Keysight PNA Hardware Change History

 

When Keysight's PNA Network Analyzers are first introduced, they contain the most current technology available. In our environment of high speed technology innovation and evolution, this current technology can become obsolete in just a few years. So Keysight often needs to change the internal design of our products to incorporate newer technology. If these changes ever impact the compatibility of other internal parts, Keysight will change the number sequence in the product serial number to note this change. This listing below outlines the changes made in our PNA products which were significant enough to require a change to the serial number sequence.

Keysight's PNA Network Analyzers come with a 10-character serial number. The first two characters indicate the country of manufacture. The next four numbers indicate the year and week the number sequence started. These first six characters are collectively known as the serial prefix. The last four numbers are the numbering sequence for the product, and this is referred to as the serial suffix.

Note: Keysight shipped PNA Network Analyzers with the Windows XP operating system from 2002 to April 2014. Since April 2014, all PNAs have shipped with the Windows 7 operating system.
