Applications & White Papers for CDMA2000®EV-DO

  • 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.

  • 1xEvolution – Data Optimized (1xEV-DO)is a 3GPP2 “cdma2000® High Rate PacketData Air Interface” specification. Since its introduction (Release 0), Revisions A and B have brought improvements in the data throughput in both directions and in the overall network capacity. This white paper presents the Revision A and B concepts for 1xEV-DO and explains key features.

  • Integrated end-to-end data solution with IP traffic analysis and protocol statistics allows detailed analysis of data traffic generated by IoT and mobile devices.

  • 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.

  • This white paper describes the POLQA® algorithm implemented in the R&S®UPV Audio Analyzer and shows an example hardware setup for standard independent audio measurements.

  • This Application Note describes measurements compliant with the cdma2000® base station standard described in 3GPP2 C.S0010 / TIA/EIA-97 / ARIB STD-T64-C.S0010.
    The primary focus is on solutions for generating and analyzing cdma2000® signals. The special characteristics that make the selected signal generators and signal analyzers eminently suitable for this purpose are detailed, and remote control programming is demonstrated by a free of charge program.

  • 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.

  • Recent mobile test methods could not evaluate the quality of data reduced speech signals with different coded and decoded signals. The Perceptual Evaluation of Speech Quality (PESQ) provides the solution for this measuring problem. CDMA2000® PESQ is an add-on tool for CMUgo for automatic measurement of the PESQ for CDMA2000® mobile phones according to recommendation ITU-T P.862.1 featuring selectable fading profiles and variable Additional White Gaussian Noise (AWGN).

  • 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.

  • 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.

  • This application note provides a summary of the current test solutions available with Rohde & Schwarz equipment. The opportunities provided by the individual devices are presented briefly and a demonstration using a spectrum analyzer and a vector signal generator is described.

  • 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.

  • 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.

  • As well as static tests, modern mobile communication standards also stipulate measurements under fading conditions, sometimes with additional white gaussian noise AWGN. Rohde & Schwarz supports these tests with the combination of the R&S®CMU200 Radio Communication Tester and the R&S®SMU200A or R&S®AMU200A Vector / Baseband Signal Generator and Fading Simulator. Applying fading and noise always raises the crest factor of a signal considerably. Thus, automatic path attenuation inside the Rohde & Schwarz baseband fader prevents the new signal peaks from being clipped at I/Q full scale. Any additional attenuation in the baseband, however, makes the RF output fall below its intended level. This application note shows how to achieve an accurate RF output level by compensating for the I/Q attenuation - without modifying the test setup or using additional instruments.

  • 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.

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

  • The Rohde & Schwarz R&S®CMU200 can be configured to perform packet data testing in a Mobile IP or Simple IP environment. This application note is intended as a guide to configuring the necessary Mobile IP or Simple IP network elements and R&S®CMU200 instrument for CDMA2000®1xEV-DO.

  • The Rohde & Schwarz R&S CMU200 can be configured to perform packet data testing in a Mobile IP or Simple IP environment.
    This application note is intended as a guide to configuring the necessary Mobile IP or Simple IP network elements and R&S CMU200 instrument.

  • This application note describes how to generate cdma2000® signals for wide ranging receiver tests under fading conditions for cdma2000® 450/Cellular/PCS/IMT-2000 mobile and base station equipment. The test setup requires an Rohde & Schwarz Universal Radio Communication Tester CMU with IQ-IF interface option CMU-B17 and a baseband fading simulator ABFS. The cdma2kFadLevCor program included with this application note performs a semi automatic level correction of the power fed to the Device Under Test (DUT).

  • The R&S®CMU200 provides the signals required for 2nd order intermodulation (IM2) performance verification for WCDMA / CDMA2000® chipsets with zero IF design.
    This application note is a guide to configure the R&S®CMU200 for such an application.

  • The SMIQB60 option is an internal two channel arbitrary waveform generator based on the modulation coder SMIQB20. SMIQB60 uses an innovative interpolation filter technique to increase memory capacity.
    Waveforms can be calculated and transmitted with the external PC-Software WinIQSIM™ and stored in the non volatile memory of SMIQ. Stored waveforms can be recalled by SMIQ without using WinIQSIM™.
    The cal_iqskew software can calibrate the SMIQB60 outputs for an improved dynamic range. Please read section 6 of the Application Note for more information before you use the software.

  • In combination with the R&S®FSH handheld spectrum analyzer, the R&S®EX-IQ-Box digital signal interface module significantly simplifies RRH installation and inspection in distributed network architectures.
