Keithley Instruments Inc., a leader in solutions for emerging meas-urement needs, has expanded its powerful SignalMeister™ software platform to now include RF signal analysis along with RF signal generation. First introduced in 2007, SignalMeister software is now the only software package on the market that integrates signal generation and analysis into one package for unmatched speed and simplicity. Furthermore, SignalMeister now has the capability of generating and analyzing both single-input single-output (SISO) and multiple-input multiple-output (MIMO) signals in the same environment. With SignalMeister software, research, design and test engineers can quickly and easily create and analyze signals with a powerful yet easy to use block diagram-based, graphical user interface. In addition, the SignalMeister RF Communications Toolkit now supports the latest wireless, MIMO protocol standards, WiMAX Wave 2 and 802.11n WLAN. It also provides additional complex functionality such as WLAN channel modeling, beamforming, simulation studies, along with a rich set of IQ operations, and full utilities for data import and export.
