TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • 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.

  • Linearity Of The JFET And MOSFET When In Saturation Over The Entire Cycle

    Performing RF amplification in a way that is simultaneously linear and efficient has been a challenge in power amplifier (PA) design. Single transistor PAs can either be operated in a linear, but inefficient, current source mode of operation or as efficient, but nonlinear, switches. These techniques use two FETs, but this paper demonstrates that linear amplification can be achieved at high power with an efficiency greater than 60%, using a single FET.

  • Crowdsourcing Versus Mobile Network Testing

    The need for an objective evaluation of mobile network quality and performance drives two fundamentally different approaches, crowdsourcing, and mobile network testing.

  • 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.

  • Measurement Of The Phase Between Several Signals

    Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument. 

TEST & MEASUREMENT SOLUTIONS

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 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 series of GORE® VNA microwave/RF test assemblies from W.L. Gore are designed to provide the most precise VNA measurements in laboratory conditions, setting the standard for vector network analyzers (VNAs) through 70 GHz. These test assemblies deliver the highest accuracy and greatest time intervals between recalibrations for many applications, including those with vector network analyzers, critical measurements, and laboratory testing.
