10.3.3 CPRI - Option R&S EXBOX-B85
The CPRI breakout board performs tests directly at the CPRI interface between the REC
(base station radio equipment control) and the RE (base station radio equipment).
The board contains the user interface to the R&S
EX-IQ-BOX, two different interfaces for
data exchange with the DUT, two interfaces for additional control & management infor-
mation exchange, and three general purpose interfaces.
On the front panel, two SFP cages support the optical link. The breakout board addition-
ally contains a differential electrical interface, realized by four SMA connectors.
The front panel also provides the connectors for C&M data exchange. For fast C&M, use
the Ethernet interface, and for slow C&M, the RS-232-C interface.
Three BNC connectors for general purposes, input or output, enable controlling the DUT,
or reading the signals from the DUT, such as for user-specific purposes. These connec-
tors are located on top of the breakout board.
Connect the breakout board directly at the user interface with the R&S
EX-IQ-BOX, i.e.
without using a cable. Use in all other interfaces the suitable cables and modules to make
sure that data transmission works properly.
