TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

Field Probe Correction Factors
To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.
Selecting Your Next Oscilloscope: Why Digital Triggering Matters
Many people tend to overlook the importance of triggering while selecting an oscilloscope, but it's actually a crucial factor to consider. Digital triggering can offer some significant advantages.
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.
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.
