The ultimate performance of our UXA signal analyzers lets you characterize today’s most challenging signals — fast-hopping, wideband, transient — in 5G, 802.11ax/ay, satellite, radar, electronic warfare, and more. You will be able to fully understand the purity of your design with industry-leading phase noise and wide spurious-free dynamic range.

  • Get wider (up to 1 GHz), deeper views of your most challenging signals
  • Measure the spectral purity of your design with industry-leading phase noise and 78 dBc spurious-free dynamic range across 510 MHz bandwidth
  • Extend RF input frequency up to 110 GHz with Keysight smart mixers and up to terahertz frequencies with third- party solutions
  • Capture intermittent signals with gap-free, real-time spectrum analysis
  • Capture lower-level spurious signals with an improved DANL low noise path
  • See more and take your design farther with the 14.1-inch screen


  • DANL @1 GHz: -174 dBm
  • Maximum Analysis Bandwidth: 1 GHz
  • Maximum Real-Time Bandwidth: 510 MHz
  • Phase Noise @1 GHz (10 kHz offset): -135 dBc / Hz
  • Type: Benchtop
