.jpg) August 13, 2008 - Keithley Instruments published a poster that illustrates the key measurement tools and software analysis techniques required for measuring complex WiMAX signals. The poster provides a clear illustration for making "easy signal creation and analysis" of WiMAX signals, arguably the most complex modulation scheme in the world. WiMAX signals encompass multiple technologies into one very versatile system, including bandwidths in excess of 20MHz, configurations with more than 2000 subcarriers, high peak-to-average power ratios, and both SISO and MIMO radio configurations. The poster builds on the capabilities of a variety of new Keithley signal creation and analysis tools that extend its RF test capabilities to include WiMAX signal testing. Keithley's RF test solutions are based on the company's award-winning Model 2820 RF Vector Signal Analyzers and Model 2920 RF Vector Signal Generators. Because these test instruments rely on a next-generation DSP-based Software-Defined Radio (SDR) architecture, they are capable of making extremely high speed measurements both thoroughly and accurately. The SDR architecture enables Keithley's highly flexible offering with instruments that are easy and less costly to upgrade as new wireless and cellular standards are introduced. Keithley's test systems provide frequency coverage from 400MHz to 4GHz and to 6GHz if WLAN measurements are needed. The poster highlights the powerful RF signal analysis capabilities included in Version 2.0 of Keithley's SignalMeister™ Waveform Creation Software. Version 2.0 supports creation of the entire range of signals in accordance with WiMAX and WLAN wireless connectivity standards and 3GPP and 3GPP2 cellular standards. First introduced in mid-2007, SignalMeister is a PC-based object-orientated waveform creation tool that allows engineers to create highly complex signals required for today's RF testing needs quickly and flawlessly. SignalMeister is the only waveform creation software tool available that uses an object-oriented graphical interface that is optimized for MIMO signals, allowing engineers to easily create basic and complex waveforms.
