Noise Source, 1 GHz up to 40 GHz
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).

Broadband Coaxial Noise Sources
-
Our integrated noise modules contain all the required biasing circuitry and only need a positive voltage to activate for an easy installation. Since they typically do not contain amplification, the raw noise output from the diode is seen at the output of the module resulting in a maximum ENR of approximately 35dB. Primary applications include system built-in test and laboratory use.

Precision Current Sources
-
HighFinesse Precision Current Sources have been developed for experiments and quantum technologies in the areas of cold-atom and solid state physics. The linearly regulated BCS (Bipolar Current Source) and UCS (Unipolar Current Source) series deliver highly stable, low noise source currents for high precision magnetic field control. The current output is floating or is on a used defined potential. Ultrafast response to control signals and trigger functions, clear grounding, connection and signal isolation schemes make the integration of the current sources into complex experimental systems easy.
