Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 12179-1990 "Noise generator General technical conditions" and GB/T 12280-1990 "noise generator test Test Methods. " Compared with GB/T 12179-1990 and GB/T 12280-1990, the main changes are as follows. --- Original two standards into one standard; --- Delete the original standard and reference standard is no longer used in the existing terms and definitions, and the content of some of the terms modify; --- Remove the "excess noise ratio test test noise generator and a gas discharge stability of the amount of" "power consumption test" to Sum Test methods (see GB/T 12280-1990); --- Added "output excess noise ratio Uncertainty Measurement and Analysis," "excess noise output change amount" compared with the temperature "ultra-noise ratio with the drive output Voltage variation "" output "requirements analysis and test methods (see 4.10,5.12); --- Updated the "Security" "environmental compatibility", "Transport Packaging", "Electromagnetic Compatibility" "reliability" of the requirements and test methods (see Chapter 4, Chapter 5); --- Update "Quality inspection rules" in the part (see Chapter 6).

3 Terms and Definitions

The following terms and definitions for use in the present document. 3.1 Noise noise Disrupt or interfere with the useful signal disturbance, it makes disturbed or distorted to make it through the signal transmitted over the network. Note. A common noise is generated by superposition of a large number of short pulses of random processes, noise power distribution in line with the laws of probability theory, statistical methods can feed Processing. 3.2 Thermal noise thermalnoise Conductor in certain thermodynamic state arising in random electrical fluctuation. It is composed of irregular conductor free electron thermal transport Movement caused by its size depends on the thermodynamic state of the object, approximately evenly distributed throughout the RF and microwave frequencies, the load into the match funding With power is directly proportional to the bandwidth of the band. 3.3 Owned by noise power availablenoisepower Noise generator can be transmitted to the maximum power load. 3.4 Funded by the noise power spectral density spectraldensityforavailablenoisepower Owned by units of the noise power within the bandwidth. 3.5 Noise temperature noisetemperature When the noise generator generates the same noise power which the physical temperature of the resistor. Expressed in Kelvin (K). 3.6 Standard noise temperature referencenoisetemperature 290K noise temperature, usually represented by T0. ......
