TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Combining On-Wafer VNA And Spectrum Analyzer Measurements

    This app note describes how S-parameters and spectrum analysis can be monitored simultaneously from 70 kHz to 110 GHz using the VectorStar ME7838A, the Spectrum Master MS2760A, and the Anritsu MN25110A W1 coaxial precision directional coupler.

  • 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.

  • Voltage Standing Wave Ratio (VSWR) Explained

    Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.

  • Solving Tomorrow's Obsolescence Challenges Today

    This white paper discusses best practices in operations implementation, hardware acquisition, and software design to reduce the sustainment burden of handling obsolescence in test systems long before the equipment goes end of life.

  • 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.

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.

dB Control’s family of traveling wave tube amplifiers (TWTAs) features a combined frequency range of 2 to 18 GHz up to 15kW output power. dB Control utilizes our proprietary transformer fabrication, encapsulation and high-voltage potting techniques developed for demanding military applications which results in superior reliability, low cost and ease of maintenance.  Products in this series are ideal for several applications, including: test and measurement, electronic warfare (EW) simulation, RFI/EMI/EMC Testing, electronic countermeasures (ECM), and antenna pattern and radar-cross section measurements.

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.

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.

Holzworth Instrumentation was founded as a phase noise measurement company. Along the path to phase noise analysis solutions, our high performance building blocks were developed and sold in the form of RF Synthesizers, Phase Detectors, etc. The HA7401A is a Fixed Frequency Phase Noise Analyzer, and the HA7402A is a Phase Noise Measurement Engine.

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.

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.

The GORE® PHASEFLEX® Series offers the smallest, lightest, internally ruggedized microwave/RF test assemblies for high density interconnection in RF and uW modular applications as well as in high speed digital testing. These assemblies feature ON cable construction and provide consistent, repeatable measurements with electrical performance up to 18, 26.5, 40, or 50 GHz.
