Anritsu Launches Signal Analyzer Integrating Fixed And Mobile WiMAX Capabilities
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 spectrum analyzer performance as well as digital modulation analysis over the 100 Hz to 8 GHz frequency range. It delivers a DANL (Displayed Average Noise Level) of -167 dBm without a preamplifier, as well as TOI (Third Order Intercept) of 22 dBm.
Anritsu has designed the MS2781B with an open Windows environment that makes it easy to integrate 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.
The Windows XP user interface also makes it easier to test complex technology, as well as reduces mistakes. Familiar drop-down menus simplify measurement selection and menus are optimized for touch screen operation with single-click activation. Charting of data can be done directly on the analyzer. Users can integrate measured traces into Excel, Word, and PowerPoint files for reporting purposes.
Most common measurements, including channel power, ACPR, and occupied bandwidth (OBW), can be made with a single key. The MS2781B has a DVD-ROM and CD R/W drive, and two USB interfaces on the front panel for enhanced connectivity. An additional USB port, as well as GPIB and Ethernet interfaces, are on the rear panel to provide more flexibility.
The MS2781B has a delivery of 8-12 weeks ARO.
