TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• How To Configure Generic Devices In R&S Elektra

  R&S ELEKTRA is able to communicate with many devices. Still, it is impossible to integrate drivers for all devices. Hence, R&S ELEKTRA offers the possibility to integrate any device by configuring a generic driver.

• Power Supply Control Loop Response Measurements (Bode Plot)

  The R&S^® RTx-K36 frequency response analysis (Bode plot) option provides a low-cost alternative to low frequency network analyzers or dedicated standalone frequency analyzers. 

• DPX® Acquisition Technology For Spectrum Analyzers Fundamentals

  Signal detection is the first step in characterizing, diagnosing, understanding, and resolving any problem that relates to time-variant signals. Engineers are requiring better tools to help find and interpret complex signal behaviors and interactions. The Tektronix Digital Phosphor technology, or DPX®, can be used in Real-Time Spectrum Analyzers (RSAs) to reveal signal details that are completely missed by conventional spectrum analyzers and vector signal analyzers. This white paper describes the methods behind the DPX Live RF spectrum display, swept DPX, Time-Domain DPX Displays, DPX Density™ measurements, DPX Density™ and Frequency Edge triggers.

• 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.

• 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.
