USB Smart Noise Sources

Noise Sources Designed to Meet Specific Needs

Keysight Technologies USB smart noise sources works in conjunction with

• NFA series noise figure analyzers

• X-series signal analyzers

• Vector network analyzers

• FieldFox

The USB (USB-TMC compliant) connectivity that comes with smart features of automatically download of electronically stored calibration data and temperature sensing. To simplify measurement set-up and improve accuracy this noise source automatically downloads electronically stored calibration data to the compatible Keysight noise figure measuring analyzers. The noise sources also have the capability to automatically measure their own temperature so that compensation can be applied to the calibration data. These capabilities increase the overall reliability and accuracy of noise figure measurements.

USB Smart Noise Sources Key Features

• Automatic download of ENR data to the analyzers significantly speeds up the overall setup time 

• Electronic storage of Excess Noise Ratio (ENR) calibration data decreases opportunity for user error 

• Temperature sensing improves measurement accuracy, leading to tighter specification of device performance

U1832/3x for accurate and reliable noise figure measurement of a device up to 60 GHz

The U183x USB smart noise source was designed to measure DUT noise figures reliably and accurately up to 30 dB from 10 MHz up to 60 GHz. It serves as an ideal usage for general purpose use with low reflection coefficient and a nominal ENR value of 5/10/15 dB.

Accurate noise power

The output of a noise source, usually given in terms of Excess Noise Ratio (ENR), must be known to make accurate noise figure measurements. Any uncertainty in the ENR transfers into uncertainty of the measured noise figure, dB for dB. Keysight provides accurate ENR calibration data with each noise source. ENR uncertainty and reflection coefficients at each frequency point are provided as well. 

Specifications

Specifications refer to the performance standards or limits against which the U1832/3x USB smart noise sources are tested. These specifications for the noise sources are ONLY valid if the analyzers have been allowed to meet its specified warm up time. Typical characteristics are included for additional information only and they are not warranted specifications. 

Environmental Specifications

Samples of this product have been type tested in accordance with the Keysight Environmental Test Manual and verified to be robust against the Environmental stresses of Storage, Transportation and Enduse; those stresses include, but are not limited to, temperature, humidity, shock, vibration and altitude conditions. The primary source of Keysight Environmental Test standards is the International Electrotechnical Commission (IEC) standards.
