This manual may contain references to HP or Hewlett-Packard. Please note that Hewlett-Packard’s
former test and measurement, semiconductor products and chemical analysis businesses are now part of
Agilent Technologies. To reduce potential confusion, the only change to product numbers and names has
been in the company name prefix: where a product name/number was HP XXXX the current name/
number is now Agilent XXXX. For example, model number HP8648 is now model number Agilent
8648.
Please note that this document was updated in April 2011 to revise the Mixer Non-Linearity
