TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Four Practical Applications Using An Electronic Load

  This article presents four tips on how to test with electronic loads and illustrate the flexibility and usefulness of a DC electronic load. 

• Noise Figure: What Is It And Why Does It Matter?

  Noise figure is a key parameter that quantifies receiver performance by measuring how low a power a signal receiver can detect. This white paper covers the basic principles of noise figure, how to make sense of its specifications, how it is measured, and why this parameter is important in high-performance applications.

• 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.

• 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.

• De-Embedding Test Fixtures For High-Speed Digital Applications

  Test fixtures are commonly used in high-speed digital measurement to connect devices to measurement equipment. Characterization and analysis in time and frequency domains help remove the influence of these fixtures.
