Noise Source, 1 GHz up to 50 GHz
346CK01
-
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 Figure Measurements With Vector Correction
S95029B
-
The S95029B noise figure application enables high-accuracy noise figure and noise-power measurements of amplifiers, frequency converters, and mixers by using the Keysight vector-source-correction technique. Using a source-impedance tuner to remove the effects of imperfect system-source match, this technique produces higher accuracy results than Y-factor method and other cold-source implementations--especially for in-fixture, on-wafer, and automated-test environments.

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.
