White Papers

Advanced VNA Cable Measurements

April 16, 2013
This field brief will discuss phase-matching cables, S-parameter definitions as they apply to cable characterization and other cable parameters such as Phase Shift and Group Delay. Advanced Time-Domain measurements will also be presented as enhancements to the well-known Distance-to-Fault (DTF) techniques. In addition, diagnostic tools like the Smith Chart will be briefly described.

StarMIMO

April 2, 2013

The primary goal of the MIMO OTA measurement system is to be able to compare Multi-antenna/MIMO devices and algorithms based on their throughput performances when tested against spatial channel models. All critical parts of the mobile terminal design (antennas, RF front-end, baseband processing) are tested in an end-to-end configuration. This document aims to present all the most relevant technical features of the MVG StarMIMO system relative to the MIMO OTA measurement technique with anechoic chambers.

"S" Series Amplifiers Produce Higher Power, Higher Fidelity Signals For Testing Wireless Output Devices

March 20, 2013
The purpose of this application note is to review a portion of the wireless technology and focus on a line of amplifiers that has been optimized for wireless test use. This analysis can also be applicable to some additional portion of wireless technology.

Introduction to Radar System

February 16, 2013
This White Paper provides a general overview of different military and commercial radar systems. It also covers some typical measurements on such systems and their components.

T&M Solutions for software Defined Radios (SDR)

February 15, 2013
This white paper presents the basic idea behind software defined radio (SDR) and provides an overview of the Rohde & Schwarz radios and further details of SDR test and measurement solutions offered by Rohde & Schwarz.

Overview of Tests on Radar Systems and Components

February 15, 2013

The scope of the subject has expanded in the recent years in terms of its technical evolution and spreading of applications. This application note along with its corresponding white paper 1MA207 show how to use the R&S radar product portfolio to tackle test and measurement tasks in modern radar technology. Target groups are students who want to become familiar with radar issues as well as radar professionals who want to solve certain test and measurement tasks.

Increasing Power Amplifier Test Throughput

January 16, 2013
Engineers who test mobile power amplifiers and front end modules are looking for ways to reduce test cost through maximizing throughput while ensuring that the devices meet required performance levels. This application note discusses these complex issues and recommended solutions using the Agilent PXI M9381A Vector Signal Generator as an example.

Fundamentals of Arbitrary Waveform Generation, A High Performance AWG Primer

January 16, 2013
The new generation of AWGs can address a broad range of applications and test cases. This primer discusses characteristics and fundamentals of an arbitrary waveform generator and the different implementations available in the market.

Choosing the Right RF Cable Assembly

January 16, 2013

Because coaxial cable assemblies are so vital to such a wide range of systems, from rugged ground-based electronic systems to orbiting satellites in space, the selection process for those cables should not be treated lightly. Choosing the right coaxial cable assembly is not a trivial task, but it is one that can be made somewhat easier by better knowing what to look for in a high-frequency or high-speed coaxial cable assembly.

Understanding VCO Concepts

January 16, 2013
This application note looks at VCO fundamentals, for typical oscillator designs through tuning sensitivity characteristics. Examples of a Colpitts and Clapp circuit are presented.
