Keysight N9055EM0E Power Amplifier Measurement Application

Key Features and Specifications

  • 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 sricpts
  • 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 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 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.

Power Amplifier Measurement Application

Modern mobile communications, such as 5G NR and WLAN place new demands on linearity, bandwidth and power consumption in wireless components, mobile terminals or base stations. One of the most non-linear components is the PA (Power Amplifier). The design of the power amplifier must allow it to:

  • Increase spectral efficiency
  • Reduce distortion and non-linearity

N9055EM0E Power Amplifier measurement application is an integrated PA testing system mainly targeting 5G NR, WLAN, or other wideband PA test  scenarios. N9055EM0E is running inside Keysight X-series Signal Analyzers  which can connect Keysight Signal Generators for signal generation to make  both Pre-DPD and Post-DPD PA measurements as the typical measurements.
