04 | Keysight | N4000A, N4001A, N4002A SNS Series Noise Sources - Technical Overview
Accurate Noise Power
The output of a noise source, usually given in terms of Excess Noise Ratio (ENR), must
be known in order to make accurate noise figure measurements. Any uncertainty in the
ENR transfers into uncertainty of the measured noise figure, dB for dB. Keysight provides
accurate ENR calibration data with each noise source. ENR uncertainty and reflection
coefficients at each frequency point are provided as well.
The following is an example of calibration data for an N4001A noise source:
# ENR Data File
# Created by N8975A NFA Series Noise Figure Analyzer
# Serial Number GB40390000 Firmware Revision A.01.01
# 13:37:07 Mar 28, 2001
# Format is: Frequency (Hz), ENR (dB), ENR Unc (dB), # On Refl.Mag (lin), On Refl.Phase (deg),
