  • Remote Setup for 3G High Dynamic Multi Charrier Signals with SMIQ03HD and FSU / FSQ

    Testing multi carrier power amplifiers of the 3rd Generation requires test signals with a high dynamic range. This application note describes how a 4 carrier 3G WCDMA signal can be generated and measured with the application software SET_MC4. The software sets up to 4 SMIQ03HDs to generate the signal, and an FSU or FSQ to immediately evaluate and analyze the Adjacent Channel Leakage Ratio (ACLR) of the power amplifier. The setups are controlled remotely. The SET_MC4 source code is also included. Modify the code to meet your individual requirements or adopt the IEEE-commands into your own setup script.

  • CDMA2000® Base Station Tests With the R&S®SMU200A Vector Signal Generator and Rohde & Schwarz Spectrum Analyzers

    This Application Note describes measurements compliant with the CDMA2000® base station standard described in 3GPP2 C.S0010-C v2.0 / TIA/EIA-97-F-1. The primary focus is on solutions for generating and analyzing CDMA2000® signals. The special characteristics that make the selected signal generators and signal analyzers highly suitable for this purpose are detailed, and remote control programming is demonstrated by means of a free-of-charge program.

  • CDMA2000®1xRTT / 1xEV-DO Measurement of time relationship between CDMA RF signal and PP2S clock

    This application explains the setup and procedure to measure the exact time relationship between the CDMA RF signal and even-second clock. The accurate knowledge of this time relationship is e.g. necessary for test setups which require the synchronization of the R&S®CMU200’s CDMA2000® system with a GPS simulator.

  • 802.11 Packet Error Rate Testing

    When measuring the performance of 802.11 wireless LAN compatible receivers, Packet Error Rate (PER) tests are the method of choice today. This application note describes a simple way to conduct PER tests using signal generators on any 802.11 device, independent of their physical layer design (11b, 11a or 11g). The application software works with standard Windows™ drivers on any card independent of manufacturer. No additional hardware specific software is needed. Easy setup of the source signal is included with direct upload to an SMIQ or AMIQ.

  • Generating and Analyzing CDMA2000® Signals

    This application note describes measurements compliant with the cdma2000® standard described in TIA/EIA-97-C and TIA/EIA-98-C. The primary focus is on solutions for generating and analyzing cdma2000® signals with equipment from Rohde & Schwarz. The special characteristics that make the signal generators and signal analyzers eminently suitable for this purpose are detailed.

  • Tests on CDMA2000®1xEV-DO Access Terminals in Accordance to IS-866-A

    The Universal Radio Communication Tester R&S®CMU200 can perform most of the CDMA2000®1xEV-DO access terminal (AT) tests specified in the standard IS-866-A on its own. Some tests require additional instruments. 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®AMU, R&S®SMJ or R&S®SML signal generators, and R&S®FSQ, R&S®FSU, R&S®FSP, R&S®FSL or R&S®FSMR spectrum analyzers.

  • CDMA2000®1xEV-DO Rel. B Non-Signaling Testing

    This R&S®CMU200 1xEV-DO Release B non-signaling testing application provides the means to allow users to perform RF measurements on a 1xEV-DO Rel. B access terminal in a mode that does not require any signaling. This allows the calibration and final tests of a Rel. B AT, according to the minimum performance standards with the R&S®CMU200.

  • DFS Analysis Tool, Dynamic Frequency Selection in the 5 GHz Band

    This application note describes DFS measurements with a spectrum analyzer. An external program, the DFS Analysis Tool, is used to improve measurement speed.

  • CDMA2000®1xRTT/1xEV-DO Hybrid Mode Testing

    This application note is intended as a guide to configuring the R&S®CMU200 instrument for CDMA2000®1xEV-DO / 1xRTT Hybrid Mode testing.

  • Simplify your envelope tracking system

    The R&S®SMW200A vector signal generator combined with the R&S®FSW signal and spectrum analyzer offers fast and simple power amplifier testing including envelope tracking and digital predistortion, effectively replacing complex test setups.
