The output port ("
Out
") can be switched to one of two input ports ("
In A
", "
In B
"). The
unused input port is terminated internally. The transmission is DC blocked. Failsafe
relays are used for switching. In the case of power loss, the primary input port
("
In A
") is routed to the output port. For measurement purposes, the monitoring
output port ("
Monitor
") is available.

The functionality of the module DEV 11-0034 is identical with the module
DEV 11-0014 (please refer to chapter 3.2.1), but the module is designed for a
different frequency range and for 75 Ohm with F connectors (instead of 50 Ohm
with SMA connectors).
