  • RSCommander

    Versatile Software Tool for Rohde & Schwarz InstrumentsRSCommander is a versatile software tool for a wide range of Rohde & Schwarz spectrum-, network analyzers, signal generators and oscilloscopes. It allows for automatic instrument discovery, making screenshots, reading traces, file transfer and simple script creation.

  • OTA Link Budget Calculator

    The document gives an overview and user guide about a link budget calculator for the main components of a basic OTA system. The calculator shall guide the user to plan link budgets, especially with respect to SNR requirements for the receive components and the vector signal analyzer. An Excel sheet containing the Link Budget Calculator accompanies the application note.

  • R&S®FSQ-K70 Vektorsignalanalysator - Specifications

    English (PD 0758.1706.22)

  • R&S®GSASLP Satellite Link Planner R&S®GSACSM Communication System Monitoring
  • Remote Monitoring and Control of the R&S®FSL with a Web Browser

    This application notes describes remote operation or monitoring of the spectrum analyzers R&S® FSL3, R&S® FSL6, R&S® FSL18 through a standard web browser. The common cross-platform technology Virtual Network Computing (VNC) is used as a server on the instrument.

  • Group Delay and Phase Measurement on Frequency Converters

    Frequency converters e.g. in satellite transponders need to be characterized not only in terms of amplitude transmission but also in terms of phase transmission or group delay, especially with the transition to digital modulation schemes. They often do not provide access to the internal local oscillators This application note describes a method using the R&S ZVA to measure group delay of mixers and frequency converters with an embedded local oscillator very accurately. The key aspect of this new technique is, that the network analyzer applies a 2-tone signal to the frequency converter. By measuring the phase differences between the two signals at the input and at the output, it calculates group delay and relative phase between output and input.

  • Using the R&S®FSW for Efficient Measurements on Multi- Standard Radio Base Stations

    This application notes introduces the Multi-Standard Radio Analyzer function of the R&S®FSW and shows how it performs the measurement on multi-standard radio transmitters. It reveals interactions caused by the coexistence of signals of different cellular standards and localizes the root cause. With an example of a base station signal consisting of three radio access technologies (GSM/WCDMA/LTE FDD) it shows how easy interactions can be found. The R&S®FSW is the ideal tool for trouble shooting tasks with its combination of a large bandwidth and the versatile Multi-Standard Radio Analyzer in one measurement instrument.

  • Ground Station Testing On Satellites In Orbit

    After a communications satellite is on its target orbit, several routines need to be performed in order to ensure proper performance from the transponders in the payload. The on-orbit measurements are a vital part of the maintenance of a live satellite as well. Operating a satellite channel for an on-orbit measurement rather than the intended application comes with significant opportunity cost and hence test duration needs to be minimized as much as possible.Rohde & Schwarz test and measurement equipment recommended in this paper is market leading not only in terms of measurement accuracy but also offers unparalleled speed of measurement.This application note focuses on satellite post-launch or on-orbit measurement and monitoring strategies used for satellite functionality checks when running maintenance routines. A complementary paper treats pre-launch payload measurements.

  • Multi-TS Streaming Software

    The R&S®TSStream multi-TS streaming software streams a number of MPEG transport stream files simultaneously over a single IP interface. The individual transport streams result in a high overall bit rate. To make the streams available on a standard PC, the R&S®TSStream software does not play the transport stream files directly from the hard disk but first loads them into the RAM. The maximum number and length of the transport streams depends solely on the PC's available RAM.

  • Smart solution for satellite level monitoring

    Smart solution for satellite level monitoringEIRP measurements in the receive path of satellite links present a special challenge for T&M equipment in commercial satellite communications – and a new field of applications for the R&S® NRP-Zxx series of power sensors. The sensors measure EIRP at the detached antenna system of a Eutelsat earth station – with high accuracy and speed and excellent
