Keithley is developing a WiMAX device production test solution for two 802.16e WiMAX devices from Fujitsu Microelectronics. This WiMAX RF SISO/MIMO manufacturing test configuration features Keithley’s RF test solutions, the Model 2820 RF Vector Signal Analyzer and Model 2920 RF Vector Signal Generator. The configuration will enable Fujitsu to perform a set of Tx and Rx test sequences. The system’s expandability also will offer Fujitsu the ability to test its WiMAX devices in both SISO and MIMO mode.

Keithley’s WiMAX solution is built on a hardware platform that enables the addition of support for new signal standards and methodologies (such as 802.16e mobile WiMAX Wave 2 testing of up to 8x8 MIMO channels) without requiring users to purchase expensive hardware upgrades or new instrumentation. Keithley MIMO systems based on the Model 2820 RF Vector Signal Analyzer and Model 2920 RF Vector Signal Generator. Such a system can accommodate the generation of MIMO signals with under 1ns of timing alignment and less than 0.1º of phase jitter. Similarly, the system’s multiple Model 2820 analyzers can acquire signals synchronized to fewer than 250ps of time record jitter.
