White Papers

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.

Optimizing Your Millimeter-Wave Test Capability

January 16, 2013
Testing at millimeter-wave frequencies brings new and different measurement challenges, so minimizing measurement uncertainty is critical in the development of these new technologies. This white paper discusses the challenges associated with millimeter-wave testing and how to optimize your Vector Network Analyzer (VNA) measurement capability to provide the confidence required to make performance/cost tradeoffs.

High Voltage Inverting Charge Pump Produces Low Noise

December 15, 2012

Dual-polarity supplies are commonly needed to operate electronics such as op amps, drivers, or sensors, but there is rarely a dual-polarity supply available at the point of load. The LTC®3260 is an inverting charge pump (inductorless) DC/DC converter with dual low noise LDO regulators that can produce positive and negative supplies from a single wide input (4.5V to 32V) power source. It can switch between high efficiency Burst Mode® operation and low noise constant frequency mode, making it attractive for both portable and noise-sensitive applications.

CVD Diamond High Power Resistors and Terminations

December 15, 2012

Commonly used substrates for high power resistors and terminations are Beryllia, Aluminum Nitride, and to alesser extent, Boron Nitride and Silicon Carbide. While these materials are known for their superior thermal properties, none of them come even close to matching the thermal conductivity of CVD Diamond.
