Instrument Serial Numbers

Keysight makes frequent improvements to its products enhancing
performance, usability, or reliability. Keysight service personnel have access to
complete records of design changes to each type of instrument, based on the
instrument's serial number and option designation.
Whenever you contact Keysight about your instrument, have the complete
serial number available. This will ensure that you obtain accurate service
information.
A serial number label is attached to the rear of the instrument. This label has
two instrument identification entries: the first provides the identification
number for each option built into the instrument and the second provides the
instrument's serial number.
The serial number has two parts: the prefix (two letters and the first four
numbers), and the suffix (the last four numbers). Refer to the following figure.

The first two letters of the prefix identify the country in which the unit was
manufactured. The remaining four numbers of the prefix identify the date of the
last major design change incorporated in your instrument. The four digit suffix
is a sequential number and, coupled with the prefix, provides a unique
identification for each unit produced. Whenever you list the serial number or
refer to it in obtaining information about your instrument, be sure to use the
complete number, including the full prefix and the suffix.
The serial number is located on the rear panel serial sticker or when the
instrument is powered up, press Utility, Instrument Info, Diagnostic Info.
