TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • How To Perform A Radiated Emissions Measurement

    Explore the intricacies of setting up radiated emissions testing with this guide, covering everything from antenna placement and polarization to accurate frequency selection and signal measurement.

  • Accurate Test Fixture Characterization And De-Embedding

    This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND.

  • R&S®FSWP And The Validity Of Positive Phase Noise Values

    This white paper reviews the classical spectrum analyzer measurement of L(f) and its shortcomings. It also discusses how modern phase noise test sets measure phase noise and avoid the limitations imposed by direct spectrum measurements, especially with the use of the R&S®FSWP.

  • Design Of A Complete RF Downconverter Module For Test Equipment

     The example module and its constituent parts were designed and simulated with AWR Design Environment software using circuit- and system-level analyses. The integration of the downconverter within a mechanical outline influences the layout of the individual radio blocks.

  • RF Test Setup For Measuring Power & Harmonics

    Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

TEST & MEASUREMENT SOLUTIONS

The dB-3906 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3906 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

Pentek offers the Talon® RTX 2684 as a 26 GHz sentinel intelligent signal scanner recording system. The system provides SIGINT engineers the ability to scan the RF spectrum from 1 GHz to 26 GHz for signals of interest and monitor or record bandwidths up to 500 MHz wide.

Electrostatic discharge testing is utilized worldwide by electronics manufacturers to determine the ESD susceptibility of their devices. It is extremely difficult to estimate the exact cost of ESD loss annually, but it can safely be stated that ESD requires the development and testing of many hardware prototypes and contributes to a high number of warranty claims and loss of consumer confidence if failure occurs in the hands of the customer. Given the high cost in time and materials associated with ESD hardware testing, the ability to simulate the ESD testing process in XFdtd is extremely valuable, allowing engineers to pinpoint locations susceptible to ESD damage and optimize ESD mitigation during the concept and design stage of product development.

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.

Qorvo introduces the QPC2040 single-pole, double-throw (SPDT) switch operating within the 8 – 12 GHz frequency range for commercial and military radar, communications, electronic warfare, test instrumentation, and other general purpose applications. The switch typically supports 10 W input power handling at control voltages of 0/−2 V for both CW and pulsed RF operations.

The Microwave VME/VXS Tuner by Hunter Technology is the industry’s smallest available microwave SIGINT VME tuner. It covers the 500 MHz-20.0 GHz and 30.0 GHz to 40.0 GHz frequency ranges and features incredibly fast tuning, low phase noise, excellent mechanical conductivity, a single slot 6U VME configuration, and much more.

The RFvision-3 is a tunable ultra-wideband spectrum processing solution designed for 1 GHz bandwidth RF spectrum recording with advanced pulse processing. This rack-mount (3U) system is based on the DTA-9590W ultra-wideband tuner and DTA-5000 RAID server with 24 TB SSDs. It operates from 500 MHz to 18 GHz (expandable up to 40 GHz) and features 100 MHz instantaneous bandwidth.
