Keysight (Agilent) 346B

Noise Source, 10 MHz to 18 GHz, nominal ENR 15 dB
Contact us for pricing and availability.
The Agilent 346B noise source is the ideal companion to Agilent''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; reflections of test signals. The 346B''s high ENR, low SWR, and variety of connectors make it a general-purpose noise source. 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
  • Calibration supplied on floppy disk for easy loading into NFA Series Noise Figure Analyzers
