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).

Low-Noise DC Bias
-
Imaging devices, such as CCDs, IR FPAs, and CMOS image sensors, require DC bias with very low electrical noise to prevent contamination of the image. Image quality can also be enhanced by carefully tuning each bias voltage to extract the maximum signal/noise ratio out of an array. Pulse Instruments has decades of experience providing DC bias supplies with the flexibility required tocharacterize and test a variety of devices while maintaining the noise immunity required for satellite and astronomy applications.
