HIGHLIGHTS

The Keysight 346B noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty, which are reflections of the test signals. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.

  • Frequency range: 10 MHz to 18 GHz    
  • VSWR: < 1.3:1
  • Connectors: BNC (f) input bias / 3.5 mm (m)
  • Low SWR for reducing noise figure measurement uncertainty
  • Individually calibrated ENR values at specific frequencies
