 <p>A calibration kit is a set of physical calibration standards for a particular 
 connector type. The magnitude and phase response of the calibration standards 
 (i.e. their S-parameters) must be known or predictable within a given 
 frequency range. </p>
 <p>The standards are grouped into several types (open, through, match,...) 
 corresponding to the different input quantities for the analyzer's error 
 models. The standard type also determines the equivalent circuit model 
 used to describe its properties. The circuit model depends on several 
 parameters that are stored in the cal kit file associated with the calibration 
 kit. </p>
 <p>As an alternative to using circuit models, it is possible to describe 
 the standards by means of S-parameter tables stored in a file.</p>
 <p>The analyzer provides a large number of predefined cal kits but can 
 also import cal kit files and create new kits: </p>
