 Network Analyzers using PXI software

If the required frequency range of the calibration exceeds the operating frequency ranges of some calibration standards, use several standards to have the whole required frequency range covered. A calibration kit should contain several standards of each class (e.g. TRL LINE) with some specified frequency limits. Each of these standards will be applied for the measurements within its frequency limits. The total frequency band of all the standards should cover all the required frequency range of the calibration without “gaps”.

When several calibration standards of one class are used for calibration, subclasses should be assigned to these standards using the calibration kit editing function. The procedure of subclass assignment is described in Calibration Standard Class Assignment.


note

When assigning two or more subclasses to one class of calibration standards the calibration menu changes: the standard measurement softkey is replaced by the softkey, which opens the subclass menu containing the list of all the standards of this class.


Examples of using this method are given in the sections TRL Calibration Example Using Subclasses and Sliding Load Calibration Example Using Subclasses.
