Data Sheet
Specifications
The complete Agilent Technologies 4285A specifi-
cations are listed below. These specifications are
the performance standards or limits against which
the instrument is tested. When shipped from the
factory, the 4285A meets the specifications listed
in this section. The specification test procedures
are covered in Agilent 4285A Maintenance Manual
(Agilent Part Number 04285-90030).
