5.2.12 RF Switch Module R&S OSP-B131
The module R&S OSP-B131 is designed for high power RF switching. The OSP-B131
contains the following relay configuration:
●
2 x SPDT switches with N-connectors
The module is designed for independent control of both relays.
The relay is a failsafe type; i.e. a RF connection is provided from the terminal C
(Common) to the position NC (normally closed) with no voltage applied to the relay. To
maintain a RF connection between the terminal C (Common) and the position NO
(normally open), a continuous voltage is to be applied to the relay.
Figure 5-38: Module R&S OSP-B131
The relays are mounted directly in the OSP-B131 front panel. All the RF connectors
are N female types. All relays are connected via a short cable to a printed circuit board;
this way the module is of compact size.
The OSP-B131 module is supplied with power and controlled from the OSP120 via a
single interface connector on the OSP-B131 printed circuit board. The connection to
the OSP120 is done via a single connection cable.
The OSP-B131 module is equipped with on board memory to store the necessary
configuration data of the module.

When the module OSP-B131 is configured within the OSP120, a manual operation of
the module can be performed via the OSP Panel. See
chapter 3.3
For remote control operation refer to the operating manual.
