rohde & Schwarz RF instrument combinations and positioners are supported. A streamlined graphical user interface (GUI) simplifies parametrization and execution of the OTA calibration and measurements.

LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.This paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (OTA) measurements.

Rohde & Schwarz presents the R&S®ATS1000 antenna test system, a highly accurate solution for testing 5G antennas up to mmWave frequencies in a mobile shielded chamber.

In wireless communications, an antenna is an essential device made of conductive metal that transmits or receives electromagnetic radio waves. As the main enabler of wireless communications, antennas must satisfy a number of challenging parameters such as a wide frequency range, flat gain curves and high mechanical stability, so that they can support an ever increasing range of applications.Wireless communications testing requires over-the-air (OTA) test systems with various antenna types that serve different system functions. A variety of basic antenna designs have become established over time. These include standard gain horn, Vivaldi, patch and array antennas. Each has unique features that make them ideal for a specific application.Test antennas /probes, link/communications antennas and calibration antennas are used in OTA test systems.
