General Specifications
Specifications
The specifications in
are performance standards or limits against which
the SNS series smart noise source may be tested. These specifications for the
noise source are ONLY valid if the analyzer has been allowed to meet its specified
warm-up time.
The ENR expanded uncertainty analysis for noise source calibration is provided in
“Excess Noise Ratio expanded uncertainty (U(Y))”
The
“Supplemental characteristics”
on page 26 are not specifications but are
typical characteristics included as additional information.
