  1. EMC Test Chambers Case Study 1/26/2021

    Using proprietary modeling tools (numerical simulations to predict RF performance) along with Building Information Modeling (BIM) during the design phase, ETS-Lindgren optimized Alter Technology's chamber configuration not only to fit perfectly into the limited space, but also to maximize the chamber performance beyond the specified requirements.

  2. Identifying Defective Single Elements In Antenna Arrays 1/11/2021

    This white paper discusses fault identification in single elements of antenna arrays by scanning in the near-field range and applying near-field to far-field transformation methods. It also present’s Rohde & Schwarz’s solution to efficiently identify individual defective elements in magnitude and phase within an antenna array.

  3. Consider The Source: Reliable Network Analysis Starts With A Clean Signal 1/11/2021

    In wireless and satellite applications where speed, phase performance, and repeatability are critical, network analyzers with DDS sources deliver consistent results without the need for averaging. Digital-signal creation ensures low phase noise and fast frequency changes with continuous phase, reducing uncertainty in phase sensitive measurements.

  4. The Basics Of Military EMC Testing 12/22/2020

    Although the onus is not on the EMC test engineers and test laboratories to make the decisions on test levels, limits, and requirements, they are still required to identify test specifications and define test procedures, as well as perform the tests. 

  5. R&S®FSWP And The Validity Of Positive Phase Noise Values 11/19/2020

    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.

  6. How To Analyze Passive Low Frequency Components With A Rohde & Schwarz Oscilloscope 11/19/2020

    This white paper presents a technique for easily and quickly analyzing low frequency response on an oscilloscope with the R&S®RTx-K36 frequency response analysis (Bode plot) option, which uses the oscilloscope’s built-in waveform generator to create stimulus signals ranging from 10 Hz to 25 MHz.

  7. Reduce Risk With A Better Measurement Process 11/16/2020

    Measurement risk is the probability of making an incorrect decision. Many quality standards require calibration to reduce measurement risk. This white paper explores calibration, how it mitigates risk, as well as different calibration deliverables that can reduce testing costs.

  8. DPX® Acquisition Technology For Spectrum Analyzers Fundamentals 11/2/2020

    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.
