The purpose of a satellite system is operating switch modules that are located far away
from the switch unit, for example inside an anechoic chamber. In this scenario, the
non-conductive fiber-optic link, which can be easily fed through the shielding, avoids
electromagnetic interference.
When avoiding interference and long-distance remote operation are not required, you
can use a wired link instead of the fiber-optic link. The wired link also supplies power
from the R&S
OSP base unit to the satellite unit.
The satellite unit has the same link connectors as the remote control module, plus a
DC power supply connector and several status LEDs:
Figure 3-139: Connecters and LEDs on the rear panel of the R&S OSP-B200S2
[DC In]
= 4-pin, 28 VDC power supply connector (not required with [Wired Link])
[Power]
= Status LED indicating power supply
[Overheat]
= Status LED indicating excess temperature
[FOL]
= Fiber-optic link for remote communication with R&S
OSP-B200R
[Link / Busy] = Status LED indicating communication on the FOL or wired link
[Wired Link] = 9-wire copper link for power supply and remote communication with R&S
OSP-B200R
The module's on-board memory stores its configuration data.
The switch unit provides power supply and control via
two
module bus cables to two
module bus connectors on the module's printed board. The available module bus con-
nectors ("Mxx") are shown in
The R&S
in a standard switch unit, not in a satellite unit

OSP-B200S2.
The module is not represented in the software's user interface, and you cannot query
its presence by SCPI commands like

For the satellite system's description and operating instructions, refer to its user man-
