Perform power amplifier measurements with connection to the signal generator.


  • 30-Day Free Trial for X-Series Measurement Applications
  • Characterize power amplifier (PA) with pre-distortion applied in RF and millimeter wave, with simple and integrated multi-touch user interface
  • Provide smart link for automated signal generator closed loop control with power servo to auto-adjust PA output power
  • Extracts DPD model and apply Pre-distortion to linearize PA output with supported DPD model as Look-up table (LUT), Volterra Series, Memory Polynomial, or user-defined DPD model with MATLAB scripts
  • Show both Pre-DPD and Post-DPD measurement results in one screen, for ease of comparison. Easily switch between Pre-DPD and Post-DPD results
  • Support PA measurements with AM/AM, AM/PM, ACP, Delta EVM, Demod EVM (5G NR, LTE FDD, and 802.11ac/ax/be), Power vs Demod EVM
  • Supports multi-carrier measurements to show EVM results in single screen
  • Support frequency up to 44 GHz with 2 GHz bandwidth with UXA and VXG
  • Control the VXG and apply the DPD function directly to improve the PA/DPD measurement speed
  • Support Keysight signal studio waveform or user-defined waveform (txt, csv, bin, hdf, MATLAB file)
  • Support waveform processing with crest factor reduction with clipping & filtering or peak cancellation methods
  • Support M9484B VXG with 2-channel, or PXI VXT and AWG for PA Envelope Tracking (ET) measurement
  • 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
