the right noise source for your specific needs
Whether you are working with systems, subsystems, subassemblies, or discrete devices, each of your components adds noise that affects the overall performance of your receiver. By measuring and reducing noise figure, you can give your components a competitive edge.
The 346 series of broadband noise sources has been designed to cover the majority of measurement applications with a range of frequencies, Excess Noise Ratio (ENR), and coaxial connector types.
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.
