Millimeter-Wave Noise Source, R-band, 26.5 to 40 GHz
R347B
Noise Source
The Keysight R347B noise source covers a 26.5 to 40 GHz frequency range. This waveguide noise source allows you to make accurate and convenient noise figure measurements on millimeter-wave devices. The R347B provides highly precise broadband noise at the input of the system or component under test. The noise figure meter then processes the ON/OFF ratio of noise power present in the system IF, and provides an accurate reading of noise figure and gain. The R347B noise source has remarkable ENR stability over time, which allows longer recalibration cycles and more accurate noise figure measurements.

Noise Source, 1 GHz up to 50 GHz
346CK01
Noise Source
The Keysight 346CK01 is the ideal companion to Keysight´s noise figure solutions when working on high frequency applications. Since it is broadband (1 GHz to 50 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, which are reflections of the test signals. This is a coaxial noise source with a 2.4 mm coaxial connector. ENR typically 20 dB at 1 GHz, decreasing to typically 7 dB at 50 GHz.

Noise Dose Meters
-
Here you will find a full range with an industrial standard noise dose meter to suit every requirement. With the portable noise dose meter you can carry out measurements quickly to gain control of a situation or to set the device to take timed measurements. The noise dose meter is important for all industries, especially by using it as a mobile device which is able to assess office stress levels or street noise levels.Often problems arise from noisy neighbors or if bars and restaurants are in residential areas and produce noise levels after 10pm in excess of what local laws permit. We, of course, can assess which noise dose meter you require in relation to the issue you have and the relating laws. We also have microphone extension cords, tripods, calibrators and calibration certificates for most models of noise dose meter.
