16603/16604 Series Noise Source
(10MHz～18GHz/26.5GHz/40GHz/50GHz)
Product Description
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 50GHz, 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
2
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 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.

Wide frequency coverage and excellent flatness of output excess noise ratio
The upper frequency limit of the series coaxial noise source can reach 50GHz. The frequency
coverage is wide and the flatness of excess noise ratio is good.
The value of excess noise ratio can be automatically loaded after the smart noise source
connecting with noise figure analyzer.
Smart noise source adopts I
2
C bus-technology with built-in electronic memory to store the data of
frequency-dependent excess noise ratio.
Real-time temperature detection
The smart noise source has a built-in digital temperature sensor, which can monitor the real-time
change of the ambient temperature, and can be used to correct the temperature of the noise figure
measurement and improve the measurement precision.
