Fujitsu Microelectronics. The manufacturing test setup, which features Keithley s Model 2820 RF vector signal analyzer and Model 2920 RF vector signal generator, will enable Fujitsu to perform a set of Tx and Rx test sequences and also test WiMAX devices in both SISO (single input, single output) and MIMO (multiple input, multiple output) modes. The system can generate MIMO signals with under 1 ns of timing alignment and less than 0.1° of phase jitter.rn"WiMAX is quite possibly the most complex modulation scheme in the world, encompassing multiple technologies, and this complexity has made testing a challenge for manufacturers," said Mark Hoersten,VP of business development for Keithley. "Keithley's WiMAX test solution will enable Fujitsu Microelectronics to test in any frequency band between 400 MHz and 6 GHz faster and more easily than any competing offering."
