Versatile Software Tool for Rohde & Schwarz Instruments RSCommander 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.
This application note outlines two different approaches for remote-controlling Rohde & Schwarz instruments out of MathWorks MATLAB: The first one uses VISA connection and direct SCPI commands. The second approach takes advantage of Rohde & Schwarz VXI plug&play instrument drivers and MATLAB Instrument Control Toolbox.
3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 14 added several tests, especially for enhanced License Assisted Accsess (eLAA).This application note describes how all required transmitter (Tx) tests (TS36.141 Chapter 6) can be performed quickly and easily by using signal and spectrum analyzers from Rohde & Schwarz. A few tests additionally require signal generators from Rohde & Schwarz.Examples illustrate the manual operation. A free software program enables and demonstrates remote operation.The LTE base station receiver (Rx) tests (TS36.141 Chapter 7) are described in Application Note 1MA195.The LTE base station performance (Px) tests (TS36.141 Chapter 8) are described in Application Note 1MA162.
Noise Power Ratio (NPR) is an add-on tool for WinIQSIM™ to generate noise power ratio stimulus signals and measure the resulting noise power ratio of a device under test (DUT) using Rohde & Schwarz instruments via LAN or GPIB bus.
A Test Port Adapter System is implemented for all Rohde & Schwarz equipment, which operates above 26 GHz in order to protect the RF front-end from mechanical damage. The Test Port Adapter System consists of an RF front-end interface called the Test Port Adapter Body, and the Test Port Adapter Head which is attached to the Body. The Head provides an interface to a cable or device under test. This Application Note identifies the various types of Test Port Adapters, their parameters, compatibilities and usages.
This Application Note describes testing S-parameters under pulsed conditions with the R&S®ZVA vector network analyzer and either the ZVAX24 Extension unit with pulse modular option or the R&S®SMF signal generator with pulse modulator as a signal source.In addition a constant power level calibration for applications requiring high drive power for test and measurement of device under test (DUT) is also included. A LDMOS S-band radar power transistor is used as example DUT. The pulse profile mode of the R&S®ZVA is used to analyze the time-dependent behavior of the DUT.
The aim of this application note is to provide information regarding Rohde & Schwarz instrument drivers. This paper shall help application engineers and software developers to easily get an understanding of advanced techniques to develop test and measurement (T&M) applications by utilizing Rohde & Schwarz instrument drivers. Furthermore the nomenclature used for Rohde & Schwarz instrument drivers will be explained.
The use of Rohde & Schwarz device drivers under VEE software is not complicated. However, a number of factors are involved, the errors that occur are often difficult to diagnose. This application provides easy and detailed support for installation and troubleshooting using National Instruments or Agilent GPIB boards.
Most of the tests specified in the standard TIA-98 that a CDMA2000® mobile station has to fulfill can be performed by the Universal Radio Communication Tester R&S®CMU200 without further assistance. Other tests, however, require additional instruments, for instance for generating interfering signals. Some tests of the standard TIA-98 need features that a tester optimized for production cannot offer, for example high dynamic spectrum analysis up to 12.75 GHz. This Application Note shows how to perform these tests easily with the remote-control software CMUgo, using the R&S®CMU200 in combination with R&S®SMU, R&S®SMJ, R&S®SMIQ, or R&S®SML signal generators, and R&S®FSQ, R&S®FSU, R&S®FSP, or R&S®FSL spectrum analyzers. New test items and sequences will therefore be included in the CMUgo software v1.9.8 to remote-control the R&S®CMU200, as well as the signal generators and spectrum analyzers. They are presented in this Application Note.

GDE (= Generic Demonstration Engine) is a easy-to-use, free-of-charge remote control command sequencer tool. The big advantage is that the test description is stored in a simple, easy-to-read text file, and loaded in GDE at runtime. This makes it very easy to modify tests by the user or add additional tests to already existing test solutions without redistributing big setup files.
