Instrument Identification

Agilent Technologies instruments are identified by a 10-digit serial number. The format is described as follows: first two
letters indicate the country of manufacture. The next four digits are a code that identify either the date of manufacture or of
a significant design change. The last four digits are a sequential number assigned to each instrument.
Item Description
The first two letters indicates the country of manufacture, where US = USA; MY = Malaysia; SG =
MY
Singapore.
This is a code that identifies either the date of manufacture or the date of a significant design change.
4100
The last four digits are a unique number assigned to each power supply.
0101
Older serial number formats used with these instruments had a two-part serial number, i.e. 2701A-00101. This manual also
applies to instruments with these older serial number formats. Refer to Appendix A for backdating information.
