The sweep modules generate the transmit (TX) and receive (RX) signals for the
measurement. Normally their output is a linearly swept frequency sweep.
In the newer WERA versions (since 2009) just the Rx sweep is active during acquisition.
The Tx is used for calibration only and can be used as a “spare part” in case of a failure of
the Rx sweep.
The sweep dummy is an empty housing in an unused sweep module slot of the FCR. Its
purpose is to keep the correct airflow and thus the proper cooling of the other modules

The state machine synchronises data acquisition.
After a restart of the system the illuminated LED indicates that the system is operational.
To turn on the LED the RTU needs to mount directories on the user pc.
