Instrument serial number

Keysight makes frequent improvements to its products to enhance their
performance, usability, and reliability. Keysight service personnel have access to
complete records of design changes for each instrument. The information is based
on the serial number and option designation of each U8480 Series.
Whenever you contact Keysight about your U8480 Series, have a complete serial
number available. This ensures you obtain the most complete and accurate
service information. The serial number can be obtained from the serial number
label.
The serial number label is attached to the side panel of the U8480 Series. This
label has two instrument identification entries. The first provides the instrument
serial number and the second provides the identification number for each option
built into the instrument.
The serial number is divided into two parts: the prefix (two letters and the first four
numbers), and the suffix (the last four numbers).
– The prefix letters indicate the country of manufacture. This code is based on

the ISO international country code standard and is used to designate the
specific country of manufacture for the individual product. The same product
number could be manufactured in two different countries. In this case, the
individual product serial numbers would reflect different country of
manufacture codes. The prefix also consists of four numbers. This is a code
identifying the date of the last major design change.
