This application note provides a
high-level overview of the differ-
ences between the Agilent 662xA
and the Agilent N67xx in order to
help current 662xA owners easily
convert from their Agilent 662xA to
an Agilent N67xx. This application
note has been designed to be
used in conjunction with the
Agilent 662xA Operation Manuals
and datasheets as well as the
Agilent N6700 User’s Guide and
data-sheets
ment for any of the manuals and
it is recommended that a copy of
all the documentation mentioned
above be handy for reference
when reading this document.

Three areas will be discussed
in this document: electrical,
programming/interfacing, and
mechanical. These sections will
cover such topics as the power
supply’s output power and pro-
tections (electrical), command
compatibility and calibration
(programming/interfacing), as
well as size and connector type
(mechanical).
A side-by-side comparison of
the specifications and other
relevant information has been
provided in
convenience.
