  3. 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.

  4. Calibration-Free Return Loss Measurement 7/20/2022

    Return loss in a wired or wireless transmitter is the ratio of transmitted power to reflected power when power is being delivered to a load. It is a critical parameter that describes transmission efficiency and can be used as an indicator that excessive power is being reflected from a load back to the source. In a wireless transmitter with poor antenna return loss, a high level of reflected power can damage the power amplifier that is driving the antenna.

  5. A Measurement Summary Of Distributed Direct Sampling S-Band Receivers For Phased Arrays 6/17/2022

    This piece details performance measurements vs. predictions of a 16-channel S-band direct sampling receiver design. The design is based on recently released direct sampling analog-to-digital converters (ADCs) clocked at 4 GSPS and sampling in the second Nyquist zone of the converter. 

  6. Hybrid Beamforming Receiver Dynamic Range Theory To Practice 6/17/2022

    A commercially available 32-channel development platform is used to validate the analysis with measurements. This article covers the following comparison of measurements and analysis for receiver dynamic range metrics in a phased array hybrid beamforming architecture.

  7. 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.

  8. What Is Real-time Power Processing & Its Impact on RF Power Measurement? 5/4/2022

    Boonton Real-time Power ProcessingTM (RTPP) is a digital signal processing methodology that says goodbye to convention and hello to signal acquisition free of any gaps or latency. Let's take a look at the limitations of traditional signal processing and how RTPP paves an improved path for RF power measurements.

  9. How Can Additive White Gaussian Noise Make Directed Energy Weapons More Powerful? 5/4/2022

    An enemy target is in sight. With its location confirmed, an extremely powerful and highly focused electromagnetic energy beam (e.g., a high-power laser) is emitted to incapacitate or destroy the adversarial force. This is the mission objective of directed energy weapons (DEW).

  10. What's The Key To Quantifying A Phase Noise Analyzer's True Noise Floor? 5/4/2022

    The way most modern cross-correlation phase noise analyzers determine this figure is by approximating its value. Calculation of the noise floor approximation occurs during data acquisition of a device under test (DUT), which helps estimate the measurement margins. No matter the manufacturer, the measurement noise floor is unique for every analyzer.
