  • Characterization of Satellite Frequency Up-Converters
    Characterization of Satellite Frequency Up-Converters

    This application note describes methods using an R&S®ZVA network analyzer, one or two R&S®SMB100A signal generators and an R&S®FSW signal analyzer to accurately measure all the key parameters of frequency converters with embedded local oscillator. A commercial satellite up-converter is used as a device under test example.

  • Automated Measurements of 77 GHz FMCW Radar Signals
    Automated Measurements of 77 GHz FMCW Radar Signals

    This application note focuses on fully automated, fast and accurate measurements, of linear FMCW radar signals. It explains the basic signal processing, the impact on radar key performance indicators in case of linearity deviations and explains test and measurement of linear FMCW signals in detail.

  • Voice Over LTE (VoLTE) Speech Quality Measurements
    Voice Over LTE (VoLTE) Speech Quality Measurements

    This Rohde & Schwarz application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively. The R&S CMWrun Software Sequencer Tool example sequences perform decoder / encoder calibration, connection setup for the UE under test and subsequent speech quality analysis under IP impairment conditions.

  • Measuring Channel Operating Margin
    Measuring Channel Operating Margin

    Channel Operating Margin, COM, is a single measure of channel performance with high data rates that includes the effects of signal impairments and the techniques used to compensate for those impairments. COM measures the performance margin of an interconnect, and can also be used to examine the interoperability margin of a high speed serial system. The derivation of COM itself can offer insights into the strengths and weaknesses of a design due to the inclusion of the ISI (inter-symbol interference) calculation that remains after equalization and the effects of noise, jitter, and crosstalk.

  • How To Measure Additive Phase Noise Of Amplifiers Using 7000 Series Signal Source Analyzers

    The 7000 series phase noise measurement system is designed to measure absolute and residual (additive) phase noise of active or passive devices. This app note explains how to use 7000 series signal source analyzers to measure the absolute or residual phase noise of pulsed signals in amplifiers.
