TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • On-Wafer Characterization At sub-THz Frequencies

    New technologies and applications extend into sub-THz frequencies in the D band and beyond. New semiconductor technologies and processes need to be commercialized to support these efforts.

  • Ensuring Test Site Compliance for Radiated Emissions With Normalized Site Attenuation

    This application note provides a synopsis of Normalized Site Attenuation (NSA) and Reference Site Method measurements which indicate a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR.  

  • An Introduction To Direction Finding Methodologies

    All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

  • Testing For Coexistence In Crowded And Contested RF Environments

    In this paper, we review some of the key research, development, test and evaluation (RDT&E) challenges that arise when developing and deploying systems that need to operate in congested and/or contested RF environments.

  • Radiated Wireless Coexistence Testing

    This application notegives the reader a clear idea of how to configure standardized test instruments from R&S in order to generate the wanted signal as well as unintended interference signals and conduct measurement to monitor device performance.

TEST & MEASUREMENT SOLUTIONS

The dB-3907 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-3907 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

Producing a system that excels in performance and reliability is easy when you have System Design and Applications Engineers with years of experience, Customer Service with global reach, and products that are known for performance and quality. AR has this very organization and product offerings. AR is here for you at each step to ensure that the system design, integration, and support of your EMC or RF system complies with your goals.

Microwave Systems offers the MS010620 multi-octave, high-power GaN amplifier designed to operate from 1 to 6 GHz. It is ideally suited for use in communications systems, radar systems, test instrumentation, broadband RF telemetry, point to point radio, and fiber optics applications.

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.

Holzworth’s multi-channel RF synthesizer architecture is a complete success story. These compact, 1U high, 19in rack mountable chassis can be configured with up to 8 independently tunable channels. All integrated channels are 100% phase coherent. Holzworth has designed the multi-channel platform for integration of our HSM Series Single Channel Synthesizers to maximize channel-to-channel stability via a conductively cooled, fan-less enclosure.

The EVO-RSA-6070A is part of the EVO Series of extended frequency spectrum analyzers from Avcom designed for higher performance and agility in applications with continuously changing requirements. The included SDR-style technology analyzer includes a wide bandwidth receiver and employs FPGA, DSP, and high-performance processors.

The A.H. Systems' line of Current Probe Calibration Fixtures are a great way to keep your broadband Current Probes, and Injection Current Probes calibrated and up to date. Their rugged design ensures long life, and faultless operation over the wide calibration frequency range of 10 kHz to 1000 MHz.

The Si894x is a galvanically isolated delta-sigma modulator which outputs a digital signal proportional to the voltage level at the input.
