The Keysight 346A, 346B, and 346C noise source produce noise output (power-on) when +28 V is applied. When it is off, there is residual noise due to thermal agitation in the noise source (power-off). These two noise levels are used to measure the gain and added noise of the device under test and, consequently, its noise figure. The 364 noise source family specification list the uncertainty of the ENR data.

All 3 models are provided with a BNC female connector for power input. The output connector is a male APC-3.5 on the standard noise sources. Type-N connectors are available as options for the Keysight 346A and 346B noise sources. In addition to these general characteristics, certain characteristics apply to the specific models.

The Keysight 346C noise source offers 10 MHz to 12 GHz coverage with a 16 dB ENR or 12GHz to 26.5GHz coverage with a 17dB ENR.

The Keysight 346C noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 26.5 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. Option K01 is a coaxial noise source and features coverage from 1 to 50 GHz with a 2.4 mm coaxial connector.

Model Overview
Model	Description
346A	The Keysight 346A noise source (10 MHz to 18 GHz) with a 6dB ENR is designed especially for accurate characterization of input-impedance-sensitive device
346B	The Keysight 346B noise source's high ENR (15dB), low SWR, and variety of connectors make it a general-purpose noise source for the range 10 MHz to 18 GHz.
346C	The Keysight 346C noise source offers 10 MHz to 12 GHz coverage with a 16 dB ENR or 12 GHz to 26.5 GHz coverage with a 17 dB ENR.
346CK01	The Keysight 346CK01 is the ideal companion to Keysight's noise figure solutions when working on high-frequency applications.
346CK40	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.
