To manage bandwidth extension setup files

The following procedure describes how to create, edit and save a bandwidth extension
setup file.

1. Open the bandwidth extension setup file-select dialog.

See steps (1) and (2) in 

"To load a bandwidth extension setup"

 

on page 17.

2. To create a bandwidth extension setup file, proceed as follows:

a) Select "New".
b) Enter the filename.
c) Select "Ok".

The file is created using the default configuration: Single R&S

 

SMW using both

ports and one power combiner.

3. To edit a bandwidth extension setup file, proceed as follows:

a) Select the file.
b) Select "Edit"

The "Bandwidth Extension Setup File Editor" dialog opens with settings to config-
ure RF ports and align the setup. See 

Chapter 4.2, "Setup file editor settings"

,

on page 31.
