Keysight N4002A SNS Series Noise Source

Manufacturer: Keysight
Model Number: N4002A
The Keysight SNS Series of noise sources work in conjunction with NFA Series noise figure analyzers, X-Series signal analyzers and ESA E-Series spectrum analyzers. To simplify measurement set-up and improve accuracy these noise sources automatically download electronically stored calibration data to the compatible noise figure measuring analyzers. The noise sources also have the capability to automatically measure their own temperature so that compensation can be applied to the calibration data. These capabilities increase the overall reliability and accuracy of noise figure measurements.


  • 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.
