The 802.11ax test solution combines multi-channel test instruments with ready-to-use software that supports required 802.11ax test parameters, from SISO to 8x8 MIMO, across R&D, design verification, and manufacturing test. Users can generate waveforms for all HE PPDU formats with flexible resource unit (RU) configurations for multi-user OFDMA, long OFDM symbols for extended range PPDU, and dual carrier modulation (DCM). The analysis software provides automatic demodulation of single and multi-user signals, displaying results for each user’s RU allocation. The 802.11ax system software simplifies the configuration of both source and analyzer for complex MIMO measurements. The system is also compatible with some chipset vendor software tools.

The test solution includes M9421A VXT PXIe Vector Transceivers — a vector signal generator and signal analyzer in a single PXIe module covering 60 MHz to 6 GHz frequency with up to 160 MHz bandwidth. It supports up to 4 channels in one PXIe chassis and 8x8 MIMO in two synchronized chassis. The VXT provides the necessary EVM performance to meet the stringent requirements for testing 1024QAM modulation quality for validating chipsets, power amplifiers, and WLAN devices. Additional components can be added to the system to configure it for performing regulatory tests, including blocking, co-existence, and adaptive testing for WLAN devices.
