Anritsu Company Introduces WCDMA/HSDPA Modulation Quality Measurements for its High Performance Signal Analyzer

-Option Gives Digital Mobile Radio Base Station Developers a Comprehensive, Easy-to-Use Solution for WCDMA/HSDPA RF and Modulation Quality Measurements-

Anritsu Company introduces a WCDMA/HSDPA Modulation Quality Measurements option for its MS2781A Signature™ High Performance Signal Analyzer. When the option is combined with Signature’s high-performance signal analysis capability, the result is a comprehensive suite of measurements for developers of WCDMA/HSDPA base stations, and related sub-systems (e.g., power amplifiers) at both the development and production stages. Signature is part of Anritsu’s portfolio of test solutions for digital mobile communications.

Version 3.0 for Signature
The new option is part of the latest 3.0 version software enhancements to the groundbreaking Signature signal analyzer that has redefined the high-end signal analyzer market. Its advanced receiver architecture provides exceptional performance over the 100 Hz to 8 GHz frequency range. Amplitude accuracy is better than 0.65 dB, intermodulation distortion (TOI) +27 dBm, and Displayed Average Noise Level (DANL) is better than -157 dBm with 0.1 Hz BW. Demodulation bandwidth of up to 50 MHz supports capture and analysis of wideband digital modulation.

Modulation Measurements
With the WCDMA/HSDPA option installed, Signature supports a comprehensive set of measurements specified by the Third-Generation Partnership Project (3GPP). For a complete list of WCDMA/HSDPA measurements, please refer to Table 1.

Ease of Use
Signature’s Windows XP user interface makes it much easier to test the complex WCDMA/HSDPA technology and reduces mistakes. For example, familiar dialogs simplify measurement selection, and menus are optimized for touch screen operation with single-click activation. A rich set of graph capabilities supports quick viewing of results. The intuitive “Graph Type” dialog allows multiple measurement windows, for full analysis of measured data.

MATLAB Compatibility
Signature’s open Microsoft Windows® environment provides unmatched ease-of-use and supports a seamless interface to MATLAB® from The MathWorks. Designers of software defined radios (SDRs) or radios with new or unique modulation techniques can view live measurement results, post-processed by MATLAB.

The MS2781A Option 30, WCDMA/HSDPA Modulation Quality Measurements is available in 8 to 10 weeks ARO.
