Key Specifications
Definitions
–– Specifications describe the performance of parameters covered by the product war-
ranty.
–– 95th percentile values indicate the breadth of the population (≈2 ) of performance
tolerances expected to be met in 95% of cases with a 95% confidence. These values
are not covered by the product warranty.
–– Typical values are designated with the abbreviation "typ." These are performance
beyond specification that 80% of the units exhibit with a 95% confidence. These
values are not covered by the product warranty.
–– Nominal values are designated with the abbreviation "nom." These values indicate
expected performance, or describe product performance that is useful in the ap-
plication of the product, but is not covered by the product warranty.
Analyzer noise figure is computed from the specified DANL. See specifications on follow-
ing pages for further explanation.
Noise figure for the combination of USB preamp and analyzer is
NF_sys = 10 * Log (F_preamp + (F_analyzer- 1)/G_preamp)
The noise figure and gain of the preamp are specified and warranted.
Analyzer VSWR is characterized to the 95th percentile but not measured and warranted.
USB preamp VSWR is measured and warranted and becomes the input VSWR of the
measurement system when used.
Instrument uncertainty is defined for gain measurements as uncertainty due to relative
amplitude uncertainties encountered in the analyzer when making the measurements
required for the gain computation.
The noise figure measurement application is not specified for use below 10 MHz. Instru-
ment uncertainty will nominally be the same as the 10 MHz to 3.6 GHz specifications;
however, performance is not warranted. Instrument uncertainty for gain is characterized
to the 95th percentile above 3.6 GHz.
These notes apply to the following specifications. For more information on configuring
an X-Series signal analyzer for noise figure measurements, depending on the DUT noise
figure gain, see the Noise Figure Measurement Guide, literature number N9069-90006.
