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).

346A
Noise Source
The Keysight 346A noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 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. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).

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.

346B
Noise Source
The Keysight 346B noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 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. The 346B's high ENR, low SWR, and variety of connectors make it a general-purpose noise source. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.

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.

Low Noise Prepolarized Microphone
378A04
-
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.
