Introduction
This specification based JJF 1071-2010 "national measurement calibration specifications write rules" Writing, terminology and measurement
Uncertainty Evaluation follow JJF 1001-2011 "common measurement terms and definitions" and JJF 1059.1-2012 "measure
Uncertainty in that "the two specifications.
This specification instead of JJG839-1993 "noise figure meter (pointer)." JJG839-1993 been unwell
Existing instruments should be measured, the entire contents of this specification were consolidated with modifications.
This specification relates frequency accuracy of the noise figure analyzer, noise figure, gain and noise figure of the machine,
Y coefficient jitter, noise calibration source drive voltage and the input port reflection coefficient modulus and other parameters.
The calibration specifications in frequency accuracy calibration, three calibration methods are given, respectively, the signal source sweep method, noise
Noise figure analyzer sweep method and source 3dB method to suit different types of noise figure analyzer calibration; in noise
Sound calibration coefficients are given three calibration methods, were step attenuator law, power meter and Alternative comparison.
The specification for the previous release conditions.
JJG839-1993 noise figure meter (pointer).
