UMTS/W-CDMA Design

To deliver the services and system improvements promised by W-CDMA, the RF performance of Basestations (BTS) and User Equipment (UE) has dramatically increased. Bandwidths are wider, modulation schemes are complicated and signals are much more dynamic in nature. These technology changes have created much more complicated, integrated devices, thus making the task of characterizing and troubleshooting a design more challenging than ever before. The Tektronix RSA3408B and WCA200A Series of Real-Time Spectrum Analyzers offer unique multi-domain views of W-CDMA signals that provide powerful insights into the complex relationships between the time, frequency and modulation domains.

Application Information

  • Characterization of IQ Modulators Counts On Flexible Signal Generator Stimulus
    This application note describes several of the important measurements design engineers routinely make on an IQ modulator. It illustrates how modern arbitrary/function generators provide a stimulus to characterize high performance IQ modulators thoroughly, with more flexibility and saving considerable time over previously used methods.
  • WiMAX Analysis Software Solution for Real-Time Spectrum Analyzers
    This fact sheet gives a brief look at how RSA-IQWIMAX software on the Real-Time Spectrum Analyzer provides spectrum and modulation measurements on OFDM and OFDMA signals in accordance with standard IEEE 802.16-2004 (fixed) and IEEE 802.16e (mobile) WiMAX standards.
  • RSAVu Remote Control Demos
    This reference guide describes how to communicate remotely with RSAVu and the Real Time Spectrum Analyzer (RTSA) via SCPI commands by the use of two examples, one in C++ and one in MATLAB
  • RSAVu Offline Analysis Software for RSA6000 and RSA3000 Series
    RSAVu software enables offline demodulation and analysis of data captured from Tektronix Real-Time Spectrum Analyzers (RTSA). From 3G wireless standards to the latest RFID formats, RSAVu is a tool designers can use to analyze signals without having RTSA hardware connected.
