Product Overview

A noise source is a device capable of generating random continuous spectrum signals. An excellent noise source should possess stable output noise power and uniform power spectral density within the specified frequency band. CETC SiYi Technology Co., Ltd. can supply a variety of coaxial noise sources across the frequency range of 10MHz to 50GHz. The products include both intelligent and standard series, offering advantages such as wide frequency coverage, low standing wave ratio at the output ports, and good flatness of the output super-noise ratio.

The intelligent noise source utilizes I2C bus technology for automatic download of ultra-noise ratios, enhancing measurement speed; it is internally equipped with a digital temperature sensor for the host to automatically monitor changes in ambient temperature. This is used for real-time temperature correction in noise coefficient measurement, improving measurement accuracy. Standard noise sources require +28V pulse voltage drive.

Noise source and noise factor analyzer are used together to provide a complete solution for noise factor measurement in the microwave millimeter wave frequency band. CETC SIYI Technology Co., Ltd. has established a noise source over-modulation ratio calibration system for the corresponding frequency band, which can accurately calibrate the over-modulation ratio of the noise source.
