zSeries PA/FEM (Discontinued)

Power Amplifier/Front-End Module Design Test Solution

zSeries PA/FEM is a fully-integrated hardware and software test solution combining 7.2 GHz VSG/VSA for accurate characterization and testing of the existing and the latest Wi-Fi standard 802.11ax PA/FEM components for use in mobile devices.

Covering wide measurement bandwidths useful for digital pre-distortion (DPD) testing, the FEM solution guarantees low noise and distortion necessary for validating the high efficiency Wi-Fi 6 1024QAM devices.

Meeting the exponential rise in the number of Wi-Fi capable devices in the market, the zSeries offers reduced time-to-test from weeks to hours or days.


  • Lab-in-a-Box configuration
  • Seamless hardware and software enhancements using a modular PXIe platform
  • Reduce time-to-test from weeks to hours or days
  • Test apps to setup complex tests for PA/FEM characterization and design verification without code

Advanced Software Integration Tools & Support

  • Graphical User Interfaces (GUI) for real-time “bench-top” interactive operation for RF designers and field application engineers
  • Support for C/C++, LabVIEW, Matlab, TCL and Python programming environments with example code and projects
  • DPD capabilities for rapid PA linearity characterization
  • Envelope Tracking characterization measurements for power efficiency maximization

All solutions are adaptable and re-configurable to provide you with the greatest flexibility for your testing requirements.

Key Specifications

  • Best-in-industry residual EVM performance: <-50 dB, required for 802.11ax PA/FEM tests
