The Keysight 346CK01 is the ideal companion to Keysight´s noise figure solutions when working on high-frequency applications. Since it is broadband (1 GHz to 50 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. This is a coaxial noise source with a 2.4 mm coaxial connector. ENR typically 20 dB at 1 GHz, decreasing to typically 7 dB at 50 GHz.

  • Frequency range: 1 GHz to 50 GHz
  • Connectors: BNC (f) input bias / 2.4 mm (m)
