TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

Application Note: Reflectometer Measurements - Revisited Twenty four years ago Wiltron (now Anritsu) published a Technical Review "Why Tolerate Unnecessary Measurement Errors", long since out of print...
Using FEKO To Calculate Radar Cross Section Of Aircrafts With Engine Inlets
Asymptotic methods are the preferred method for calculating the radar cross section (RCS) of targets like aircrafts since the main parts of the target are more than an order of magnitude larger than the wavelength.
Application Note: Mixer VNA Measurements By Anritsu Company Frequency-translated devices are key components of any communication system, whether they are up-converters, down-converters, or basic mixers. Since their input and output frequencies are different, they require special features and setups for vector network analyzer (VNA) measurements. With the frequency offset capability of today's VNAs, where the source and receiver are independently synthesized, such measurements are possible and require a much less complicated setup.
Optimize Beamforming: From Bits To RF Beams
To achieve accurate, reliable and efficient beamforming, it is necessary to understand and compensate for the nonlinear behavior of RF components. This app note covers the benefits of Rohde & Schwarz’s portfolio of conducted and OTA test solutions and how they help to optimize beamforming.
Measuring Channel Operating Margin
Channel Operating Margin, COM, is a single measure of channel performance with high data rates that includes the effects of signal impairments and the techniques used to compensate for those impairments. COM measures the performance margin of an interconnect, and can also be used to examine the interoperability margin of a high speed serial system. The derivation of COM itself can offer insights into the strengths and weaknesses of a design due to the inclusion of the ISI (inter-symbol interference) calculation that remains after equalization and the effects of noise, jitter, and crosstalk.

TEST & MEASUREMENT SOLUTIONS

Vector Network Analyzers: MS4640B Series

Anritsu offers the ability make VNA measurements of devices under test (DUTs) stimulated with wideband modulated signals. Utilizing the high speed IF digitizer option available in the VectorStar® series of VNAs, measurements can be made with up to 200 MHz of instantaneous bandwidth in the receiver. Universal Fixture Extraction (UFX) software option provides advanced de-embedding tools for test fixture extraction.

Antenna Test System: R&S®ATS1000

The R&S®ATS1000 antenna test chamber is designed to provide the ideal environment for 5G antenna characterization throughout the entire process from R&D to production for both active and passive devices. This system supports far-field and near-field antenna measurements with its compact design. The mobile chamber helps to optimize the overall RF performance of antenna modules already in the initial phases of development.

K Band Motion Sensor Modules: SSM Series

These motion sensor modules are short range Doppler sensors that operate in the K band. They’re ideal for traffic radar systems, automatic door openers, dual mode security systems, and automatic production lines.

Real-Time Spectrum Analyzer: RSA5000 Series

Rigol offers the RSA5000 Series Real-Time Spectrum Analyzer delivering class leading 7.45 µsec 100% probability of intercept, meaning that any pulse with duration greater than 7.45 µsec will be captured and accurately displayed. This device includes advanced trigger capabilities, making the task of identifying and isolating signals of interest easier.

High-Definition Video Clock Generator

The VFCG-HD1 is a fully integrated video clock generator which provides synchronous High Definition (HD) and Standard Definition (SD) output clocks for the various scanning formats. The device synchronizes to the standard input reference clock required by SMPTE274, SMPTE296, NTSC, or PAL systems.

Surface Mount Mixer And Detector Schottky Diodes: SMS7630 Series

The SMS7630 Series comprises low-cost, surface mountable, plastic packaged silicon mixer Schottky diodes designed for RF and microwave mixers and detectors. They include low barrier diodes and zero-bias detectors that combine Skyworks advanced semiconductor technology with low-cost packaging techniques. All diodes are 100 percent DC tested and deliver tight parameter distribution, which minimizes performance variability.

High Power Microwave Signal Generator: Model 845-HP

Higher power in their signal generators was Berkeley Nucelonics’ number one request from their customers, and they delivered on it. The model 845-HP microwave signal generator is very similar to the model 845, but its wide and accurately levelled output power range (up to +23 DBM) and high spurious suppression set it apart.

2-18 GHz Broadband Synthesizer: BXFS1045

The BXFS1045 is a fully customizable broadband synthesizer covering the 2 to 18 GHz frequency range. It’s ideal for applications involving microwave receivers, microwave telemetry systems, uplink communications platforms, instrumentation, and communications systems, and is well suited for both military and commercial applications.
