Anritsu Company Introduces First Signal Analyzer Integrating Fixed and Mobile WiMAX Measurement Capability

June 13, 2006

Anritsu Company introduces the MS2781B Signature High Performance Signal Analyzer, which is the first signal analyzer to integrate a full suite of physical layer measurements of both fixed and mobile WiMAX signals. The MS2781B also delivers industry-best spectrum analyzer measurement performance and speed for accurate analysis of advanced RF signals used in wireless communication networks.

Equipped with the WiMAX option, the MS2781B can display a variety of measurements, including a constellation of a mobile WiMAX signal with 64QAM, 16QAM, and QPSK formats simultaneously, as well as BPSK pilots. The analyzer’s residual Error Vector Magnitude (EVM) for WiMAX signals is 0.5% (-46 dB). Its demodulation bandwidth of up to 50 MHz supports capture and analysis of wideband digital modulation, including all WiMAX-specified bandwidths.

The MS2781B provides unprecedented spectrum analyzer performance as well as digital modulation analysis over the 100 Hz to 8 GHz frequency range. It delivers an unprecedented DANL (Displayed Average Noise Level) of -167 dBm without a preamplifier, as well as TOI (Third Order Intercept) of +22 dBm. The result is the best dynamic range of any signal analyzer on the market. Such performance is achieved due to the MS2781B’s fundamental mixing approach that allows the entire frequency range to be measured in one sweep, without bandswitching or preselection.

Open Windows® Environment

Anritsu has designed the MS2781B with an open Windows environment that makes it easy to integrate popular simulation and analysis tools. For example, the Windows environment allows the MS2781B to have a seamless interface with MATLAB®. This allows designers of software defined radios (SDRs) or radios with new or unique modulation techniques to view live measurement results, post-processed by MATLAB, directly on the MS2781B’s display.
