Standard Definitions

Nominal Standard Definitions

Standard definitions provide the constants needed to mathematically model the electrical

characteristics (delay, attenuation, and impedance) of each calibration standard. The

nominal values of these constants 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 Table A-3 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’s user’s guide for

instructions on loading calibration constants.

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 75 ohm devices. Ensure the system impedance (Z

) is set to 75 ohms.

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