  1. Simplify FiRa™ Certification For Your UWB Device 7/25/2022

    Seamless interoperability of UWB devices is of utmost importance for the success of UWB applications such as keyless entry, asset finding, sensing and navigation. It is essential to ensure a safe and effective user experience. The certification program established by the FiRa™ Consortium builds the cornerstone to drive interoperability across the industry.

  2. Scenario Based Testing Of C-V2X 7/25/2022

    With this process, Rohde & Schwarz creates and simulates detailed traffic situations for the verification of cellular V2X (C-V2X) connectivity.

  3. Testing Insertion Loss Of PCB Signal Structures With Delta-L 4.0 7/20/2022

    Delta‑L is an algorithm easily removes effects and calculating the insertion loss per inch of a PCB trace from measurements of test coupons with different lengths. The Delta‑L measurement workflow is fully integrated in the R&S®ZNA, R&S®ZNB, R&S®ZNBT and R&S®ZND vector network analyzers as the R&S®ZNx-K231 option.

  4. Easy Testing Of Interferometric Direction Finders 7/20/2022

    The R&S®RF Ports Alignment Software together with the R&S®SMW-K545 option provides a standard and tailored solution for calibrating and aligning the amplitude, group delay and phase between the RF ports of multiple coupled dual-path or single-path R&S®SMW200A vector signal generators. 

  5. On-Walfer Qualification Of RF Components 7/20/2022

    Characterizing a DUT at the wafer level requires a measurement system including a vector network analyzer (VNA), a probe station, cables/adapters and wafer probes. Rohde & Schwarz is collaborating with FormFactor to address wafer-level testing.

  6. Linearization Of RF Amplifiers 7/5/2022

    This white paper focuses on linearization of a non-linear device, in our case the RF power amplifier. It is shown how simulation and the integrated functions of the Rohde & Schwarz instruments R&S®SMW200A and R&S®FSW work hand-in-hand with the simulation capabilities from MathWorks in MATLAB / Simulink.

  7. 5G NR V2X For Enhanced Automotive Communications 6/28/2022

    As a humorous introduction, Rohde & Schwarz was motivated to write this white paper because vehicles are turning into “smartphones on wheels”, especially when considering the massive proliferation of wireless communications in automotive applications.

  8. Two-Port Residual Noise Measurements 6/2/2022

    Radar systems engineers were once happy simply to detect targets but, today, the target's extremely small return signal must also be extracted from high amplitude ground or sea clutter. Radar system phase noise is the key parameter defining a radar's ability to extract small signals from a noisy background.

  9. Modulation Measurement Optimizer 5/20/2022

    This document describes the approach of a waveform specific, on-site characterization of the analyzer. For each waveform and frequency of interest, the instrument is evaluated in a first step. With this additional data, a fast and repeatable auto-levelling can be performed during the actual measurement.

  10. Signal Source Level Calibration Using The FSMR3000 5/20/2022

    The R&S FSMR3000 is a three-in-one instrument incorporating a measurement receiver, a spectrum and signal analyzer, and a phase noise analyzer. This application note demonstrates the use of the measurement receiver to calibrate the signal output level of a signal generator.
