346B
Noise Source
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; 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.

346CK40
Noise Source
The Keysight 346CK40 is the ideal companion to Keysight´s noise figure solutions when working on high frequency applications. Since it is broadband (1 GHz to 40 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source greatly reduces measurement uncertainty, which are commonly reflections of the test signals. This is a coaxial noise source with a 2.4 mm coaxial connector. ENR typically 14 dB at 1 GHz, decreasing to 5 dB at 40 GHz (typical).

Noise Parameters are the non-50Ω extensions of Noise Figure, and are an important modeling and model validation tool to understand how a device-undertest’s performance changes as a function of source impedance. Noise Parameter measurements are typically performedusing a Vector Network Analyzer (VNA) to measure the S-Parameters of the DUT, and a Noise Analyzer (either Noise Figure Analyzer NFA or Spectrum Analyzer SA) to measure the noise power of the DUT. Noise parameters are calculated from a combination of knownsource impedances, S-parameters and noise powers.
