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.

Principles of Microwave Connector Care

Proper connector care and connection techniques are critical for accurate,
repeatable measurements

Refer to the calibration kit documentation for connector care information.
Prior to making connections to the network analyzer, carefully review the
information about inspecting, cleaning and gaging connectors

Having good connector care and connection techniques extends the life of these
devices In addition, you obtain the most accurate measurements

This type of information is

typicaIly

located in Chapter 3 of the calibration kit

maMal8.
F’or
