Power Meter Operation
Contacting Agilent Technologies
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
• 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.
