The Keysight (Agilent) E6651A Mobile WiMAX Test Set is an integrated platform for RF characterization and protocol validation of IEEE 802.16e subscriber stations. It delivers instrument-grade signal generation and analysis across 330 MHz to 6 GHz, combining base station emulation with full RF parametric measurements in a single chassis. The system supports MIMO testing with dual downlink channels, protocol conformance validation per IEEE 802.16e-2005, and end-to-end functional verification including handover, security, and battery-life testing. A complete software suite enables automated test planning, real-time protocol debug, and WiMAX Forum-validated conformance workflows.
