Instrument serial numbers
Agilent Technologies makes frequent improvements to its products to
enhance their performance, usability, and reliability. Agilent Technologies
service personnel have access to complete records of design changes for
each instrument, based on the instruments’ serial number and option
designation.
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 GPIB using the *IDN? command.
