Standard Definitions

Nominal Standard Definitions

Nominal Standard Definitions

Standard definitions provide the definitions needed to mathematically model the electrical 
characteristics (delay, attenuation, and impedance) of each calibration standard. The 
nominal values of these definitions are theoretically derived from the physical dimensions 
and material of each calibration standard, or from actual measured response. These values 
are used to determine the measurement uncertainties of the network analyzer. The 
standard definitions in 

Tables A-7

 through 

A-9

 list typical calibration kit parameters used 

to specify the mathematical model of each device. This information must be loaded into the 
network analyzer to perform valid calibrations. Refer to your network analyzer user’s 
documentation for instructions on loading calibration definitions.

NOTE

The values in the standard definitions table are valid 

only

 over the specified 

operating temperature range.

Setting the System Impedance

This kit contains only 50 ohm devices. Ensure the system impedance (Z

0

) is set to 50 ohms. 

Refer to your network analyzer user’s documentation for instructions on setting system 
impedance.
