Perform WLAN 802.11ac and 802.11ax transmitters one-button measurements with pass/fail tests as defined by IEEE WLAN 802.11 standards.


  • Support 802.11ac and 802.11ax 20/40/80/160 MHz and 80+80 MHz one-button standard-based measurements with pass/fail tests per the standard
  • Modulation analysis: up to 8x8 MIMO EVM measurement (only available with PXIe VXT M9421A/M9410A/M9411A)
  • Modulation format: QPSK, 16/32/64/128/256/1024 and 4096 QAM
  • Spectrum and power measurements: channel power, SEM, OBW, CCDF, spurious emission, Power vs Time, spectral flatness 
  • Modulation analysis measurements: constellation diagram, EVM, EVM vs. symbol, EVM vs. subcarrier, Burst & Signal Info, User Info (802.11ax), numeric results, and Demod bits etc. 
  • Performance: EVM floor up to -52 dB (0.25%) (nominal); Absolute power: up to ▒ 0.19 dB (at 95th percentile)
  • Support multi-touch user interface and SCPI remote interface programming
  • KeysightCare software support subscription included
  • Keysight supports tiered X-app models with N-models for UXA/PXA/PXE, E-models for MXA/EXA/MXE/VXT. The higher tiered X-app models can run at the lower platforms, which means N-models can run on all platforms, and E-models can only run on MXA/EXA/MXE/VXT.
