General Information
Instruments Covered in This Manual
Instruments Covered in This Manual
The noise sources covered by this manual have a two-part serial number.
The first four digits and letter constitute the serial number prefix. The
last five digits form a sequential suffix that is unique to each noise
source. The prefix is the same for all noise sources of a particular
configuration. It will change when a design modification occurs. The
contents of this manual apply directly to those instruments having the
same serial number prefixes listed under SERIAL NUMBERS on the
title page.
A noise source manufactured after the printing of this manual may have
a serial number prefix which is not listed on the title page. This unlisted
serial number prefix indicates the noise source is different than those
documented in this manual. If manual changes are needed, the manual
for this newer noise source is accompanied by a Manual Changes
supplement. The supplement contains "change information" that
explains how to adapt this manual to the newer noise source.
In addition to change information, the supplement may contain
information for correcting errors in the manual. The supplement is
identified with the manual print date and part number, both of which
appear on the manual title page.
For information concerning a serial number prefix that is not listed on
the title page in the Manual Change supplement, contact your nearest
Agilent Technologies office.
Agilent/Hewlett-Packard 346 Noise Sources which were manufactured
before the printing of this manual will have a serial number prefix lower
than the one listed on the title page. Manual changes for these older
models are found in Chapter 2 “Manual Changes”.
NOTE Agilent Technologies are migrating their existing product serial numbers
to a new format. All new products use this new format. The format is the
first two letters signify the country of manufacture, for example, US
representing the USA, the next four numbers,the serial number prefix,
and the last five numbers form a sequential suffix that is unique to each
product. For example, US123456789, where 1234 is the prefix and 56789
is the suffix. The two letters MY represent Malaysia.
