Noise source offerings
346 Series noise sources work with the full range of Keysight noise figure solutions. They
are categorized by frequency coverage as well as excess noise ratio (ENR). The SNS
Series of noise sources, or smart noise sources, can be used in conjunction with the
X-Series signal analyzers, NFA, and ESA spectrum analyzer. The SNS noise sources rep-
licate the ENR output and frequency coverage of the 346 Series noise sources, however
with the SNS Series, ENR data is stored in an EPROM and is automatically downloaded
to the instrument, eliminating the need to manually enter the values into the calibration
table at each cardinal frequency point. In addition, a thermistor is built into the sensor
to continually update the analyzer with the correct temperature, delivering automatic
temperature compensation/correction within the measurement’s source.
The U7227A/C/F USB preamplifiers, used with an X-Series signal analyzer, reduce un-
certainty of Y-factor noise figure measurements up to 44 GHz.

lyzer may be more suitable than the Y-factor method.
