Figure 6-21: Typical setup using an external frontend
For details on setting up the external frontend, see the documentation of the used
device.
Multiple connections to a single frontend
The FE50DTR-type frontend has an RX and a TX signal path. The RX signal path uses
the "RF A" and "IF Out A" connectors and is connected to the R&S
FSV/A. The TX
path uses the "RF B" and "IF In B" connectors and can be connected to a signal gener-
ator. With the latest firmware, both a signal generator and a R&S
FSV/A can use the
same frontend at the same time.

Figure 6-22: Typical setup for multiple instruments connected to one external frontend
Exclusive use during specific tasks
For specific tasks, the external frontend is blocked exclusively for one connected
instrument. In particular:
●
When updating the frontend firmware
●
During initial connection of an instrument to the frontend, when the device data is
exchanged.
If such a task is performed while another instrument that is connected to the same
frontend is performing a measurement, an error occurs ("Device busy"). In this case,
the running measurement is aborted. The instrument remains connected, though, and
you can restart the measurement once the frontend is available again.
Furthermore, only one instrument can access the frontend to change settings at a time.
While one connected instrument changes hardware settings on the external frontend,
the frontend is locked for the other connected instrument. The second instrument gets
a "Device busy" message and must retry when the frontend is available again.
