General purpose applications to measure noise figure up to 30 dB User calibrating the fullest dynamic range of an instrument before measuring high gain devices Use a 6 dB noise source for Measuring a device with gain that is especially sensitive to changes in the source impedance The device under test DUT has a very low noise figure The device noise figure does not exceed 15 dB Keysight offers three different families of noise sources and all may be used in conjunction with the NFA The smart noise sources simplify measurement set up and improve accuracy and reliability automatically downloading electronically stored calibration data to the instrument to save valuable time The 346 Series noise sources are the traditional and most cost effective solution offering the widest range of frequency coverage Lastly Keysight offers high frequency noise sources for customers making measurements above 26 5 GHz If one source does not include both frequency ranges a second source will be required A second noise source may also be necessary when measuring a non frequency translating device with low noise figure and high gain Noise source ENR Frequency range N4000A 4 6 6 5 dB 10 MHz 18 GHz SN N4001A 14 16 dB 10 MHz 18 GHz Sources N4002A 12 17 dB 1 10 MHz 26 GHz 346A 5 7dB 10 MHz 18 GHz Traditional 346B 14 16 dB 10 MHz 18 GHz Noise Sources 346C 12 17 dB 10 MH
