Hewlett-Packard to Agilent Technologies Transition
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
number/name was HP XXXX the current name/number is now Agilent XXXX. For example,
model number HP 8720D is now model number Agilent 8720D.
