Scope

This system table is suitable for the calibration of radio frequency and microwave noise measuring instruments. It specifies the procedure for transferring the values of noise power spectral density or noise temperature, expressed in units of W/Hz or Kelvin (denoted by K), from the measurement reference to the working measurement instruments through measurement standards, and indicates errors and basic calibration methods, etc.
The high-temperature noise calibration system consists of three parts: measurement reference instruments, measurement standard instruments, and working measurement instruments.
The low-temperature noise calibration system consists of two parts: measurement reference instruments and working measurement instruments.
