Performance backed by Agilent’s reputation and manufacturing experience
Every Agilent Technologies’
signal generator meets specifications that would reject
most other signal generators
Before any Agilent Technologies’ signal
generator is introduced, specifications are
set to assure that the product will perform
consistently for your application. The
specification setting process is reflective
of the quality that Agilent has always
strived to deliver. An explanation of Agilent’s
specification setting process will show the
confidence that you can have when
selecting an Agilent Technologies
signal generator.
The model used for specification setting is
illustrated in the above right figure. The
following text defines each element in
the figure.
• Production margin is the difference
between the average product performance and the test line limit (TLL). This
TLL is the pass/fail limit used by the
production line at final test under
standard environmental conditions.
• Delta environmental represents the
possible change in performance over
the environmental extremes (e.g.,
temperature and humidity).
• Drift represents the change in performance over the calibration period.
• Measurement uncertainty accounts for
possible measurement errors in the
equipment used to characterize the
signal generator.
• Customer guardband represents any
additional margin necessary to ensure a
worst case scenario.
This process means that whether the signal
generator is placed in a high temperature
environment such as at the top of a rack of
equipment or a well controlled environment,
the performance stated in our specifications
can be relied on for your most exacting
applications. This process guarantees that
the signal generator is introducing the
minimum error possible in the measurements you are performing.
Typical performance
Since some applications push the limits
of specifications, Agilent Technologies
also provides data that indicates typical
performance. This typical performance is
generally set at the test line limit (TLL),
which is significantly better than the warranted specification. Use the typical data
when comparing different products, or when
your application pushes the limit on a given
specification. The following information
highlights typical performance for the
most common areas of interest for the
8644B, 8664A and 8665B.
