The Port4PrefixToUse key has two purposes. First it specifies that port 4 of the PNA will be used in the measurement. Second it defines the expected prefix for data files associated with PNA port 4 measurement and characterization files.

The value of this key must be an alpha numeric string that does not begin with a number.

For a more details on short, open, load measurements see ShortOpenLoad Characterizations.
