Product Overview

The 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 I

C 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 drive voltage.

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.
