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 8752C is now model number Agilent 8752C.
