The Ceyear 16606DA intelligent noise source is a device that can generate a random continuous spectrum signal. A well-operated noise source should have a stable output noise power and a homogeneous power spectral density within a specified frequency band. We, China Electronics Technology Instruments Co., Ltd (CETI as follows) provide a variety of solid-state coaxial noise sources in the frequency range of 10MHz to 40GHz, namely, smart and standard series, which have the advantages of wide frequency coverage, small output voltage standing wave ratio（VSWR）, and excellent flatness of output excess noise ratio, etc. The smart noise source adopts the I2C bus-technology to realize the automatic download and improve the measurement speed. Equipped with digital temperature sensor, it is convenient for the host to automatically monitor the change of ambient temperature and can be used to correct the temperature of the noise figure measurement and improve the measurement precision. Standard noise source requires +28V pulse voltage drive.
The solid-state noise source and noise figure analyzer are used together to provide a complete solution for the measurement of the noise figure of microwave millimeter wave frequencies. CETI has established a corresponding frequency band noise source calibration system to calibrate the excess noise ratio of noise source regularly.
