16603/16604 Series Noise Source
10MHz~18GHz/26.5GHz/40GHz/50GHz
Product Overview
A 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 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.
