ANRITSU has released a WCDMA/HSDPA Modulation Quality Measurement option for its MS2781A Signature High Performance Vector Signal Analyser.

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 (such as 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 analyser that has redefined the high-end signal analyser market.

Its advanced receiver architecture provides exceptional performance over the 100Hz to 8GHz frequency range.

Amplitude accuracy is better than 0.65dB, intermodulation distortion (TOI) +27dBm and Displayed Average Noise Level (DANL) is better than 157dBm with 0.1Hz BW.

Demodulation bandwidth of up to 50MHz 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 3GPP.

Signature's Windows XP user interface makes it much easier to test the complex WCDMA/HSDPA technology and reduces mistakes.

For example, familiar dialogues simplify measurement selection and menus are optimised for touch screen operation with single-click activation. A rich set of graph capabilities supports quick viewing of results.

The intuitive 'Graph Type' dialogue 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, which can view live measurement results, post-processed by MATLAB.
