About This Chapter
This chapter contains specifications and characteristics for the Agilent E7403A
spectrum analyzer. The distinction between specifications and characteristics is
described as follows.
•Specifications desc ribe the performance of parameters covered by the produc t
warranty. (The temperature range is 0 °C to 55 °C, unless otherwise noted.)
•Characteristics describe pr oduct per forman ce that i s useful in th e appli cati on of
the product, but is not covered by the product warr anty .
•T ypical performance describes additional product performance inf ormation
that is not covered by the product warrant y. It is performance beyond
specification tha t 80% of the unit s e xhibit with a 95% conf idence leve l over the
temperature range 20 to 30 °C. Typical performance does not include
measurement uncertainty.
•Nominal values indicate the expecte d performance, or describe product
performance that is useful in the application of the product, but is not covered
by the product warranty.
The following conditions mus t be met for the analyz er to meet its specifications.
o The analyzer is within the one year calibration cycle.
