Whenever you contact Agilent Technologies about your power meter have
a complete serial number available. This will ensure that you obtain the
most complete and accurate service information. The serial number can be
obtained by:
• interrogating the power meter over the GP-IB using the *IDN?
command.
• from the front panel by selecting
.
Version
• from the serial number label.
The serial number label is attached to the rear of each Agilent
Technologies instrument. This label has two instrument identification
entries. The first provides the instruments 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.
• The suffix indicates an alpha numeric code which is used to ensure
unique identification of each product throughout Agilent
Technologies.
