5.2.1.2 Creating a Cable Model
The R&S FSH provides two ways to define customized cable models.
The first way is to define a cable model with the "Cable Model Editor" that is part of the
R&S FSH4View software package. The R&S FSH4View is delivered with the
R&S FSH. With this software, you can define a cable model on a PC and then transfer
it to the R&S FSH. Then you can select it just like any other predefined cable model.

Saving and Loading Instrument Settings and Measurement Results
If you do not have access to a PC, but still need a cable model that is not stored on the
R&S FSH, you can also define the characteristics of a cable temporarily on the
R&S FSH itself. It is not possible to save these in a data set, however. They are lost as
soon as you change them or load another cable model.
