Note that CPRI recommends to use optical transceivers that follow the High Speed Serial
Link standards. CPRI mainly transfers the signal via the optical connection.
Use the electrical connection at the SMA connectors for debugging routines.
Basically the R&S EX-IQ-BOX receives a CPRI signal via one of the optical interfaces
SFP1, or SFP2. SMA is used, primarily, to the diagnosis.
For test purposes, the signal can be looped back internally. Then all the signal processing,
as well as the CPRI transmitter and receivers operate normally without having an external
device to be connected.
Difference between the R&S EXBOX-B85 breakout board versions
●
1409.7208.02 supports multiple outputs.
●
1409.7208.04 is limited to a corresponding I/O interface.
Input (1409.7208.02) ; Input/Output (1409.7208.04)
Determines the interface for signal input, and for EXBOX-B85 version 1409.7208.04, also
for the signal output.
Note that only one interface can be active at the same time.
If you are working with a CPRI breakout board 1409.7208.02, the R&S EX-IQ-BOX can
receive a signal via one of the optical interfaces SFP1 or SFP2. The EXBOX-B85 break-
out board 1409.7208.04, however, has only one interface.
"SFP1/2 (1409.7208.02)"; "SFP (1409.7208.04)"
Selects the SFP ( S mall F orm-factor P luggable) interface for connection
with the DUT.
"SMA" Selects the SMA ( S ub M iniatur version A ) interface.
"Loopback internal"
Assigns the internal loopback.
"None (1409.7208.02)"
Deactivates the input, if no connection is established.

Outputs
Determine the interface for signal output, that means align the transmitter type of the
DUT.
For the signal output, more than one interface can be activated simultaneously, for exam-
ple SFP1 for signal transmission to the DUT, and SMA for the signal monitoring.
"SFP1 / 2" Select the respective SFP ( S mall F orm-factor P luggable) interface, at
which the R&S EX-IQ-BOX is connected to the DUT for sending the
signal.
