SNS Series Noise Source 10MHz-26.5GHz (ENR 15dB) The Agilent (now Keysight) N4002A is a Noise Source of the SNS series and was designed to measure DUT noise figures reliable and accurately up to 30 dB from 10 MHz to 26.5 GHz. This noise source comes with an APC 3.5 connector as standard. ENR (nominal): 15 dB, range: 12 - 17 dB Electronic storage of Excess Noise Ratio (ENR) calibration data decreases the opportunity for user error Automatic download of ENR data to the NFA speeds overall set-up time Temperature compensation improves measurement accuracy leading to tighter specification of device performance The SNS Series of noise sources work in conjunction with: NFA Series noise figure analyzers X-Series signal analyzers ESA E-Series spectrum analyzers
