Figure 5-49: Module R&S OSP-B142 (variant .03 with 3 DP3T switches)
The relays are mounted directly in the module front panel. All the RF connectors are
SMA female types. All relays are plugged into a kind of backplane; this way the module
is of compact size and no cabling to the relays is required.
The R&S OSP-B142 module is supplied with power and controlled from the R&S OSP
base unit via a single interface connector on the module’s printed circuit board; the
connection is done via a single connection cable.
The R&S OSP-B142 module is equipped with on-board memory to store the
configuration data of the module.
The R&S OSP-B142 exists in four different variants:
Variant
