Electronically Scanned Arrays for Fast Testing of Large Antennas

February 12, 2012
This paper discuss the adaptation of the fast multi-probe technology to an existing classical planar near field facility through the manufacturing, installation and test of a partial demonstrator in Thales Alenia in Toulouse.

Leveraging OFDMA Technology for HLS Applications

February 12, 2012
In this paper we take a closer look at various OFDMA based Broadband Wireless Access (BWA) for Homeland Security (HLS) applications and their implementation. Our primary focus is to understand the capabilities required from these applications and to show how flexibility and controllability of system components can help address these requirements.

Measuring Leakage Current in RF Power Transistors

February 12, 2012
The published specifications for leakage current in RF power devices are often a source of concern and confusion for engineers and technicians. This paper examines the real meaning behind the leakage current specifications and offers guidance on properly testing a device for leakage current.

Noise Figure Measurement without a Noise Source on a Vector Network Analyzer

January 17, 2012
This application note describes the noise figure measurement using the R&S Vector Network Analyzers of the ZVA and ZVT series. It explains the concept of measuring noise figure without the need for a characterized noise source. Furthermore, it discusses different measurement applications and the respective setup and implications. Some examples guide through the instrument setups and show measurement results as well.

3GPP FDD and LTE Multicell and Multi-UE Scenarios with the R&S SMU200A Signal Generator

January 17, 2012
This application note describes how to set up 3GPP FDD and LTE multicell and multi-UE scenarios with the R&S®SMU200A with a focus on routing and leveling of the baseband signals. Furthermore, it describes in detail how to determine the correct AWGN settings, i.e. how to calculate the required signal-to-noise ratio for the various scenarios.

TETRA Measurements

January 17, 2012
TETRA, the TErrestrial Trunked RAdio, is the professional mobile radio standard (PMR) used world wide by governmental safety and security authorities and organizations, as well as by private utilities from energy suppliers through to transport. Rohde & Schwarz provide test instruments idealy suited for both the development and production of TETRA base stations and user equipment, as well as for network planning, network coverage and quality of service, network monitoring and optimization, maintenance, and service. This Application Note shows examples for measurements with R&S instruments covering the entire range of TETRA test requirements.

The Effective Number of Bits (ENOB) of my R&S Digital Oscilloscope

January 17, 2012
The effective number of bits (ENOB) is a way of quantifying the quality of an analog to digital conversion. A higher ENOB means that voltage levels recorded in an analog to digital conversion are more accurate. In an oscilloscope the ENOB is not just determined by the quality of the analog to digital converter but by the instrument as a whole. This application note explains how to measure the oscilloscope ENOB and shows results for the R&SâRTO for different settings.
