EX-IQ-
BOX is sending the signal to the DUT on this transmission line.
Remote command:
7.2.7.7
Input/Output
In this section, you can select the physical I/O interface.
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.
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.

"Loopback internal"
Assigns the internal loopback.
"None (1409.7208.02)"
Deactivates the input, if no connection is established.
Remote command:
7.2.7.8
General Purpose Input Output
Section "General Purpose Input Output" contains settings for control signals to or from
external devices. Use this feature to trigger external devices or to monitor several internal
clocks, as for example the Node B frame tick, or to use external signals to trigger the I/
Q recorder.
