13.3.2.2 Using an RF Switch
An RF switch allows you to automatically route and condition RF signals as required
from a single device in the test setup.
In the context of EMC measurements, using an RF switch can be useful for measure-
ment scenarios in which you apply a transducer set (different transducers for different
frequency ranges).
Without an RF switch, you would have to change the test setup and resume the mea-
surement deliberately every time a new transducer has to be applied. With an RF
switch, however, you can prepare the complete setup in advance and program the RF
switch matrix to switch automatically to a different signal path when a transducer break
occurs (and the transducer properties change). Manual changes of the test setup dur-
ing a measurement are no longer necessary.

Managing Datasets
Access: [SETUP] > "Transducer" > "Switch Control"
Information required to control an RF switch is stored in a dataset in the .xml file for-
mat.
This dataset is basically a program that remotely controls the RF switch to configure it
for each transducer range. The dialog box to manage datasets is made up out of a
table that shows all datasets available in the default directory of the R&S ESW or data-
sets that you have loaded from different file locations.
Creating a dataset
The "Add New" feature creates an empty dataset.
For more information about the corresponding dialog box, see "Programming a Switch
Matrix" on page 324.
